The STEVAL-BFA001V1B is an industrial reference design kit designed for condition monitoring (CM) and predictive maintenance (PdM). The hardware development kit consists of an industrial sensor board (STEVAL-IDP005V1), an adapter for the ST-LINK/V2-1 programming and debugging tool (STEVAL-UKI001V1), a 0.050" 10-pin flat cable, a 4-pole cable mount connector plug with male contacts and an M12 female connector with a 2 m cable. The firmware package includes dedicated algorithms for advanced time and frequency domain signal processing and analysis of the 3D digital accelerometer with 3 kHz flat bandwidth. The package includes drivers for pressure, relative humidity and temperature sensor monitoring. Audio algorithms for acoustic emission (AE) are also part of the package. The firmware runs on the high performance STM32F469AI, ARM®Cortex®-M4, 32-bit microcontroller and the sensor data analysis results are sent via wired connectivity based on IO-Link device transceiver (IO-Link stack protocol not included). The STEVAL-BFA001V1B reference design is suitable for monitoring motors, pumps and fans, and can accelerate the development of predictive maintenance solutions. The package also allows connection with the STEVAL-IDP004V1 IO-Link master capable, multi-port evaluation board; a PC GUI included in the package displays the algorithms output and sensor data. The data can also be displayed on a PC using a common terminal emulator by simply connecting the STEVAL-IDP005V1 to a PC through the STEVAL-UKI001V1 adapter and ST-LINK/V2-1 included on any STM32 Nucleo-64 development board. The package includes an industrial M12 cable for power or connection with a master port. The connection is managed using a standard multipolar cable with one wire used for IO-Link data, one for the L+ line (positive supply voltage pole) and one for the L- line (negative supply voltage pole). The layout is designed to meet IEC61000-4-2/4 and EN60947 requirements for industrial applications. The STEVAL-IDP005V1 is specifically designed with dimensions (50mm x 9mm x 9mm) that reflect real industrial applications and needs. The firmware is freely available on STSW-BFA001V1.

The STEVAL-IFP001V1 demonstration board implements the functions of the VN808CM-E, an 8-channel high-side driver with CMOS compatible voltage levels in industrial applications, and is developed using VIPower M0-3 proprietary technology. The VN808CM-E completes the series of octal high-side drivers for the factory automation market. It is intended for driving any kind of load with one side connected to ground and can be driven by using a 3.3 V logic supply. Active current limitation, combined with thermal shutdown and automatic restart, protects the device against overload. The STEVAL-IFP001V1 is compliant with international electromagnetic compatibility (EMC) specifications as well as EMC immunity proof 4 kV level EFT (IEC 61000-4-4), and 2 kV voltage surge (IEC 61000-4-5), and has been tested at different typical ambient temperatures. It is suitable for use in programmable logic controllers to produce the related digital outputs according to IEC standards. The STEVAL-IFP001V1 is also based on the SM15T33A, a unidirectional Transil™ diode.

The purpose of this design is to demonstrate the features of the VN751PT high-side driver. The application offers robustness and complies with EMC industrial standards. It implements short-circuit/overload protection and thermal management as well, achieving best in class MTBF values. The reference design is suitable for use in programmable logic controllers (PLCs) as well as to drive generic loads which require up to 2.5 A of nominal current (the typical current limitation is 4.5 - 5 A). Thanks to the very low RDSon (only 60 mO Typ. @ 25 °C) the device allows very low power consumption during the operation and for this reason it represent an ideal solution for IP65 / IP67 requirements. The device is compliant with IEC 61131-2 (programmable controllers international standard).

The STEVAL-IFP016V2 IO-Link communication master transceiver demonstration board is based on the L6360, monolithic IO-Link master port. A modular and customizable application that interfaces externally with the microcontroller. The purpose of the board is to demonstrate the capability of the L6360 monolithic IO-Link master, as communication transceiver for multiple I/Os. The board uses input signal from the microcontroller and outputs the 24 V required for industrial applications. The board demonstrates that the L6360 is both IO-Link master port mode and standard IO mode compliant. The interface is compatible with the STEVAL-PCC009V2 and STEVAL-PCC009V1 EMC-immune application against ESD, burst, surge, RF noise, etc., according to IEC61000-4-2, IEC61000-4-4, IEC61000-4-5, and IEC61000-4-6 standards. A large GND area on the printed circuit board has been designed in order to minimize noise and ensure good thermal performance. The small size of the L6360 package with a reduced pin number, along with the small size of the application area, allow the user to work in applications where space constraint is critical. The L6360 is a monolithic IO-Link master port, compliant with PHY2 (3 wires) supporting COM1 (4.8 kbaud), COM2 (38.4 kbaud) and COM3 (230.4 kbaud) modes. The output stage (high-side, low-side or push-pull) as well as the cutoff current, cutoff current delay time, and restart delay, are programmable by I2C protocol. The cutoff current and cutoff current delay time, combined with the thermal shutdown and automatic restart, protect the device against overload and short-circuit. The output stages are able to drive resistive, inductive and capacitive loads. Fast demagnetization is able to dissipate the energy stored in the inductive loads.

The VNI414K (for loads up to 0.6 A) and VNI4140K-32 (for loads up to 1.0 A) are monolithic 4-channel drivers featuring very low RDS(on) and per-channel diagnostic. The ICs, realized in STMicroelectronics™ VIPower™ technology, are intended to drive any kind of load with one side connected to ground. Active channel current limitation combined with thermal shutdown, independent for each channel, and automatic restart, protect the device against overload. A channel in an overload condition overheats and turns OFF and back ON automatically in order to maintain its junction temperature between TTSD and TR. If this condition makes case temperature reach TCSD, the overloaded channel is turned OFF and restarts only when case temperature has decreased down to TCR. In case of more than one channel in overload, restart of the overloaded channels is not simultaneous, in order to avoid high peak current from the supply. Non-overloaded (non-overheated) channels continue operating normally. The four open drain STATUSX output pins indicate per-channel overtemperature conditions.

The STEVAL-IFP022V1 demonstration board is based on VNI8200XP high-side driver. It was developed as an instrument to test device functionality in terms of power management and digital interface. As required by industrial standards, the board’s isolated interface between the IPS and host controller were implemented using high-speed opto-couplers for IPS driving, and low-speed opto-couplers to receive device status information. The connection is achieved through a 30-pin connector. To provide a user-friendly way to test VNI8200XP device functionality, a GUI interface was developed. To use the GUI it is necessary to connect the STEVAL-IFP022V1 demonstration board to a PC by using a communication board (part number STEVAL-PCC009V2). Thermal performance is improved thanks to a four-layer structure which makes it possible to design a copper area distributed in all the layers for more effective heat dissipation. The STEVAL-IFP022V1 demonstration board meets EFT standard requirements IEC 61000-4-2, IEC 61000-4-4, IEC 61000-4-5.

The STEVAL-IFP048V1 is an industrial digital output expansion board based on ISO808A-1 and compatible with STM32 Nucleo. It provides a powerful and flexible environment for the evaluation of the driving and diagnostic capabilities of the ISO808A-1 octal high-side smart power solid state relay, with embedded galvanic isolation and 20MHz SPI control interface, in a digital output module connected to 1.0 A industrial loads. The STEVAL-IFP048V1 directly interfaces with the microcontroller on the STM32 Nucleo driven by GPIO pins and Arduino® R3 connectors, ensuring connectivity with either a NUCLEO-F401RE or a NUCLEO-G431RB development board. The galvanic isolation between the microcontroller and the process stage is guaranteed by the ISO808A-1. It is also possible to evaluate a 16 channel output system enabling the daisy chaining feature on two STEVAL-IFP048V1 stacked expansion boards.
