The OptoMOS® line of solid state relays uses discrete semiconductor components and the patented OptoMOS® architecture to deliver fast, reliable, bounce-free switching in a compact design. From small single-pole, 4-pin relays to multi-pole and multi-function devices, OptoMOS® products are an ideal solid state replacement for larger reed and electromechanical relays. Compared to these old electromagnetic technologies, our OptoMOS® relays offer significantly lower drive current, small package size, no susceptibility to magnetic interaction, and solid state reliability. All of these are key requirements for the design of today's complex, low-power, multi-channel products. The small 4-pin SOP relays combine our state-of-the-art double-molded, vertical-construction packaging with high performance to give you a reliable product with up to 20% savings in board space compared to other 4-pin SOP products. The dual-pole OptoMOS® relays combine two independent relays into a single 8-pin package, paving the way for designers to condense more functionality into a single component.

PC-100-LLC-CZ is a liquid level control relay with an input voltage ac of 95–120 and an adjustable probe sensitivity from 4.7–100 kΩ.

PC-100-LLC-GM is a liquid level control relay with an input voltage ac of 95–120 and an adjustable probe sensitivity from 4.7–100 kΩ.

PC-102CICI-DL is a dual seal-leak detector that uses inputs to sense seal failures and energize the output relay. Input logic (direct or inverted) is DIP-switch selectable. See datasheet for detailed technical characteristics.

PC-102CICI-LT is a seal-leak and over-temperature detector that uses one input to sense seal failures and the temperature input to detect motor overheating. This unit is configurable to suit various probes. Seal input logic (direct or inverted) and over-temperature trip reset (automatic or manual) is DIP-switch selectable. See datasheet for detailed technical characteristics.
