This data brief details the features of the PCLT-2A sensor input termination. The PCLT-2A is a dual termination device for the front-end of a 24 V DC digital input module. Composed of an input-voltage protection, a serial current-limiter circuit and an output driver, each channel circuit terminates the connection between a high-side proximity sensor and the I/O module. Because of its IEC type programmability and the isolated/non-isolated output options, the PCLT offers a flexible and easy-to-design solution for highly integrated I/O modules.
