Description

The CLT3-4 is a quadruple input digital

termination device designed for 24 V dc

automation applications. It provides the front-end

circuitry of a digital input module (I/O) in industrial

automation, and drives an isolating opto-coupler.

Figure 1.

The pins ESD, COM

13, 15, 16, 18, 20) must be connected together

externally. This common pad COM is enlarged to

reduce the thermal resistance and improve the device

cooling. The COM and IN pins are designed to

minimize the EMI effects on the circuit.
