KL1382 | 2-channel digital input terminal thermistor

The digital KL1382 input terminal analyses the input signal of thermistor sensors with the aid of a current loop and a voltage 5 V. The KL1382 is a monitoring device for the thermal machine protection of PTC sensors, suitable for the direct monitoring of otors, bearings and equipment. In the process image, the state of the sensor is indicated by one bit each. A further bit reports short-circuits or line interruptions. Red or green LEDs indicate the state of the two input bits.
