Introduction
2-channel digital input terminal thermistor
The digital EL1382 input terminal analyses the input signal of thermistor sensors with the aid of a current loop and a voltage < 5 V. The EL1382 is a monitoring device for the thermal machine protection of PTC sensors and id suitable for the direct monitoring of motors, bearings and plants. In the process image, the state of the sensor is indicated by one bit each. A further bit reports short circuits or line interruptions. The LEDs indicate the state of both input bits in red or green.
