Discrete Input Expansion Module 8SK485 for Controller Functionality Enhancement

It is an external module for extending the functionality of compatible controllers. The product operates from a constant voltage source of 12 V. The product is equipped with discrete inputs, which can be used both to monitor sensors with dry contact output, and to monitor the integrity of the cable through a dedicated pair in it for 3 states: normal, open and short circuit. The product transmits the state of discrete inputs via the physical interface RS-485.
