Digital input modules, electrically isolated
5.3.1 PCD2.E500, 6 digital inputs for 115 - 230 VAC
Application
Module with 6 electrically isolated inputs for alternating current. The inputs are set up
for source operation and have one common “COM” terminal. Only the positive half-
wave of the alternating current is used.
Technical data
