FLEX 4xDI DC 24 V
The electronic module collects the binary control signals from the process level and
transmits them isolated to the central bus system. It has 4 channels and their status is
monitored via LEDs.
•
4 digital inputs, isolated to the backplane bus
•
Suited for switches and approximate switches
•
Status indication of the channels via LEDs also with de-activated electronic power
supply
