2-CHANNEL DIGITAL INPUT MODULE AC 230 V CARRIER RAIL DIN 35 CAGE CLAMP CONNECTION 2- TO 4-CONDUCTOR-CONNECTION
The digital input module receives control signals from digital field devices (sensors, etc.). The module is a 2-channel, 4-conductor device and sensors with a ground (earth) wire may be directly connected to the module. An optocoupler is used for electrical isolation between the bus and the field side. Attention: An additional supply module must be added for operation with AC 230 V!
