4-CHANNEL DIGITAL INPUT MOUDLE DC 24 V POSITIVE SWITCHING CARRIER RAIL DIN 35 CAGE CLAMP CONNECTION
The digital input modules receive control signals from digital field devices (sensors, etc.). Each input module has a noise-rejection filter. This filter is available with different time constants. An optocoupler is used for electrical isolation between the bus and the field side.
