This digital input module receives control signals from field devices (e.g., sensors). Each input module has a noise-rejection filter. Field and system levels are electrically isolated.

 Number of digital inputs : 4

Total number of channels (module) : 4 

 Signal type : Digital 

 Signal type (voltage) : 24 VDC 

 Sensor connection : 2 x (2-wire, 3-wire). A suitable field side connection module (e.g., 750-614) must also be used to connect other sensors.   Input characteristic : low-side switching 

 Input filter : 3 ms 

 Input current per channel for signal (0) typ. : 7 mA 

 Voltage range for signal (0) : (UV - 5 V) … UV DC 

 Voltage range for signal (1) : −3 VDC … (UV - 15 V) 

 Sensor supply 24 VDC Input data width (internal) max. : 4 bits 

 Supply voltage (system) : 5 VDC via data contacts 

 Current consumption (5 V system supply) 5 mA 

 Supply voltage (field) 24 VDC (-15 … +20 %); via power jumper contacts (power supply via blade contact; transmission (field side supply   voltage only) via spring contact)

 Isolation : 500 V system/field Indicators LED (A-D) green: Status DI 1 … DI 4 

 Number of incoming power jumper contacts : 2
