Add part number 750-424 to your Quote. 750-424 CE cULus,
The digital input module receives control signals from digital field devices (sensors, etc.). This input module incorporates a current loop which makes it possible to monitor alarm contacts with a fixed resistance ratio (R1, R2), for intruder detection. The module indicates the current status of the contact via LEDs and via status bits in the process image.
