This digital input module receives control signals from field devices (e.g., sensors).
The module is a 4-wire device allowing direct connection of sensors with functional ground contact.
Each input module has a 3.0 ms noise-rejection filter.
Field and system levels are electrically isolated.
When using the functional ground CAGE CLAMP® connection, the field power must be reapplied after every seven digital input modules (750-407/040-000)!
The device is ideal for operation in extreme environments thanks to:
- An extended temperature range
- Greater immunity to impulse voltages and electromagnetic interference
- Higher vibration and shock resistance
