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