Description
The Allen-Bradley 1771-IV PLC-5 Digital DC Driver Logic Input Module is compatible with the following 2 and 3-wire devices:
- DC proximity switches
- Photoelectric sensors
- Pushbuttons
- Limit switches
- Float switches
- Selector switches
When using a 3-wire input device, the input device must be capable of sinking an on-state minimum current of 8mA @ 12VDC up to 24mA @ 24VDC. The off-state leakage current of the 3-wire device should not exceed 1mA.
The module contains input filtering to limit the effect of voltage transients caused by contact bounce and/or radiated electrical noise. The delay due to input filtering is nominally 15+/- 7ms for turning inputs on, and 15+/-7ms for turning inputs off.
