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.
