Allen Bradley TTL Input Module, CAT # - 1771-IG
Allen Bradley TTL Input Module, CAT # - 1771-IG. This module contains input filtering to limit the effects of voltage transients caused by contact bounce and/or radiated electrical noise. The delay due to filtering is less than 1 ms. The TTL module requires power from two sources: the I/O chassis backplane, and a +5V DC power supply that you provide for transmission of TTL signals.
