This module contains filtering to limit the effects of voltage transients caused by contact bounce and/or radiated electrical noise. The delay due to filtering is nominally 18ms (+10ms) for turning ac inputs on or off. This module is designed to operate with ac proximity switches and other input devices with an off-state leakage current less than 2.8mA peak.

The module receives its power through the 1771 I/O chassis backplane from the chassis power supply. The module requires 80mA from the output of this supply .Add this current to the requirements of all other modules in the I/O chassis to prevent overloading the chassis backplane and/or backplane power supply.

Make wiring connections to the module through the 10 terminal field wiring arm (cat. no. 1771-WA). The arm pivots on the I/O chassis to connect with terminals on the front of the module and acts as a terminal strip. The wiring arm allows the module to be removed from the chassis without disconnecting the wiring.
