This module must be used in a series B or later 1771 I/O chassis. The
1771-ID16 is not compatible with the 1771-AL local I/O adapter.
This module contains customer-selectable input filtering to limit the
effects of voltage transients caused by contact bounce and/or radiated
electrical noise. The delay due to filtering is 9.0 or 18.0ms for
turning ac inputs on to off, and 0.57ms for turning ac inputs off to
on: 9.0ms for turning dc inputs on to off, and 0.57ms for turning dc
inputs off to on. The filter time is factory set to 9.0ms.
The module is designed to operate with limit switches, float
switches, selector switches, and pushbutton switches.
