Installation Instructions
Cat. No. 1771-ID16 Series B
Use this document as a guide when installing the ac Isolated Input
module.
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.

- Page 7 ac/dc (120V) Isolated Input Module The 1771–ID16/B module is a modular component of the 1771 I/O system requiring a properly installed system chassis. Refer to publication 1771–IN075 for detailed information on acceptable chassis, proper installation and grounding requirements. Limit the maximum adjacent slot power dissipation to 10W maximum.
- Page 8 ac/dc (120V) Isolated Input Module Connections to the input module are made to the 40 terminal field wiring arm (cat. no. 1771-WN) shipped with the module. Attach the wiring arm to the pivot bar on the bottom of the I/O chassis. The wiring arm pivots upward and connects with the module so you can install or remove the module without disconnecting the wires.
