Isolated Input module provides 16 isolated input points in one group with a common power input terminal. The ON and OFF response times for this module are 1 mSec maximum. This input module is designed to be used in either positive logic or negative logic applications. Input characteristics are compatible with a wide range of user-supplied input devices, such as pushbuttons, limit switches, and electronic proximity switches. Current flow into an input point results in a logic 1 in the Controller’s input status table (%I). An insert fits between the inside and outside surface of the module’s hinged cover. The back of the insert has circuit wiring information, and circuit identification information can be written on the front of the insert. The front left edge of the insert is color-coded blue to indicate a DC-type module.
