This 48 volt DC Positive/Negative Logic Input module for the IC693-Series Programmable Logic Controller provides 16 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 PLC input status table (%I). Power to operate input devices must come from an external power 48 VDC source supplied by the user. LED indicators that provide the ON/OFF status of each point are located at the top of the module. This LED block has two horizontal rows with eight green LEDs in each row; the top row is labeled A1 through 8 (points 1 through 8) and the bottom row is labeled B1 through 8 (points 9 through 16). 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. This module can be installed in any I/O slot of a 5 or 10-slot baseplate in an IC693-Series PLC system.
