16 Point Control Interface Module IC693MDL645 24 Volt DC Positive / Negative Logic Input

 

 

 

The 24 volt DC Positive/Negative Logic Input module for the Series 90-30 Programmable Logic Controller provides 16 input points in one group with a common power input terminal. This input module is designed to have either positive logic or negative logic characteristics. Input characteristics are compatible with a wide range of user-supplied input devices, such as pushbuttons, limit switches, and electronic proximity switches. Current into an input point results in a logic 1 in the input status table (%I). Power to operate the field devices can be supplied by the user, or an Isolated +24 VDC supply on the power supply (+24V OUT and 0VOUT terminals) can power a limited number of inputs.

 

 

 

LED indicators which provide the ON/OFF status of each point are located at the top of themodule. This LED block has two horizontal rows with eight green LEDs in each row; the top row labeled A1 through 8 (points 1 through 8) and the bottom row labeled B1 through 8 (points 9 through 16). An insert goes between the inside and outside surface of the hinged door. The surface towards the inside of the module (when the hinged door is closed) has circuit wiring information, and circuit identification information can be recorded on the outside surface. The outside left edge of the insert is color-coded blue to indicate a low-voltage module. This module can be installed in any I/O slot of a 5 or 10-slot baseplate in a Series 90-30 PLC system
