The 24 volt DC Positive/Negative Logic Input module,

IC694MDL645, provides 16 input points in one group with a common

power input terminal. This input module can be wired for either

positive logic or negative logic. Input characteristics are compatible

with a wide range of 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). Field devices

can be powered from an external supply. Depending on their

requirements, some input devices can be powered from the module’s

+24V OUT and 0V OUT terminals.

Sixteen green LEDs indicate the ON/OFF status of points 1 through

16. The blue bands on the label show that MDL645 is a low-voltage

module.

This module can be installed in any I/O slot in an RX3i system.
