GE IC693MDL632 125 Volt DC Positive/Negative Logic Input, 8 Point
125 Volt DC Positive/Negative Logic Input, 8 PointIC693MDL632
This 125 volt DC Positive/Negative Logic Input module provides 8 input points in two isolated
groups with four points in each group. Each group has a separate common associated with it
(the two commons are not tied together inside the module). The input module is designed to
have either positive logic characteristics in that it sinks current from the input devices to the
user common or negative power bus, or negative logic characteristics in that it sources current
through the input devices to the user common or positive power bus. The input device is
connected between the power bus and the module input. Current into an input point results in a
logic 1 in the input status table (%I). Input characteristics are compatible with a wide range of
input devices, such as pushbuttons, limit switches, and electronic proximity switches. Power
to operate field devices must be supplied by the user.
LED indicators which 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. This
module uses the top row labeled A1 through 8 (points 1 through 8). 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 red to indicate a high-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
