Product Description:
The 240 volt AC Isolated Input module for the Series 90-30 Programmable Logic Controller
provides 8 isolated input points, each with a common power input terminal. The input circuits are
reactive (resistor/capacitor) inputs. 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 user-supplied input
devices, such as pushbuttons, limit switches, and electronic proximity switches. Power to operate
the field devices must be supplied by the user. This module requires an AC power source, it
cannot be used with a DC power source.
LED indicators which provide the ON/OFF status of each point are located at the top of the
module. This LED block has a horizontal row with eight green LEDs 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.
