System compatibility

7428-042-248096 belongs to MODICON A series discrete I/O module. Compatible with MODICON A series CPU, backplane and rack power supply modules. It is used for field digital switching signal acquisition and control output. Suitable for chemical plant,water treatment,packaging machinery,conveyor line old AEG Modicon PLC system renovation and replacement as industrial spare part.

Function

7428-042-248096 discrete I/O module. It collects digital signals from field limit switches,proximity switches and push buttons,transmits signal status to MODICON PLC CPU. Meanwhile it receives control commands from CPU and outputs 24VDC switching signals to drive solenoid valves, relays and indicator lights. Built-in channel short-circuit protection and hardware self-diagnosis function. Each channel has LED status indicator. Widely used for digital on-off signal control in legacy AEG MODICON automation system, serving as reliable I/O spare part.

Installation

Cut off rack power before installation. Insert 7428-042-248096 module into MODICON A series backplane slot and lock the card. Check gold finger contact condition. Connect field sensor and actuator wiring to terminal block. Configure I/O address mapping,verify input reading and output action,complete function test before formal operation.
