System compatibility

AS-H810-1208 belongs to MODICON 984 series mixed digital I/O module. Compatible with MODICON 984 CPU and 984 rack backplane. It collects field digital switch signals and outputs switching control signals to actuators. Suitable for chemical plant,water treatment,packaging machinery,conveyor line legacy Modicon PLC system renovation and replacement as industrial spare part.

Function

AS-H810-1208 combined digital I/O module. It receives digital signals from field limit switches,proximity switches and push buttons,transmits input status to MODICON 984 PLC CPU. 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 acquisition and control in legacy Modicon 984 automation system, serving as reliable discrete I/O spare part.

Installation

Cut off rack power before installation. Insert AS-H810-1208 module into MODICON 984 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.

Interface
