Key features

Specialized remote I/O for AC31 system, reducing local CPU load and enabling distributed control

Can be expanded with 6 modules, flexibly expanding on/off quantities / analog quantities, suitable for medium and large-scale systems

AC230V direct power supply + relay output, eliminating on-site DC power supply, directly driving AC contactors, valves

Remote connection via bus, saving wiring costs and enhancing system stability Application scope

Remote I/O expansion for AC31 50 series PLC (such as 07KR51 master station)

Distributed automation systems (workshop equipment, assembly lines, HVAC, water treatment)

Scenarios where only AC220V power supply is available on-site and remote control of AC loads is required
