Modbus RTU 16-Ch Relay Module, RS485 Interface, with Multiple Isolation Protection Circuits, Industrial-Grade, Rail-Mount Case (Modbus RTU Relay 16CH)
Onboard unibody power supply isolation, provides stable isolated voltage, needs no extra power supply for the isolated terminal. Onboard unibody ADI magnetical isolation, allows signal isolation, high reliability, strong anti-interference, low power consumption. Onboard resettable fuse and TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, provides over-current/over-voltage proof, lightningproof & anti-electrostatic
Onboard Optocoupler isolation, prevent the relay from being interfered by high-voltage circuit. Onboard dedicated relay driver chip, with built-in freewheeling diode protection, the driving ability is stronger and more stable. Reverse-proof circuit, prevent the circuit from being damaged accidentally by incorrect connection. High quality relay, contact rating: ≤10A 250VAC/30VDC
[RS485 Communication] Configurable Device Address (1~255), Multi Devices Can Be Cascaded On RS485 Bus. In Case Of Many Devices Are Cascaded, Or The Communication Distance Is Quite Long, It Is Necessary To Use RS485 Repeaters
[Relay Connection] Contact Rating Of The Onboard Relay Up To 10A 250VAC/30VDC. Directly Controlling 220VAC Home Appliances, Or Devices Below 30VDC
