Modbus RTU 16-Ch Relay Module, RS485 Interface, with Multiple Isolation Protection Circuits, Industrial-Grade, Rail-Mount Case (Modbus RTU Relay 16CH)

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
• [Applications] Industrial Control, Smart Home, Smart Agriculture, Breeding & Farming
