Industrial Modbus RS485 RTU 8 Channel Relay Module

This 8-channel RS485 Bus Industrial Modbus Replay Module uses RTU protocol and it comes with multiple embedded protection circuits. These protection circuits include ADI magnetic isolation, TVS diode, power isolation, and reverse-proofing, etc. The Industrial Modbus RTU 8-ch Relay Expansion has a safe and durable enclosure that is made of ABS plastic. Using the Industrial Modbus 8-channel Relay Module is easy. Its communication speed is faster, it is more reliable, safer, and stable because it has been exclusively designed to suit industrial control applications and equipment.

Features of RS485 Bus Industrial Modbus RTU 8-ch Relay Module

• RS485 Bus facilitates cascading of multiple devices
• Configurable device address – 1~255
• Supports Argument to Command for Flash-On and Flash-Off functions (it enables the relay to automatically close after remaining ON for some time)
• Stable Voltage Isolation: On-board Unibody Power Supply Isolation | No need for additional power supply for the isolated terminal
• Signal Isolation: On-board Unibody ADI Magnetic Isolation | Low power consumption | Strong and reliable anti-interference
• Lightning-proof and Anti-electrostatic: on-board Transient Voltage Suppressor (TVS) | Efficient suppression of the surge voltage and transient spike in the circuit
• Voltage and interference protection: On-board Optocoupler Isolation to protect the relay from circuit interference and high voltage
• Reverse Protection | Reverse-Proof Circuit to ensure protection against accidental damage due to reverse connection or incorrect connection
• Relay Contact Rating: ≤10A 250VAC/30VDC
• 3x LED indicators for MCU and Signal Transceiving
• Reliable enclosure made of ABS plastic | Rail-Mounted
