Industrial Modbus RS485 RTU 8-ch Magnetic Latching Relay Module (C) With Digital Input
$36.9
Adopting magnetic latching relay, the relay status will remain unchanged after power failure
Supports setting device address (1~255) so that multiple devices can be cascaded through RS485 bus
With flash-on and flash-off functions, the relay can be controlled to automatically close after opening for a period of time through instructions
Onboard integrated power isolation can provide stable isolation voltage, and no additional power supply is required for the isolation end
Product Features
This product is an industrial-grade RS485 interface controlled 8-way magnetic latching relay module. The state of the relay will remain unchanged after power failure. It adopts Modbus RTU protocol, built-in power isolation, magnetic coupling isolation and TVS protection circuits, and adopts ABS shell design. This product is easy to operate and has the characteristics of fast, stable, reliable and safe communication. It can be applied to various industrial control equipment or applications with high communication requirements.
- With magnetic latching relay, the relay status will remain unchanged after power failure
- Supports setting device address (1~255) to cascade multiple devices via RS485 bus
- With flash-on and flash-off functions, the relay can be controlled by command to automatically close after being opened for a period of time
- Onboard integrated power isolation can provide stable isolation voltage, and no additional power supply is required at the isolation end
- Onboard integrated magnetic coupling isolation for signal isolation, high reliability, strong anti-interference and low power consumption
- Onboard resettable fuse and TVS (transient voltage suppressor) can effectively suppress surge voltage and transient spike voltage in the circuit, prevent overcurrent and overvoltage, lightning protection and anti-static
- Adopting special magnetic latching relay driver chip, the driving ability is stronger and more stable
- Onboard anti-reverse connection circuit to prevent the positive and negative poles from being reversed and burning the circuit
- Use high-quality relays to allow access to loads: ≤10A 250V AC or ≤10A 30V DC
- Rail-type ABS protective housing, easy to install and use, safer with housing
- Three external LED indicators are provided to facilitate viewing of the MCU status and signal receiving and sending status
Product Parameters

TXD: Send indicator light, the light is on when sending data
RXD: receiving indicator light, the light is on when receiving dataBasic Functions
Supports sending Modbus RTU commands to control relays via RS485, thus controlling various devices
Onboard multiple isolation protection circuits
Multiple protections, safer and more reliable to use
Guide rail housing design
Rail-type ABS protective housing, easy to install and use, safer with housing
RS485 communication
Supports setting device address (1~255), and multiple devices can be cascaded through RS485 bus.
When there are many cascaded devices and the communication distance is far, it is necessary to add RS485 repeater according to the actual application environment
The picture is for display only, this product does not include USB to RS485
Relay Wiring
The device has a relay with a contact rating of 10A 250V AC or 10A 30V DC
