16 Channel Relay Module DC 12V MODBUS RTU RS485 Relay Module Board PLC Controller Serial Port Switch Standby Current 11MA

Product Information

Modbus relay module can via RS485/TTL UART interface received from host computer /MCU’s Modbus RTU command to perform related operations. It features embedded protection circuits such as power isolation, ADI magnetic isolation, and TVS diodes. To make your hunt for modbus relay easier, utilize the multiple filters to narrow down your selection.

Due to its fast communication, stability, reliability, and safety, it is an ideal choice for industrial control equipment and/or applications with high communication requirement.The power supply of this product is not included, it is recommended to purchase 12V power supply if you need it.

If you need to solder anything to your product or make any other modifications please make sure that you test the product is working first. LC 2-way Modbus relay module equipped with mature and stable 8-bit MCU and RS485 level communication chip,adopt standard MODBUS RTU format RS485 communication protocol. Built-in single ADI magnetic isolation provides signal isolation, ensuring high reliability, strong anti-interference, and low power consumption. Model: R4S8CRMBSpecifications:Relays have Normally Open (NO) and Normally Closed (NC) Contacts each capable of switching max: .This product is an industrial 32-ch relay module controlled via RS485 bus, adopts Modbus RTU protocol, built-in protection circuits such as power supply isolation, magnetical isolation, resettable fuse, and TVS diode, etc.

Specifications: Relays have Normally Open (NO) and Normally Closed (NC) Contacts each capable of switching max. This is USB Relay Module with ModBus RTU protocol support and 16 relays (the type is selectable during purchase). Just connect the power and RS485 to the first module and ribbon cable connect the remaining modules to form a compact IO station without the wiring costs. It features embedded protection circuits such as power isolation, ADI magnetical isolation, and TVS diode, etc.I already started constructing the node-red flow i can compare the wattage passing thru SDM 630 on each phase and then make something. Built-in single power supply isolation provides stable isolated voltage without the need for an additional power supply for isolated terminals.
