32-Channel Relay RS485 Modbus RTU Relay 32CH
The RS485 32-CH Relay Module is an industrially deployable 32-channel relay that is controlled via the RS485 bus and uses the Modbus RTU protocol. It provides numerous protection circuits, easy handling, and reliable performance for industrial control applications. With a contact rating of ≤10A 250VAC/30VDC, it is ideal for controlling household appliances and devices under 30VDC. The rail-mounted ABS housing allows easy and safe installation.
Recommended Accessories:
- Industrial USB to RS485 Converter
- Industrial USB to RS485/422 Converter FT232RL
- 5V DC 2000mA Wall Adapter AC/DC Adapter 5.5mm/2.1mm Plug
Features:
- The relay has configurable device addresses between 1 and 255.
- The Flash-ON, Flash-OFF function allows the relay to automatically turn off after a period.
- The relay has resettable TVS fuses to suppress overvoltages and voltage spikes.
- The built-in relay driver chip with built-in freewheel diode protection, provides stronger and more stable control capability.
- The ADI insulation allows signal isolation, high reliability, strong anti-interference, and low power consumption.
- The optocoupler isolation prevents the relay from being disturbed by high voltage circuits.
- The circuit is reversal polarity protected and protects against accidental wrong connections.
- The relay has a rail-mountable ABS housing which is easy to install and safe in use.
- The relay has 3LEDs as status indicators.
