The Modbus RD-8 digital output module has 8 transistor outputs.
The outputs can take two states: ground potential or power input potential. The maximum load of a single output is 2A. The device is controlled by the Modbus RTU protocol over the RS-485 bus. The free application allows you to control up to 4 modules.
