DOBOT Modbus IO Module M420T

DOBOT Modbus I/O Module M420T is an advanced, industrial digital output expansion module designed for expanding automation systems and integrating with robotic arms (e.g., DOBOT CR and CRA series). The device offers 16 isolated sink-type digital outputs (DOs) that can be used as standard control outputs (e.g., for relays, valves) or fast pulse generators (from 10 Hz to 300 kHz). Supporting Modbus TCP, Modbus RTU, and MQTT protocols via Ethernet and RS485 ports, the module guarantees reliable, stable communication in demanding industrial environments.
