The MODBUS RTU Relay Output Module, Model TDO340, is a reliable 4-channel SPST device with independent contacts. It fully supports the MODBUS RTU protocol, allowing the relay status to be configured both at startup and in the event of communication loss, ensuring continued system protection. The module is equipped with a watchdog function that detects communication errors and takes action to maintain security. In addition, the TDO340 uses non-volatile memory to retain and restore relay states after power interruptions. The unit can be used as a relay output extension for MODBUS RTU master units.
