Teracom TDO340 Modbus RTU Relay Module
MODBUS RTU relay output module, TDO340, is a reliable 4-channel SPST device with independent contacts.
It supports the MODBUS RTU protocol and allows you to set relay safety statuses at startup and during communication loss, ensuring your system remains secure.
The module includes a watchdog function that monitors communication failures and responds quickly to maintain safety. The TDO340 uses nonvolatile memory to remember relay states and restore them after power cycling.
It serves as an ideal relay output extension for MODBUS RTU master devices, with an RS-485 interface supporting up to 63 nodes.
Additional features include an LED indicator for communication status and a wide supply voltage range starting from 5VDC. The module also offers reinforced isolation for relay contacts, adding an extra layer of safety to your system.
A built-in 120-ohm termination resistor and easy DIN rail mounting make installation straightforward. Firmware updates can be done via the interface, simplifying maintenance.
