Dual Ethernet Ports

The dual ports allow for easy daisy-chaining of units.


Flush mounted or fitted to a a standard DIN rail, multiple units can be stacked on on top of each other to provide a compact installation.


A watchdog timer can force outputs to preset states on LAN fail (can be disabled)


Industrial grade isolation between the Power supply, IO and Ethernet port


The unit is configured using the free WTDUtility Software. This can be used to set the units' IP address, to set the watchdog alert relay output states and to test the relays.
