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

Included Software

The unit is configured using the free WTDUtility Software. This can be used to set the units' IP address and to set the input ranges.


Optional Software


RealView is a Windows data logging and chart recorder application, which records and plots measured values from analogue hardware devices in real-time. Several curves can be plotted into a single chart. Several charts can be arranged on one or more pages if necessary. Plot options like pen width or pen colour can be altered to suit. Chart screen shots can be captured, charts printed with annotations and raw data can be exported to Excel.
