The WTD678C is a Ethernet Modbus TCP unit with 8 opto-isolated digital inputs with pulse counting and 8 opto-isolated transistor outputs with PWM support. Part of a no-frills industrial range featuring 3-way isolation, dual LAN ports for easy daisy chaining, DIN rail mount with the ability to stack modules one on top of another, watchdog with settable output state condition on comms fail. Compatible with all SCADA software talking Modbus/TCP.
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.
