Enables sophisticated monitoring and control of up to 16 input signals from a variety of sources

Get 16 signals into your PLC or SCADA system

If you need to collate multiple signal input types and route them to your PLC or SCADA system, choose the Zen RTU. This exceptionally flexible and powerful monitoring and control station is the last word in RTU technology.

Enjoy the flexibility of universal inputs

If you need to collate multiple signal input types and route them to your PLC or SCADA system, choose the Zen RTU. This exceptionally flexible and powerful monitoring and control station is the last word in RTU technology.

Cleans up noise

Each of the Zen RTU channels is isolated so there’s zero cross-talk.

Set up in just minutes

No calibration and simple software set up with WorkBench.
