    ZEN-16 has been retired

    Clarity for consulting-specifying engineers and you

    The ZEN-16 was an incredibly powerful and flexible piece of hardware suitable for hundreds of different applications. But despite this, customers were often confused about whether it was right for their specific application. We have responded to this by creating 2 new Zen products and narrowing the scope of each of them.

    Introducing the Zen RTU and the Zen Datalogger

    The Zen RTU is ideal for applications which require collation of multiple signals routed directly to a master console such as a SCADA system or PLCs. Available in RTU/U (isolated universal input) and RTU/R (non-isolated RTD input) models.

    It has four digital inputs and a RS485 Modbus/RTU port.


    The Zen Datalogger most closely resembles its predecessor, the ZEN-16, and much of its capabilities are the same. It is suitable for applications which require collection and visualisation of data from multiple sources.

    It has 2 analog outputs and 2 relay contact outputs for control and alarm applications.
