  • ZEN-RIO Relay I/O Expansion for the Zen Datalogger

    Adds 16 Relay Outputs & 16 Digital Control Inputs


    What it does:
    The Rio expands the Zen Datalogger capabilites - adding 16 more relays and digital I/O.

    The ZEN-RIO is a relay output and digital input expansion which is designed for seamless integration with the Zen Datalogger control and monitoring station. It is also compatible with the now superseded 'ZEN-16' product.

    At a glance:

    • The perfect add-on to extend your Zen Datalogger: Effortlessly adds 16 relay outputs and 16 digital control inputs
    • Ideal for on/off control and alarm or status control

    The ZEN-RIO’s relays are controlled directly by the Zen Datalogger’s setpoints, which are in turn easily configured using our user-friendly and flexible WorkBench software. The digital control inputs are designed for SCADA applications and can be read directly from the Zen Datalogger’s com ports.
