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 It is also compatible with the now superseded ‘ZEN-16’ product.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.
