ZEN-RIO

Relay I/O Expansion Unit

› The perfect companion for the

ZEN-16 Control Station

› Adds 16 relay outputs and 16

digital control inputs

› Ideal for on/o control and alarm

or status control

General Description

ZEN-RIO is a relay output and digital

input expansion which is designed for

seamless integration with the ZEN-16

control and monitoring station.

The ZEN-RIO's relays are controlled

directly by the ZEN-16's setpoints, which

are in turn easily con gured using our

user-friendly and  exible WorkBench

The digital control inputs are designed

for SCADA applications and can be read

directly from the ZEN-16's com ports.

Applications for the ZEN-RIO are nu-

merous, and include on/o control and

alarming functions.

4 CONNECTING TO YOUR ZEN-16 4.1 - Expansion terminals (see 2.1S–T) Connect your ZEN-RIO to your ZEN-16 using the sup- Expansion Out plied cable, as shown (right). The lead should be connected from the Expansion Out ZEN-16 terminal on the ZEN-16 to the Expansion In terminal Expansion In on the ZEN-RIO. CAUTION! Risk of damage to equipment: ZEN-RIO Never connect an expansion terminal on a ZEN-16 or ZEN-RIO to an Ethernet port, network, or any other unapproved device.

Relay Outputs 1-16 The ZEN-RIO's 16 relay outputs are controlled by the ZEN-16's 16 setpoints, and are configured from the Setpoints tab. The image below shows the setup page for Setpoint 1 in WorkBench. The output of Setpoint 1 is directly mapped to Relay 1 in the ZEN-RIO, if connected.
PAGE 9
Control Inputs 1-16 The 16 digital control inputs on the ZEN-RIO are intended for use with SCADA systems or various plugins supplied by Define Instruments. Without a plugin they do not have any associated control functions on their own. The status of the 16 digital control inputs can be read from any of the ZEN-16's serial ports when set to Modbus RTU slave mode (factory default).
