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

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

directly by the ZEN-16's setpoints, which

are in turn easily con gured using our

user-friendly and  exible WorkBench

so ware (download it for free at

de neinstruments.com/workbench).

PWR illuminates when power is connected to the unit.

BEAT will  ash every second to show that the unit is operating.

TX shows communication responses from the ZEN-RIO to the ZEN-16.

RX shows communication requests from the ZEN-16 to the ZEN-RIO.

ASP shows that the setpoint mode has been con gured correctly. This LED should

always be lit when the unit is powered on.

Relay output LEDs show the active state of relays 1–16. When the LED is o , the

respective relay is de-energised, and when the LED is on, the respective relay is ener-

gised (see 3.1 for more information).

Control input LEDs show the active state of digital control inputs 1–16. If the LED

is on, the respective digital control input has been activated (see 3.2 for more

information).

WIRING & DIP SWITCHES

3.1 - Relays 1–16 (see 2.1A–P)

The relay outputs are located along the upper

and lower le sides of the unit (see 2.1A–P),

and are wired as shown (right).

LED indicators

The Relay Outputs LED indi-

cators show the active state of each relay. If the LED is o , the respective relay is

de-energised and the COM terminal is connected to the NC terminal. If the LED

is on, the respective relay is energised and the COM terminal is switched to the

3.2 - Control inputs 1–16 (see 2.1Q & 2.1U)

The digital control inputs are located on the lower right side of the

unit (see 2.1Q). The input type for control inputs 1–16 must be set

to either NPN or PNP using DIP switch 4 (see 2.1U).

Set switch 4 to the O position for NPN, or the On position for

PNP. (Note that the 16 digital control inputs must be either all NPN

or all PNP, but could combine di erent types of sensors.)

All digital control inputs must be driven

from outputs which can sink current (i.e.

active low).

3.3 - Power (see 2.1R)

The power terminal is located on the top side of the unit, in the far

right corner (see 2.1R). The ZEN-RIO accepts 24V DC supply (±15%).

CONNECTING TO YOUR ZEN-16

4.1 - Expansion terminals (see 2.1S–T)

Connect your ZEN-RIO to

your ZEN-16 using the sup-

plied cable, as shown (right).

The lead should be connect-

ed from the Expansion Out

terminal on the ZEN-16 to

the Expansion In terminal

on the ZEN-RIO.

CAUTION! Risk of damage to equipment:

Never connect an expansion terminal on a ZEN-16 or ZEN-RIO to an Ethernet port, network, or any other unapproved device.

The ZEN-16 and ZEN-RIO are connected using a standard Cat5 patch lead, however the expansion terminals are NOT standard Ethernet ports.

ZEN-RIO

4.2 - So ware setup

So ware setup of the ZEN-RIO is facilitated through our simple and  exible De-

 ne WorkBench so ware (de neinstruments.com/workbench), connected to the

ZEN-16.

Note that De ne WorkBench does not connect directly to your ZEN-RIO - it connects

to the ZEN-16, and all options relating to the ZEN-RIO are con gured from there.

Relay Outputs 1-16

The ZEN-RIO's 16 relay outputs are controlled by the ZEN-16's 16 setpoints, and are

con gured from the Setpoints tab. The image below shows the setup page for Set-

point 1 in WorkBench. The output of Setpoint 1 is directly mapped to Relay 1 in the

ZEN-RIO, if connected.

Control Inputs 1-16

The 16 digital control inputs on the ZEN-RIO are intended for use with SCADA sys-

tems or various plugins supplied by De ne 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 se-

rial ports when set to Modbus RTU slave mode (factory default). They can either be

read as a 16 bit value from the Modbus Input register #4103 (4102 for direct address-

ing), or as Modbus discrete status inputs from input #113 to 128 (112–127 for direct

addressing).
