Panel Mounting

Before you begin, note that the mounting panel cannot be more than 5 mm thick.

UL listed models:

To meet the UL508 standard, panel-mount the device on the flat surface of a Type 1 enclosure.

1. Make a panel cut-out of the appropriate size:

V130/V350/V130J/V350J: 92x92 mm (3.622”x3.622”).

V430J: 122.5x91.5 mm (4.82”x3.6”).

2. Slide the controller into the cut-out, ensuring that the rubber seal is in place.

3. Push the mounting brackets into their slots on the sides of the panel as shown in the figure below.

4. Tighten the bracket’s screws against the panel. Hold the bracket securely against the unit while

tightening the screw.

5. When properly mounted, the controller is squarely situated in the panel cut-out as shown in the

accompanying figures.

Wiring

Do not touch live wires.

Install an external circuit breaker. Guard against short-circuiting in external wiring.

Use appropriate circuit protection devices.

Unused pins should not be connected. Ignoring this directive may damage the device.

Double-check all wiring before turning on the power supply.

Caution

To avoid damaging the wire, do not exceed a maximum torque of 0.5 N·m (5 kgf·cm).

Do not use tin, solder, or any substance on stripped wire that might cause the wire

strand to break.

Install at maximum distance from high-voltage cables and power equipment.

Wiring Procedure

Use crimp terminals for wiring; use 3.31 mm ² –0.13 mm² wire (12-16 AWG):

1. Strip the wire to a length of 7±0.5mm (0.270–0.300“).

2. Unscrew the terminal to its widest position before inserting a wire.

3. Insert the wire completely into the terminal to ensure a proper connection.

4. Tighten enough to keep the wire from pulling free.

Input or output cables should not be run through the same multi-core cable or share

the same wire.

Allow for voltage drop and noise interference with I/O lines used over an extended distance.

Use wire that is properly sized for the load.

The controller and I/O signals must be connected to the same 0V signal.

I/Os

V130/V350/V130J/V350J-TR20 models comprise a total of 12 inputs, 6 relay outputs and 2 npn

outputs.

V430J-RH2 comprises a total of 12 inputs and 6 relay outputs.

Input functionality can be adapted as follows:

12 inputs may be used as digital inputs. They may be wired in a group via a single jumper

as either npn or pnp.

According to jumper settings and appropriate wiring:

- Inputs 10 and 11 can function as either digital or analog inputs.

- Inputs 0, 2, and 4 can function as high-speed counters, as part of a shaft-encoder,

or as normal digital inputs.

- Inputs 1, 3, and 5 can function as either counter reset, as part of a shaft-encoder,

or as normal digital inputs.

- If inputs 0, 2, 4 are set as high-speed counters (without reset), inputs 1, 3, 5 can function as

normal digital inputs.

The tables below show how to set a specific jumper to change input functionality. To access the I/O

jumpers, you must open the controller according to the instructions beginning on page 11.

Increasing Contact Life Span

To increase the life span of the relay output contacts

and protect the device from potential damage by

reverse EMF, connect:

A clamping diode in parallel with each inductive

DC load

An RC snubber circuit in parallel with each

inductive AC load

npn Outputs (TR20 Only)

Power Supply

The controller requires an external 24VDC power supply.

The power supply must include double insulation. Outputs must be rated as

SELV/PELV/Class2/Limited Power.

Use separate wires to connect the functional

earth line (pin 3) and the 0V line (pin 2) to the

system earth ground.

Install an external circuit breaker. Guard

against short-circuiting in external wiring.

Double-check all wiring before turning

on the power supply.

Do not connect either the ‘Neutral’ or ‘Line’

signal of the 110/220VAC to device’s 0V pin

In the event of voltage fluctuations or non-

conformity to voltage power supply

specifications, connect the device to

a regulated power supply.

Earthing the OPLC

To maximize system performance, avoid electromagnetic interference by:

Mounting the controller on a metal panel.

Connect each common and ground connection directly to the earth ground of your system.

For ground wiring uses the shortest and thickest possible wire.

Communication

V130/V350/V130J/V350J

These models comprise a built-in RS232/RS485 serial port (Port 1)

V430J

These models comprise built-in ports: 1 USB and 1 RS232/RS485 (Port 1).

Note that physically connecting a PC to the controller via USB suspends RS232/RS485

communications via Port 1. When the PC is disconnected, RS232/RS485 resumes.

RS232/RS485 Port

Turn off power before making communications connections.

Caution Always use the appropriate port adapters.

Caution

Signals are related to the controller’s 0V; the same 0V is used by the power supply.

The serial port is not isolated. If the controller is used with a non-isolated external device,

avoid potential voltage that exceeds ± 10V.

Use RS232 to download programs from a PC, and to communicate with serial devices and

applications, such as SCADA.

Use RS485 to create a multi-drop network containing up to 32 devices.

Pinouts

The pinouts below show the PLC port signals.

RS232 RS485** Controller Port

Pin # Description Pin # Description

Pin #1

1* DTR signal 1 A signal (+)

2 0V reference 2 (RS232 signal)

3 TXD signal 3 (RS232 signal)

4 RXD signal 4 (RS232 signal)

5 0V reference 5 (RS232 signal)

6* DSR signal 6 B signal (-)

* Standard programming cables do not provide connection points for pins 1 and 6.

** When a port is adapted to RS485, Pin 1 (DTR) is used for signal A,

and Pin 6 (DSR) signal is used for signal B.

Note that it is possible to establish a PC to PLC connection using RS232 even when the PLC is set to

RS485 (this eliminates the need to open the controller to set jumpers).

To do so, remove the RS485 connector (pins 1 & 6) from the PLC and connect a standard RS232

programming cable.

Note that this is possible only if DTR and DSR signals of RS232 are not used (which is the standard

case).

Caution

The USB port is not isolated.

Make sure that the PC and the controller are grounded to same potential.

The USB port may be used for programming, OS download, and PC access.

Setting RS232/RS485 Communication Parameters, V130/V350/V130J/V350J

This port may be set to either RS232 or RS485 via jumper.

The accompanying figure shows the jumper factory

default settings.

These jumpers may be used to:

Set communications to RS485, by setting both COMM

jumpers to ‘485’.

Set RS485 termination, by setting both TERM jumpers

to ‘OFF’.

To access the jumpers, you must open the controller

according to the instructions on page 11.
