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: 92x92 mm (3.622”x3.622”).
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.
DIN-rail Mounting
1. Snap the controller onto the DIN rail as
shown in the figure to the right.
2. When properly mounted, the controller is
squarely situated on the DIN-rail as
shown in the figure to the right.

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
V350-35-TU24/V350-J-TU24 models comprise a total 12 inputs, 12 digital outputs.
Input functionality can be adapted as follows:
All 12 inputs may be used as digital inputs. They may be wired in a group via a single jumper
as either npn or pnp.
In addition, according to jumper settings and appropriate wiring:
- Inputs 5 and 6 can function as either digital or analog inputs.
- Input 0 can function as a high-speed counter, as part of a shaft-encoder, or as a normal
digital input.
- Input 1 can function as either a counter reset, normal digital input, or as part of a
shaft-encoder.
- If input 0 is set as a high-speed counter (without reset), input 1 can function
as a normal digital input.
- Inputs 7-8 and 9-10 can function as digital, thermocouple, or PT100 inputs; Input 11 can also
serve as the CM signal for PT100.

Transistor Outputs (pnp)
The 0V signals of the transistor and the analog outputs must be connected to the controller’s 0V.
Outputs 1 to 6 can be used as PWM outputs.
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 PLC+HMI
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
V350-35-TU24/V350-J-TU24 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.

* 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).
Setting RS232/RS485 Communication Parameters
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 10.

USB Port
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.
Opening the Controller
Before performing these actions, touch a grounded object to discharge any electrostatic charge.
Avoid touching the PCB board directly. Hold the PCB board by its connectors.
1. Turn off the power supply, disconnect, and dismount the controller.
2. The back cover of the controller comprises 4 screws, located in the corners.
Remove the screws, and pull off the back cover.
Changing I/O Settings
After opening the controller and exposing the I/O board, you can change the jumper settings according
to the table shown above.
Changing Communication Settings
1. To access the communication jumpers, hold the I/O PCB board by its top and bottom connectors
and steadily pull the board off.
2. Locate the jumpers, and then change the settings as required, according to the jumpers’ settings
shown on page 9.
Closing the Controller
1. Gently replace the board. Make certain that the pins fit correctly into their matching receptacle.
Do not force the board into place; doing so may damage the controller.
2. Replace the back cover of the controller and fasten the corner screws.
Note that you must replace the back cover securely before powering up the controller.
