Mounting

Dimensions

Panel Mounting

Before you begin, note that the

mounting panel cannot be more than

5mm thick.

1. Make a panel cut-out measuring

92 x 92 mm (3.622” x 3.622”).

2. Slide the controller into the cut-

out, ensuring that the rubber seal

is in place.

3. Push the 2 mounting brackets

into their slots on the sides of the

controller as shown in the figure

to the right.

4. Tighten the bracket 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

figure to the right.

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 26-12 AWG wire (0.13 mm 2–3.31 mm2):

1. Strip the wire to a length of 7±0.5mm (0.250–0.300 inches).

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 input 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

This model comprises a total of 22 inputs and 16 transistor outputs. Input functionality can be

adapted as follows:

1. 22 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 14 and 15 can function as either digital or analog inputs.

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

or as normal digital inputs.

-Inputs 1 and 3 can function as either counter reset, as normal digital inputs, or as part of a shaft-

encoder.

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

normal digital inputs.

Input Jumper Settings

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 9.

Incompatible jumper settings and wiring connections may seriously damage the controller.

Power Supply

The controller requires an external 24VDC power supply.

Anon-isolated power supply can be used if a 0V signal is connected to the chassis.

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 Power Supply

To maximize system performance, avoid electromagnetic interference by:

Mounting the controller on a metal panel.

Earthing the controller’s power supply: connect one end of a 14 AWG wire to the chassis

signal; connect the other end to the panel.

Note: If possible, the wire used to earth the power supply should not exceed 10 cm in length.

However, it is recommended to earth the controller in all cases.

Communication Port

Turn off power before making communications connections.

Caution

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

Always use the appropriate port adapters.

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

device, avoid potential voltage that exceeds ± 10V.

Port 1 is type RJ-11 and may be set to either RS232 or RS485 via jumper as shown below.

By factory default, the port is set to RS232, termination ON.

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.

To connect a PC to a port that is set to RS485, remove the RS485 connector, and connect the PC to

the PLC via the programming cable. Note that this is possible only if flow control signals are not used

(which is the standard case).

*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.

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

1. The I/O board of the controller is now exposed, enabling you to change I/O settings according to

the jumpers shown on page 5.

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. Jumper

settings are shown on page 8.

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.
