defined by the European directives for machinery, low voltage, and EMC. Only a technician or engineer trained
in the local and national electrical standards should perform tasks associated with the device’s electrical wiring.
Symbols are used to highlight
information relating to the user’s
personal safety and equipment
protection throughout this document.
When these symbols appear, the
associated information must be read
carefully and understood fully.
Failure to comply with appropriate safety guidelines can result in severe personal
injury or property damage. Always exercise proper caution when working with
electrical equipment.
Check the user program before running it.
Do not attempt to use this device with parameters that exceed permissible levels.
Install an external circuit breaker and take appropriate safety measures against short-
circuiting in external wiring.
To avoid damaging the system, do not connect / disconnect the device when the
power is on.
Caution
Ascertain that terminal blocks are properly secured in place.

Warning
Caution Caution Use caution.
The identified danger causes physical
and property damage.
The identified danger can cause
physical and property damage.
Environmental Considerations
Do not install in areas with: excessive or conductive dust, corrosive or flammable gas,
moisture or rain, excessive heat, regular impact shocks or excessive vibration.
Provide proper ventilation by leaving at least 10mm of space between the top and
bottom edges of the device and the enclosure walls.
Do not place in water or let water leak onto the unit.
Do not allow debris to fall inside the unit during installation.

Wiring
Do not touch live wires.
Unused pins should not be connected. Ignoring this directive may damage the
device.
Do not connect the ‘Neutral’ or ‘Line’ signal of the 110/220VAC to the device’s 0V pin.
Double-check all wiring before turning on the power supply.
Wiring Procedures
Use crimp terminals for wiring; use 26-12 AWG wire (0.13 mm 2–3.31 mm2) for all wiring purposes.
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 that a proper connection can be
made.
4. Tighten enough to keep the wire from pulling free.
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 other substance on stripped wire that might cause the wire strand to
break.
Install at maximum distance from high-voltage cables and power equipment.
I/O Wiring—General
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.
Digital Inputs
Each group of 9 inputs has a common signal. Each group can be used as either pnp (source) or npn (sink),
when appropriately wired as shown in the following figures.
Inputs I0 and I2 can be used as normal digital inputs, as high-speed counters, or as part of a shaft encoder.
Inputs I1 and I3 can be used as normal digital inputs, as high-speed counter resets, or as part of a shaft
encoder.

Digital Outputs
Wiring Power Supplies
Use a 24VDC power supply for both relay and
transistor outputs.
1. Connect the "positive" lead to the "V1"
terminal, and the “negative” lead to the "0V"
terminal.
In the event of voltage fluctuations or non-
conformity to voltage power supply
specifications, connect the device to a regulated
power supply
Relay Outputs
Each output can be wired
separately to either AC or DC
as show below.
The 0V signal of the relay
outputs is isolated from the
controller’s 0V signal.
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.

Transistor Outputs
Each output can function as either npn or pnp, in accordance with jumper settings and wiring. Open the
device and set the jumpers according to the instructions beginning on page 8.
The 0V signal of the transistor outputs is isolated from the controller’s 0V signal.

Analog I/O Power Supplies
Use a 24VDC power supply for all analog input and output modes.
1. Connect the "positive" cable to the "V2" terminal, and the “negative” to the "0V" terminal.
In the event of voltage fluctuations or non-conformity to voltage power supply specifications, connect the
device to a regulated power supply.
Since the analog I/O power supply is isolated, the controller’s 24VDC power supply may also be used to
power the analog I/Os.
The 24VDC power supply must be turned on and off simultaneously with the controller’s
power supply.
