Symbol Meaning Description
Danger The identified danger causes physical
and property damage.
Warning The identified danger can cause
physical and property damage.
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. Caution Caution Use caution.
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.
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

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.
npn (sink) pnp (source)
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.

Analog / PT100 / TC Inputs
Each input may be set as either analog, RTD, or thermocouple. To set an input:
-Use the appropriate wiring as shown below.
-Open the device and set the jumpers according to the instructions beginning on page 8.
Shields should be connected at the signal source.
In order to function correctly, the analog power supplies must be wired as shown on page 5.
To ensure proper performance, a warm-up period of a half an hour is recommended.
Analog Inputs
Inputs may be wired to work with either current or voltage.
When set to current/voltage, all inputs share a common ACM signal.

Changing Jumper Settings
To access the jumpers, you must remove the snap-in I/O module from the controller, and then remove the
module’s PCB board. Before you begin, turn off the power supply, disconnect and dismount the controller.
Before performing these actions, touch a grounded object to discharge any
electrostatic charge.
Avoid touching the PCB board directly by holding the PCB board by its connectors.
Accessing the Jumpers
First, remove the snap-in module.
1. Locate the 4 buttons on the sides
of the module, two on either side.
Press the 2 buttons on either side
of the module as shown, and hold
them down to open the locking
mechanism.
2. Gently rock the module from side
to side, easing the module from the
controller.
3. Using a Philips
screwdriver, remove the
center screw, shown in
the figure below, from
the module’s upper PCB
board. Do not remove
any other screws.
4. Holding the PCB board by its
edges, gently lift it out of the
module.
