EXF-RC15 Installation Guide
 Before using this product, the user must read and understand this document.
 All examples and diagrams are intended to aid understanding, and do not guarantee operation.
Unitronics accepts no responsibility for actual use of this product based on these examples.
 Please dispose of this product according to local and national standards and regulations.
 Only qualified service personnel should open this device or carry out repairs.
Failure to comply with appropriate safety guidelines can cause severe injury or property damage.
 Do not attempt to use this device with parameters that exceed permissible levels.
 Do not connect/disconnect the device when power is on.
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, in accordance
with the standards given in the product’s technical specification sheet.
 Do not place in water or let water leak onto the model.
 Do not allow debris to fall inside the model during installation.
 Ventilation: 10mm space required between model’s top/bottom edges & enclosure walls.
 Install at maximum distance from high-voltage cables and power equipment.
DIN-rail Mounting
1. Snap the model onto the DIN rail as shown in
the figure to the right.
2. When properly mounted, the model is squarely
situated on the DIN-rail as shown in the figure
to the right.
Setting the Unit ID Number
The module’s CANbus Unit ID is defined by a specific System Integer that is dedicated for
this purpose. Please refer to the Help Manual of the Visilogic software for detailed
explanation and setup instructions.

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.
 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
Caution
to break.
 Install at maximum distance from high-voltage cables and power equipment.
Wiring Procedure
Use crimp terminals for wiring; use 3.31 mm² –0.13 mm² wire (12-16 AWG):
1. Strip the wire to a length of 7±0.5mm (0.275±0.020“).
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 model and I/O signals must be connected to the same 0V signal.
I/Os
This model comprises a total of 9 digital inputs, 2 relay outputs and 4 npn (sink) outputs. Input
functionality can be adapted as follows:
1. The digital inputs may be wired, in one group, and set to either npn or pnp via wiring.
In addition, according to appropriate wiring:
- 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 and 4 are set as high-speed counters (without reset), inputs 1, 3 and 5
can function as normal digital inputs.

Relay Outputs
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
Power Supply
The model requires an external 24VDC power supply.
 The power supply must include double insulation. Outputs must be rated as
SELV/PELV/Class 2/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 nonconformity to voltage power supply specifications,
connect the device to a regulated power supply.
Earthing the model
To maximize system performance, avoid electromagnetic interference by:
 Mounting the model on a metal panel.
 Connect each common and ground connection directly to the earth ground of your system.
For ground wiring use the shortest and thickest possible wire.

Communication Port
 Turn off power before making communications connections.
USB Device
Use for application download and direct PC-EXF-RC15 communication.
CANbus
Use the CANbus port for all CANbus communications including integration. The EXF-RC15 is
shipped with a 5 pin CANbus terminal block.
CANbus Wiring
Use twisted-pair cable. DeviceNet® thick shielded twisted pair cable is recommended.
Network terminators: These are supplied with the model. Place terminators at each end of the
CANbus network.
Resistance must be set to 1%, 121Ω, 1/4W.
Connect ground signal to the earth at only one point, near the power supply.
 The network power supply need not be at the end of the network.

Notes:
1. Input functionality can be adapted as follows:
9 inputs may be used as digital inputs. They may be wired, in one group, and set to either
npn or pnp via wiring.
In addition, according to appropriate wiring:
- 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, and 4 are set as high-speed counters (without reset), inputs 1, 3 and 5
can function as normal digital inputs.
2. If you configure an input as high-speed, you can use an end-device that comprises push-pull
drive type. In this case, the high-speed input voltage ratings for npn/pnp apply.
