Installing / Removing the Snap-in I/O Module

Installing a Snap-in I/O Module
You can install a Snap-in I/O Module both before and after mounting the controller.

• Turn off the power before installing I/O modules.

Note: the protective cap covering the I/O connector shown in the accompanying figure. This cap must cover the connector whenever a Snap-in I/O Module is not attached to the controller. You must remove this cap before installing a module.

1. Pry the cap off using the blade of a screwdriver.
2. Line the circular guidelines on the controller up with the guidelines on the module as shown below.
3. Apply even pressure on all 4 corners until you hear a distinct ‘click’.

The module is now installed. Check that all sides and corners are correctly aligned.

Inputs I0, I1, and I2, I3 can be used as shaft encoders as shown below

Removing a Snap-in I/O Module

1. Press the buttons on the sides of the module 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. Replace the protective cap on the connector.

Wiring

• Do not touch live wires.

• This equipment is designed to operate only in SELV/PELV/Class 2/Limited Power environments.

• All power supplies in the system must include double insulation. Power supply outputs must be rated as SELV/PELV/Class
  2/Limited Power.

• Do not connect either the ‘Neutral or ‘Line’ signal of the 110/220VAC to device’s 0V pin.

• All wiring activities should be performed while power is OFF.

• Use over-current protection, such as a fuse or circuit breaker, to avoid excessive currents into the power supply connection point.

• Unused points should not be connected (unless otherwise specified). 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:

  • Controllers offering a terminal block with pitch of 5mm: 0.5 N·m (5 kgf·cm).
  • Controllers offering a terminal block with pitch of 3.81mm f 0.2 N·m (2 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

• Controllers offering a terminal block with pitch of 5mm: 26-12 AWG wire (0.13 mm2 –3.31 mm2).
• Controllers offering a terminal block with pitch of 3.81mm: 26-16 AWG wire (0.13 mm2 – 1.31 mm2).
  • Strip the wire to a length of 7±0.5mm (0.270–0.300“).
  • Unscrew the terminal to its widest position before inserting a wire.
  • Insert the wire completely into the terminal to ensure a proper connection.
  • Tighten enough to keep the wire from pulling free.

Wiring Guidelines

• Use separate wiring ducts for each of the following groups:

  • Group 1: Low voltage I/O and supply lines, communication lines.
  • Group 2: High voltage Lines, Low voltage noisy lines like motor driver outputs.
    Separate these groups by at least 10cm (4″). If this is not possible, cross the ducts at a 90˚angle.

• For proper system operation, all 0V points in the system should be connected to the system 0V supply rail.

• Product-specific documentation must be fully read and understood before performing any wiring.

Allow for voltage drop and noise interference with input lines used over an extended distance. Use wire that is properly sized for the load.

Earthing the product

To maximize system performance, avoid electromagnetic interference as follows:

• Use a metal cabinet.
• onnect the 0V and functional ground points (if exist) directly to the earth ground of the system.
• Use the shortest, less than 1m (3.3 ft.) and thickest, 2.08mm² (14AWG) min, wires possible.

Digital Inputs

• Each group of 8 inputs has two common signals. 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.
  • The common signals of each group are internally shorted on each connector.

Inputs I0, I1, and I2, I3 can be used as shaft encoders as shown below.

Digital Outputs

Wiring Power Supplies

1. Connect the “positive” lead to the “V1” terminal for the relay outputs, to the “V2” terminal for the transistor outputs.
2. In both cases, connect the “negative” lead to the “0V” terminal of each output group.
   • In the event of voltage fluctuations or non-conformity to voltage power supply specifications, connect the device to a regulated power supply.
   • Do not connect the ‘Neutral’ or ‘Line’ signal of the 110/220VAC to the device’s 0V pin.

Relay Outputs

• 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 be wired separately as either npn or pnp.
• The 0V signal of the transistor outputs is isolated from the controller’s 0V signal.

Analog Inputs

• Shields should be connected at the signal source.
• Inputs may be wired to work with either current or voltage.
• Note that the analog input’s 0V signal must be the same 0V used by the controller’s power supply.

Analog Outputs

Wiring the Analog Outputs’ Power Supply

1. Connect the “positive” cable to the “+V” terminal, and the “negative” to the “0V” terminal.
2. The analog 0V signal must be the same 0V used by the controller’s power supply.
3. A non-isolated power supply can be used provided that a 0V signal is connected to the chassis.
4. Do not connect the ‘Neutral’ or ‘Line’ signal of the 110/220VAC to the device’s 0V pin.
5. In the event of voltage fluctuations or non-conformity to voltage power supply specifications, connect the device to a regulated power supply.

WARNING: The 24VDC power supply must be turned on and off simultaneously with the controller’s power supply.

Output Wiring

• Shields should be earthed, connected to the earth of the cabinet.
• An output can be wired to either current or voltage.
• Do not use current and voltage from the same source channel.
