Mounting

Dimensions

Panel Mounting
Before you begin, note that the mounting panel cannot be more than 5 mm thick.

UL listed models:
To meet the UL508 standard, panel-mount the device on the flat surface of a Type 1 enclosure.

1. Make a panel cut-out of the appropriate size:
   ▪ SM35: 92x92mm (3.622”x3.622”).
   ▪ SM43: 122.5×91.5mm (4.82”x3.6”).
   ▪ SM70: 193x125mm (7.59”x4.92”).
2. Slide the controller into the cut-out, ensuring that the rubber seal is in place.
3. Push the mounting brackets into their slots on the sides of the panel as shown in the figure below.
4. Tighten the bracket’s screws against the panel. Hold the bracket securely against the unit while tightening the screw. The torque required is 0.35 N·m (3.1 in-lb).
5. When properly mounted, the controller is squarely situated in the panel cut-out as shown in the accompanying figures.

SM43 

SM70 

Caution 

▪ Do not apply torque exceeding 0.35 N·m (3.1 in-lb) of torque to tighten the
▪ bracket screws. Using excessive force to tighten the screw can damage this product.

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 to break.

Caution 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 (12-26 AWG):

1. Strip the wire to a length of 7±0.5mm (0.270–0.300“).
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 controller and I/O signals must be connected to the same 0V signal.

I/Os

SM35/43/70-J-TA22 models comprise a total 12 inputs, 8 digital outputs and 2 analog outputs.
Input functionality can be adapted as follows:
All 12 inputs may be used as digital inputs. They may be wired in a group via a single jumper as either npn or pnp.
In addition, according to jumper settings and appropriate wiring:

• Inputs 5 and 6 can function as either digital or analog inputs.
• Input 0 can function as a high-speed counter, as part of a shaft-encoder, or as a normal digital input.
• Input 1 can function as either a counter reset, normal digital input, or as part of a shaft-encoder.
• If input 0 is set as a high-speed counter (without reset), input 1 can function as a normal digital input.
• Inputs 7-8 and 9-10 can function as digital, thermocouple, or PT100 inputs; Input 11 can also serve as the CM signal for PT100.

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 on page 11.
Incompatible jumper settings and wiring connections may seriously damage the controller.

*Default settings

npn (sink) Input

pnp (source) Input 

Shaft-encoder 

Analog Input 

▪ Shields should be connected at the signal’s source.
▪ The 0V signal of the analog input must be connected to the controller’s 0V.

Thermocouple 

• Thermocouple 0: use Input 9 as negative input and 10 as positive.
• Thermocouple 1: use Input 7 as negative input and 8 as positive.

RTD 

▪ PT100 (Sensor 0): use Input 9 and 10, related to CM signal.
▪ PT100 (Sensor 1): use Input 7 and 8, related to CM signal.
▪ 4 wire PT100 can be used by leaving one of the sensor leads unconnected.

▪ The 0V signals of the transistor and the analog outputs must be connected to the controller’s 0V.
▪ Outputs 0 to 4 can be used as PWM outputs.

Power Supply

The controller requires an external 24VDC power supply. 

• The power supply must include double insulation. Outputs must be rated as SELV/PELV/Class2/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 non-conformity to voltage power supply specifications, connect the device to a regulated power supply.

Earthing the PLC+HMI
To maximize system performance, avoid electromagnetic interference by:

• Mounting the controller on a metal panel.
• Connect each common and ground connection directly to the earth ground of your system.
• For ground wiring uses the shortest and thickest possible wire.

Communication Port 

▪ Turn off power before making communications connections.
▪ Always use the appropriate port adapters.

SM43/SM70-J-TA22
This series comprises a USB port.
Caution The USB port in SM43 Series is not isolated. Make sure that the PC and the controller are grounded to same potential.
The USB port may be used for programming, OS download and PC access.

Pinouts
The pinouts below show the PLC port signals.

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, disconnects, and dismounts 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 

The I/O board of the controller is now exposed, enabling you to change
I/O settings (module dependent) according to the jumpers setting above.
Note: Photo is for illustration purposes only. (Using SM70)

Closing the Controller
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.

Notes: 

1. This model comprises a total of 12 inputs.
   All 12 inputs may be used as digital inputs. They may be wired in a group via a single jumper as either npn or pnp.
   In addition, according to jumper settings and appropriate wiring:
   • Inputs 5 and 6 can function as either digital or analog inputs.
   • Input 0 can function as a high-speed counter, as part of a shaft-encoder, or as normal digital inputs.
   • Input 1 can function as either counter reset, normal digital input, or as part of a shaft-encoder.
   • If input 0 is set as a high-speed counter (without reset), input 1 can function as a normal digital input.
   • Inputs 7-8 and 9-10 can function as digital, thermocouple, or PT100 inputs; input 11 can also serve as the CM signal for PT100.
2. pnp/npn maximum frequency is at 24VDC.

Notes:

1. Conversion times are accumulative and depend on the total number of analog inputs configured.
   For example, if only one analog input (fast mode) is configured, the conversion time will be 30ms; however, if two analog (normal mode) and two RTD inputs are configured, the conversion time will be 100ms + 100ms + 300ms + 300ms = 800ms.
2. The analog value can indicate faults as shown below:

Notes: The device can also measure voltage within the range of -5 to 56mV, at a resolution of 0.01mV.
The device can also measure raw value frequency at a resolution of 14-bits (16384). Input ranges are shown in the following table:

Digital Outputs 

Notes: Outputs 0 to 4 can be used as PWM outputs.

Analog Outputs 

Notes: Note that the range of each I/O is defined by wiring, jumper settings, and within the controller’s software.
