TM5SAO4L Modicon TM5 Analog Output Module 4AO ±10V 0–20mA 12-Bit

The TM5SAO4L is a Modicon TM5 analog output module with four independently configurable output channels.

Each channel can be configured for either -10 to +10 V DC voltage output or 0–20 mA current output. This allows one module to control several analog devices without using separate voltage and current output modules.

Its main advantage is four-channel analog output density with 12-bit conversion, making it suitable for standard speed references, valve positioning and process setpoint control.

The physical wiring must match the selected voltage or current configuration. Incorrect configuration can damage the module.

Key Features

• Four analog output channels
• ±10 V voltage output
• 0–20 mA current output
• Voltage and current channels can be mixed
• 12-bit conversion
• Maximum 1 ms response
• Differential outputs
• Output current limiting

Typical Applications

• Variable-speed drive references
• Proportional valve control
• Damper positioning
• Process setpoints
• Analog actuator commands

Four Independently Configurable Outputs

TM5SAO4L provides four analog output channels.

Each channel can be configured separately as:

• -10 to +10 V DC
• 0–20 mA

A mixed configuration can therefore use voltage outputs and current outputs within the same module.

Voltage Output Mode

Output Range

-10 to +10 V DC

Resolution

12-Bit Plus Sign

Resolution Value

4.882 mV

Minimum Load Impedance

1 kOhm

Voltage mode is commonly used for drive speed references, positioning devices and compatible analog controllers.

Current Output Mode

Output Range

0–20 mA

Resolution

12-Bit

Resolution Value

9.766 µA

Permitted Load

200–500 Ohm

The module does not provide a separate native 4–20 mA range. A controller program may limit the command within the 0–20 mA range when a connected device requires 4–20 mA operation.

Response Performance

Sampling Duration

300 µs for all four outputs

Response to Output Change

1 ms maximum

This performance is suitable for normal machine and process setpoint control. It is not intended for servo feedback or high-frequency waveform generation.

Output Protection

The analog outputs include short-circuit current limiting at approximately 40 mA.

The cause of a short circuit must still be corrected before normal operation is restored.

The outputs are not isolated from one another.

Wiring Requirements

Shielded, properly grounded cable is required for analog output signals.

Analog cables should be routed separately from:

• Motor power cables
• Contactor wiring
• Heater circuits
• Variable-frequency drive output cables
• High-current conductors

The software channel type must match the physical voltage or current wiring.

FAQ

Q1: What is TM5SAO4L?

A1: It is a four-channel Modicon TM5 analog output module for ±10 V or 0–20 mA signals.

Q2: Can each channel use a different signal type?

A2: Yes. The four channels can be configured individually for voltage or current output.

Q3: Does it provide native 4–20 mA output?

A3: Its specified current range is 0–20 mA. A controller program can restrict the command to the 4–20 mA portion when required.

Q4: What is the output resolution?

A4: Voltage output uses 12-bit plus sign, while current output uses 12-bit resolution.

Q5: What is the maximum response time?

A5: The response to an output change is no more than 1 ms.

Q6: Are the four outputs individually isolated?

A6: No. The output channels are not isolated from one another.

Q7: What distinguishes it from TM5SAO4H?

A7: Both provide four ±10 V or 0–20 mA outputs, but TM5SAO4H uses 16-bit resolution while TM5SAO4L uses 12-bit resolution.

Q8: Which terminal block is required?

A8: The specified terminal block is TM5ACTB12.
