TM3 Analog Output Signal Characteristics

The TM3AQ2 converts controller commands into two analog output channels. Each channel can be configured for current or voltage operation. The listed LSB values are 2.44 mV for 0-10 V, 4.88 mV for -10 to 10 V, 4.88 uA for 0-20 mA and 3.91 uA for 4-20 mA.

Output-to-supply insulation is rated at 1500 V AC, while output-to-internal-logic insulation is rated at 500 V AC. The module specifies +/- 0.01 %FS non-linearity and a temperature drift of +/- 0.006 %FS/deg C.

The TM3 expansion assembly distributes data and power through the bus expansion connector. The module uses a simple interlocking assembly mechanism for connection with compatible Modicon TM3 components.

Frequently Asked Questions

Q: What output signals does the TM3AQ2 provide?
A: The module provides two analog outputs configurable for 4-20 mA, 0-20 mA, 0-10 V or -10 to 10 V operation.

Q: What load impedance is specified for the outputs?
A: The specified load impedance is 1 kOhm for voltage outputs and 300 Ohm for current outputs.

Q: What is the 24 VDC current consumption at full load?
A: The specified typical current consumption is 70 mA at 24 VDC with the outputs at full load.

Field Installation Guidelines

• Install the module on a TH35-15 or TH35-7.5 DIN rail conforming to IEC 60715, or use the specified plate/panel fixing kit.
• Use the removable screw terminal block for supply and output wiring.
• Use twisted shielded pairs for analog output wiring and keep output cables below the specified 30 m maximum length.
• Separate analog signal wiring from high-current and high-switching power conductors where practical to reduce electromagnetic coupling.
• Connect cable shields according to the control panel grounding design and maintain a consistent shielding method across the analog signal path.
• Verify the selected output mode against the receiving device input type before energizing the circuit.
• Observe the specified 1 kOhm maximum voltage-output load impedance and 300 Ohm maximum current-output load impedance.
• Confirm the controller and TM3 expansion configuration before commissioning. The module is compatible with Modicon M221, M241, M251 and M262 controllers.
• Maintain the specified ambient temperature limits according to horizontal or vertical installation orientation.
• Allow sufficient panel clearance for terminal access and module removal without applying mechanical force to the bus interconnection.
