Analog Signal Interface and PLC Bus Characteristics

The TM3AM6 converts voltage and current signals between field devices and the Modicon controller through the TM3 expansion bus. Each analog input supports 4-20 mA, 0-20 mA, 0-10 V, or -10 to 10 V operation. Analog outputs provide the same four signal ranges for devices such as variable speed drives or other voltage/current-controlled equipment.

The module uses a removable terminal connection and a bus expansion connector for data and supply distribution within the TM3 assembly. Input and output circuits have separate isolation paths from the supply and internal logic. Cross talk is specified at <= 1 LSB, while the stated temperature drift is +/- 0.01 % FS/deg C.

Frequently Asked Questions

Q: What controller platforms are compatible with the TM3AM6?
A: The module is compatible with Modicon M221, M241, M251, and M262 logic controllers.

Q: What analog signal ranges can the module process?
A: Inputs and outputs support 4-20 mA, 0-20 mA, 0-10 V, and -10 to 10 V. Input resolution is 12 bits or 11 bits + sign.

Q: What are the physical mounting options?
A: The module can be mounted on TH35-15 or TH35-7.5 DIN rail conforming to IEC 60715, or on a plate/panel using the specified fixing kit.

Field Installation Guidelines

• Install the module on the specified DIN rail or panel mounting surface and engage the TM3 interlocking mechanism before connecting the expansion bus.
• Use twisted shielded pairs for analog field wiring. Keep analog cables separated from high-current power and switching conductors where practical.
• Connect cable shields according to the plant grounding scheme and avoid creating unintended ground loops.
• Verify whether each field circuit is configured for current or voltage operation before wiring the removable terminals.
• Observe the stated input overload limits and output load impedance when connecting external devices.
• Confirm the required isolation between field circuits, the 24 VDC supply, and internal controller logic.
• Maintain the specified environmental limits for temperature, humidity, altitude, vibration, and shock.
• Check the PWR LED after energization and verify the controller recognizes the TM3 expansion module before commissioning analog channels.
