Configured for precision temperature data acquisition in Modicon Quantum automation platforms, the Schneider Electric 140ARI03010 (140ARI03010 Analog Input Module) provides direct physical electrical execution for 8 differential temperature probe inputs.

Technical Model Matrix

The 140ARI03010 is an 8-channel analog input module designed for temperature sensing via RTD probes. It supports Pt100, Pt200, Pt500, Pt1000 and Ni100, Ni200, Ni500, Ni1000 sensors, utilizing 13-bit resolution to process thermal signals across multiple range settings.

Hardware Specifications

System Integration and Communication

The Quantum platform architecture relies on standardized backplane communication for module polling and data updates. The 140ARI03010 requires 9 input words for register mapping within the PLC memory. Bus communication velocity is consistent with the Quantum backplane timing, and firmware compatibility should be verified within the Unity Pro or EcoStruxure Control Expert environments to ensure correct hardware configuration of the thermal scanning cycle.

Ordering Info

• 1 x 140ARI03010 Analog input module

• 1 x Technical installation instruction

• Note: Field terminal connectors are required for external wiring and are typically supplied with the associated mounting base.

Field Installation Guidelines

• Mounting: Ensure the module is fully seated into the Quantum backplane rack. Secure the locking mechanism to maintain electrical contact and structural stability.

• Shielding: Connect probe shields to the designated chassis ground terminal on the terminal block to prevent electromagnetic interference.

• Wiring: Maintain consistent cable lengths between probe types; use 3-wire configurations for leads exceeding 5 m to compensate for line resistance variations.

• Environment: Verify the local ambient temperature does not exceed 60 deg C and ensure the installation site is free from corrosive gasses or excessive dust accumulation.

Frequently Asked Questions

• Q: Does this module support hot-swapping?

  A: No, the 140ARI03010 does not support hot-swapping. The rack power must be cycled off before extracting or inserting the module to prevent electrical damage to the backplane pins.

• Q: How are broken wires detected?

  A: The module internal logic monitors the loop integrity. If an open circuit occurs, the channel status LED indicates a fault, and the diagnostic register is updated.

• Q: Is the input isolated from the backplane?

  A: Yes, the module provides 1780 VAC isolation between the input channels and the internal bus.

• Q: Can I mix Pt100 and Ni100 probes on the same module?

  A: Yes, channels are independently configurable for specific sensor types through the software configuration menu.

• Q: What is the update time for 3-wire measurements?

  A: The module provides an update time of 1200 ms for 3-wire probe configurations.

• Q: Is external power required for the probes?

  A: No, the module provides the necessary excitation current (0.5 mA or 2.5 mA) internally for the connected RTD sensors.

• Q: How many words are consumed in the PLC memory?

  A: The module requires 9 input words for data and status reporting.

• Q: What does the red fault LED indicate?

  A: A red fault LED signals either a broken wire (open circuit), an out-of-range signal, or a hardware failure detected by the internal self-diagnostic routines.
