Backplane Bus Communication Velocity and Firmware Compatibility
The temperature interface module processes raw microvolt and resistance inputs from field sensors, executing 16-bit analog-to-digital conversion before transferring digital values across the system bus. Fast register updates maintain backplane bus communication velocity across expanded controller topologies. Integrated cold junction compensation and linearizing algorithms process wide temperature ranges without imposing overhead on primary control processors, maintaining strict firmware flash compatibility across standard ABB DCS module revisions.
Frequently Asked Questions
Q: Does the NTR002-A support simultaneous connection of an RTD on channel 1 and a thermocouple on channel 2?
A: Yes. Each of the two input channels operates independently, allowing configuration of individual sensor types and linearizing profiles via software parameters.
Q: How does the module handle sensor wire resistance during RTD measurements?
A: The module utilizes dedicated multi-wire terminal connections to automatically measure and compensate for field wiring resistance, preserving the baseline +/-0.1 deg C measurement accuracy.
Q: Is external power required to drive thermocouple reference junction compensation?
A: No. The internal cold junction compensation circuitry derives operational power directly through the main module backplane interface.
Field Installation Guidelines
Mount the module securely inside an IP54 or higher industrial enclosure using appropriate mounting hardware. Fasten sensor conductors to the terminal block, maintaining clear separation between low-level thermocouple/RTD wiring and high-voltage AC power cables. Route all sensor wiring through shielded twisted-pair cables, grounding the cable shield at a single cabinet earth point to eliminate common-mode ground loop noise.
