Description
The ABB RTD0003 is a specialized plug-in hardware module designed primarily for use within ABB’s Relion protection and control relay families (such as the REM620 motor protection IEDs). It provides precise temperature monitoring capabilities via Resistance Temperature Detectors (RTDs) to protect critical electrical assets like motor windings, transformers, and bearings from thermal overload.

Engineering and Field Deployment Notes
When integrating the RTD0003 module into existing protection IEDs during retrofits or new panel builds, adhere to standard instrumentation practices to ensure measurement accuracy.
Integration and Compatibility
- Slot Allocation: Ensure the host IED has the physical slot available (commonly slot X105 on REM620 units). Inserting or removing option modules must be done with auxiliary control power de-energized to prevent internal bus errors.
- Sensor Shielding: Use twisted, shielded pair cables for all field-run RTD inputs. Ground the shield at one end only (typically the panel ground bar) to minimize electromagnetic interference (EMI) from adjacent medium-voltage VFD cables or high-current busbars.
- Configuration Tooling: The host IED must be configured using ABB PCM600 (Protection and Control IED Manager) to map the physical inputs of the RTD0003 to internal thermal protection logic, alarms, and trip matrices.
Frequently Asked Questions
Which ABB protection relays support the RTD0003 module?
It is primarily utilized within the ABB Relion modular protection and control product lines, such as the REM620 motor management relays. Always check the specific ordering code and hardware compatibility list of your base IED.
Does the module supply excitation current for the RTDs?
Yes, the module provides the necessary constant current source excitation required to measure resistance changes across Pt100 or equivalent elements without introducing self-heating measurement errors.
What configuration software is required to enable the module?
You must use ABB PCM600 to configure the hardware parameters, set alarm/trip thresholds for temperature monitoring, and assign logical outputs.
