ABB 500MTM02 1MRK001967-AA Multi‑Function Terminal Module

‑ Power Supply: Powered by Procontrol P13 rack back‑plane bus; field side 24 VDC / analog process signal

‑ Power Consumption: approx 4.2 W

‑ Mechanical Structure: Eurocard plug‑in board for Procontrol P13 rack, metal front panel, back‑plane bus connector, large‑capacity field signal terminal block

‑ On‑board Resources: signal distribution circuit, surge‑suppression protection components, filter circuit, loop‑fault sampling circuit, back‑plane bus interface, module self‑diagnosis unit

‑ Communication Interface: Internal dedicated local back‑plane bus for matched I/O functional module

‑ Galvanic Isolation: Galvanic isolation between field wiring terminals and rack internal logic bus, isolation rating 2500 VAC

‑ Supported Signal Types: binary 24 VDC switch signal, 4‑20 mA analog current signal, 0‑10 V analog voltage signal

‑ Status LED Indicators: Power indicator, Module Fault indicator

‑ Weight: approx 0.88 kg

‑ Provides centralized wiring terminals for matched I/O modules, completes transition connection between field site cables and internal I/O circuit boards.

‑ Built‑in surge‑suppression and filter circuit, restrains surge pulse and high‑frequency interference introduced by field cables, protects internal I/O channel circuits.

‑ Realizes signal distribution and impedance matching for binary and analog process signals.

‑ Supports signal‑loop fault sampling detection, transmits wiring‑loop abnormal status to the paired I/O functional module.

‑ Module self‑diagnosis monitors back‑plane bus connection and power‑supply abnormal state, uploads module‑level fault‑alarm information.

‑ Cannot run independently; must be installed and used together with corresponding I/O functional modules inside Procontrol P13 rack. 1MRK001967‑AA is hardware revision variant of 500MTM02 series; pin‑compatible within 500MTM02 revision family, cannot directly interchange with other types of terminal modules.

‑ Continuously monitors module power‑supply and back‑plane bus connection status. Detected faults activate fault LED and send fault word to main processor.

‑ No local numerical display; terminal‑module fault information is read via commissioning software or upper‑level HMI workstation.

‑ Module hardware failure will cause signal‑access abnormality of matched I/O channels; rack internal control‑logic operation keeps normal.

‑ Back‑plane connector: connects to Procontrol P13 internal local bus for signal interaction with matched I/O module.

‑ Field signal terminal block: wiring terminals for field sensors, contact and actuator cables.

‑ Mounting: Plug‑in installation inside Procontrol P13 system rack

‑ Operating Temperature: ‑20 °C ~ +60 °C

‑ Storage Temperature: −40 °C ~ +70 °C

‑ Relative Humidity: 5‑95 %RH, non‑condensing

‑ Protection Class: IP20 (cabinet internal)

‑ Power off the whole rack before inserting or removing this terminal module. Field wiring adopts shielded cables with single‑end shield grounding; strictly separate binary and analog signal wiring.

‑ For spare‑part replacement: Verify complete part number 1MRK001967‑AA, confirm matching with corresponding I/O module. After replacement, confirm back‑plane bus identification, verify signal‑loop access and fault‑reporting function. Mismatched terminal module will result in abnormal signal processing.

‑ Module hardware fault will lead to access failure of associated I/O signal channels.
