Description
‑ Power Supply: Powered by Procontrol P13 rack back‑plane bus
‑ Power Consumption: approx 3.8 W
‑ Mechanical Structure: Eurocard plug‑in board for Procontrol P13 rack, metal front panel, dual back‑plane bus connectors, onboard precision termination resistor network
‑ On‑board Resources: precision impedance termination resistor network, bus signal monitoring circuit, hardware fault detection unit, back‑plane bus interface, module self‑diagnosis circuit, optimized precision resistor for R1 revision
‑ Communication Interface: Internal dedicated local back‑plane bus for rack main processor
‑ Galvanic Isolation: No external field‑side channel, internal bus signal protection
‑ Bus Termination: Matched impedance for P13 local parallel bus, eliminates signal reflection effect
‑ Status LED Indicators: Power indicator, Module Fault indicator, bus status LED
‑ Weight: approx 0.82 kg
‑ Provides accurate impedance termination for the end‑point of Procontrol P13 rack local bus, restrains signal reflection, overshoot and oscillation, ensures reliable high‑speed data communication among processor, communication boards and I/O modules.
‑ Real‑time monitors bus signal quality and module internal circuit health; detects termination circuit abnormality and bus hardware failure. R1 version improves resistor thermal stability against temperature variation.
‑ Module self‑diagnosis monitors rack power‑supply and back‑plane bus communication, uploads module‑level fault‑alarm information to main processor.
‑ Cannot run independently; must be installed at the last slot of Procontrol P13 rack local‑bus segment. 1MRB150011R1 is hardware revision variant of 500TRM02 series; pin‑compatible within 500TRM02 revision family, downward compatible with R0001 version, cannot directly interchange with other series modules.
‑ One bus segment requires one 500TRM02 termination module; improper missing installation will cause unstable communication, data loss and intermittent system faults.
‑ Continuously monitors module power‑supply and internal termination circuit health. Detected faults activate fault LED and send fault word to main processor.
‑ No local numerical display; module status and fault codes are read via commissioning software or upper‑level HMI workstation.
‑ Module hardware failure or missing installation will result in local‑bus signal reflection, leading to unstable communication of all modules on this bus segment; rack control‑logic may appear intermittent abnormal operation.
‑ Dual back‑plane connectors: connects to Procontrol P13 internal local bus, completes bus‑end impedance matching and transmits diagnostic status to main processor.
‑ Mounting: Plug‑in installation inside Procontrol P13 system rack, must be located at the final slot of bus segment
‑ Operating Temperature: ‑20 °C ~ +60 °C
‑ Storage Temperature: −40 °C ~ +70 °C
‑ Relative Humidity: 5‑95 %RH, non‑condensing
‑ Protection Class: IP20 (cabinet internal)
- 500TRM02 termination‑resistor module (1MRB150011R1)
Complementary parts: Procontrol P13 rack and back‑plane, main processor module, Procontrol P13 commissioning software.
‑ Power off the whole rack before inserting or removing this termination module. Must install on the last physical slot of corresponding local‑bus segment; do not install in middle slot arbitrarily.
‑ For spare‑part replacement: Verify complete part number 1MRB150011R1. After replacement, confirm back‑plane bus identification, verify bus communication quality and fault‑reporting function. Wrong‑type module will cause bus impedance mismatch and system communication instability.
‑ Module hardware fault will affect communication reliability of all modules on this bus segment.
