Description
‑ Power Supply: Powered by REG216 rack back‑plane bus (5 VDC, 24 VDC)
‑ Power Consumption: ≤ 10 W
‑ Mechanical Structure: 6U Eurocard rack‑mount plug‑in board, metal front panel, back‑plane parallel bus connector
‑ On‑board Resources: Analogue signal conditioning circuit, multi‑channel high‑speed A/D converter, data pre‑processing logic, firmware EPROM, calibration‑parameter EEPROM, runtime RAM, B448C parallel back‑plane bus interface
‑ Communication Interface: Internal B448C parallel back‑plane bus, no external communication port
‑ Galvanic Isolation: Analogue input circuits are electrically isolated from system internal bus
‑ Interfaces: Front‑panel analogue signal connector, back‑plane system bus connector
‑ Status LED Indicators: Power, Run, Module Fault LEDs
‑ Weight: Approx 0.47 kg
‑ Receives conditioned measurement signals from 216GW61 transformer modules for AC current, AC voltage and auxiliary analogue variables.
‑ Performs high‑speed synchronous sampling and A/D conversion for multi‑channel power‑system analogue quantities.
‑ Implements digital filtering and pre‑processing of sampled data, transmits digital measurement values to system CPU over B448C parallel bus for protection logic, metering and monitoring functions.
‑ Stores factory calibration and offset parameters in on‑board EEPROM memory.
‑ Hardware self‑diagnosis covers power‑supply abnormality, A/D conversion failure, firmware check‑sum error and internal circuit faults, and reports fault status to main CPU.
‑ Sampling rate, filter parameters and calibration values are configured by upper‑level system software; no local keypad operation.
‑ Cannot work independently without REG216 rack back‑plane, CPU unit and matching 216GW61 instrument transformer modules. This hardware revision E is pin‑compatible with other 216EA62 revisions, with internal component upgrades for improved EMC performance. Not directly hardware interchangeable with other REG216 series modules.
‑ Continuously monitors analogue input channels, module power supply, A/D conversion and internal hardware status. Detected faults activate fault LED and send fault word to system CPU.
‑ No local numerical display; measured values and fault codes are retrieved via upper‑level HMI workstation.
‑ Module hardware failure leads to complete loss of analogue measurement acquisition. Protection functions based on current and voltage quantities cannot work normally, which brings serious safety risks for generator‑transformer set.
‑ Back‑plane connector: Connects to B448C parallel back‑plane bus for data exchange with CPU and other plug‑in modules.
‑ Front‑panel field connector: Receives conditioned analogue signals from 216GW61 instrument transformer modules.
‑ Mounting: Plug‑in installation inside REG216 system rack
‑ Operating Temperature: 0 °C ~ +60 °C
‑ Storage Temperature: −40 °C ~ +85 °C
‑ Relative Humidity: 5‑95 %RH, non‑condensing
‑ Protection Class: IP20 (inside cabinet)

Complementary parts: REG216 system rack and back‑plane, 216VC62a CPU processing unit, 216GW61 input transformer module, field shielded signal cables.
‑ Power off the entire rack before inserting or removing the module. Analogue signal wiring must adopt shielded cables with single‑end shield grounding to suppress electromagnetic interference.
‑ For spare‑part replacement: Verify full part number 1MRB178066R1E. After replacement, confirm back‑plane bus identification, complete calibration verification, test analogue sampling accuracy and self‑diagnosis fault‑reporting function.
‑ Module hardware fault causes loss of all analogue measurement data and disables core generator‑transformer protection functions.
Generator and main‑transformer protection cabinets in thermal / hydro power plants; ABB REG216 numerical generator‑transformer protection‑control system; industrial spare‑part replacement for older hardware revisions.
- Special‑purpose analogue input pre‑processing unit for REG216 protection system, implementing high‑precision A/D conversion for AC voltage and current measuring signals.
- Works cooperatively with 216GW61 transformer modules to complete isolation and conditioning for primary power‑system quantities. Revision E improves anti‑interference EMC performance.
- Built‑in comprehensive self‑diagnosis monitors power supply, A/D circuit and firmware status for reliable fault detection.
- Measurement data is transmitted via B448C parallel bus to main CPU for protection calculation and metering.
- Standard Eurocard rack‑mount mechanical structure, convenient for installation and maintenance, pin‑compatible with other 216EA62 hardware revisions.
