ABB 216EA62 1MRB150083R1F Analogue Input Processing Unit

‑ Power Supply: Supplied 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.

‑ Carries out high‑speed synchronous sampling and A/D conversion for multi‑channel power‑system analogue quantities.

‑ Executes 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. 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)

‑ 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 1MRB150083R1F. 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.
