Description
‑ Power Supply: Powered by REG216 rack back‑plane bus (5 VDC, 24 VDC)
‑ Power Consumption: ≤ 7 W
‑ Mechanical Structure: 6U Eurocard rack‑mount plug‑in board, metal front panel, back‑plane parallel bus connector
‑ On‑board Resources: Back‑plane bus logic, serial communication transceiver circuit, protocol processing logic, self‑diagnosis unit
‑ Communication Interface: Front‑panel serial communication ports, internal B448C parallel back‑plane bus
‑ Galvanic Isolation: External serial communication ports are electrically isolated from system internal bus
‑ Interfaces: Front‑panel serial communication connectors, back‑plane system bus connector
‑ Status LED Indicators: Power, Run, Fault, Communication‑activity LEDs
‑ Weight: Approx 0.43 kg
‑ Gateway function between internal B448C parallel back‑plane bus and external serial communication links.
‑ Transmits protection events, alarm records, measured analogue values, binary status signals from REG216 system to upper‑level SCADA and HMI workstations.
‑ Receives remote commands: protection parameter setting, function enable/disable, control commands issued by upper‑level host system.
‑ Supports time‑synchronization signal processing for protection event time‑stamping.
‑ Hardware self‑diagnosis detects power‑supply abnormality, back‑plane bus failure and communication circuit faults, and reports fault status to main CPU.
‑ Communication protocol parameters are configured by upper‑level system software; no local keypad operation.
‑ Cannot operate independently without REG216 rack back‑plane and CPU unit. Cannot be directly hardware interchanged with other REG216 I/O modules.
‑ Continuously monitors module power, back‑plane bus link status and external communication channel health. Detected faults activate fault LED and send fault word to system CPU.
‑ No local numerical display; communication status, event logs and fault codes are read via upper‑level HMI workstation.
‑ Module hardware failure will cut off external communication link. Local protection logic still runs normally, but remote monitoring, remote setting and event uploading are lost.
‑ Back‑plane connector: Connect to REG216 B448C parallel back‑plane bus for data exchange with CPU and other plug‑in modules.
‑ Front‑panel serial connectors: Physical link for external host‑system communication.
‑ 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)
- 216MB66 module (HESG324510M1)
Complementary parts: REG216 system rack and back‑plane, 216VC62a CPU processing unit, upper‑level SCADA workstation, shielded serial communication cables.
‑ Power off the whole rack before inserting or removing the module. Communication field wiring adopts shielded cables with single‑end shield grounding to reduce electromagnetic interference.
‑ For spare‑part replacement: Verify complete part number HESG324510M1. After replacement, confirm back‑plane bus identification, verify communication link establishment, event upload and remote parameter access function.
‑ Module hardware fault results in loss of remote communication, while local protection functions keep working.
Generator and main‑transformer protection cabinets in thermal / hydro power plants; ABB REG216 numerical generator‑transformer protection‑control system; industrial spare‑part replacement.
- REG216 dedicated rack‑mount communication gateway module, realizes data exchange between internal parallel bus and external host system.
- Supports uploading protection events, alarms, measured values and receiving remote configuration commands.
- Comprehensive hardware self‑diagnosis for power supply, bus and communication circuit faults.
- Front‑panel LED indicators for power, run, fault and communication activity status.
- Standard Eurocard mechanical structure, convenient installation and maintenance.
