Description
‑ Power Supply: Powered by system back‑plane (5 VDC, 24 VDC)
‑ Power Consumption: ≤ 8 W
‑ Mechanical Structure: Eurocard plug‑in board, metal front panel, back‑plane bus connector
‑ On‑board Resources: Multi‑channel relay drive circuit, galvanic isolation, self‑diagnosis logic, back‑plane parallel bus interface
‑ Communication Interface: Internal back‑plane parallel bus, no external communication port
‑ Galvanic Isolation: Field output channels are electrically isolated from system internal bus
‑ Interfaces: Field wiring connector on front panel, back‑plane system bus connector
‑ Status LED Indicators: Power, Run, Fault, Channel alarm LEDs
‑ Weight: Approx 0.42 kg
‑ Multiple isolated binary relay dry‑contact outputs for external trip, interlock and alarm loads.
‑ Receive logic commands from system CPU via back‑plane bus, execute on‑off output actions.
‑ Built‑in hardware self‑diagnosis: detect power supply abnormality, drive circuit failure and module internal faults, report fault status to main CPU.
‑ Relay contact status and module fault information are uploaded to the host system through back‑plane bus for upper‑level monitoring.
‑ All configuration parameters are set by upper‑level system software, no local keypad operation.
‑ Cannot work independently without REG216 system back‑plane and CPU unit. Cannot be directly hardware interchanged with other series modules.
‑ Continuously monitor module power, internal circuit and output channel status. Hardware faults will trigger fault LED and send fault word to system.
‑ No local display. Output status and fault codes are read via upper‑level HMI.
‑ Module hardware failure will cause loss of corresponding binary output channels, protection trip and interlock signals cannot be sent to field equipment, which brings potential safety risks for generator‑transformer set.
‑ Back‑plane connector: Connect to system back‑plane bus for data exchange with CPU and other boards.
‑ Front‑panel field connector: Connect to external relay coils, trip circuits and alarm devices.
‑ 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)
- 216AB61 module (HESG324013R101)
Complementary parts: REG216 system rack back‑plane, CPU processing unit, external relay loads, field shielded cables.
‑ Power off the whole rack before inserting or removing the module. Use shielded cables for field wiring to reduce electromagnetic interference.
‑ For spare‑part replacement: Verify complete part number HESG324013R101. After replacement, confirm back‑plane bus identification, verify each channel output action and self‑diagnosis fault reporting function.
‑ Module hardware fault will result in loss of binary output, which may affect generator‑transformer protection and interlock logic.
Generator and main‑transformer protection cabinets in power plants; ABB REG216 protection system; industrial spare‑part replacement.
- Dedicated binary relay output plug‑in for REG216 generator protection system, multiple galvanically‑isolated dry‑contact outputs for trip, interlock and alarm.
- Complete hardware self‑diagnosis function, real‑time detection of module internal faults.
- Status and fault information uploaded to upper‑level system through back‑plane bus for centralized monitoring.
- Standard Eurocard rack‑mount structure, easy installation and maintenance.
