ABB 216NG62A HESG441634R1K Binary Output Module

‑ Power Supply: Powered by REG216 rack back‑plane bus (5 VDC, 24 VDC)

‑ Power Consumption: ≤ 8 W

‑ Mechanical Structure: 6U Eurocard rack‑mount plug‑in board, metal front panel, back‑plane parallel bus connector

‑ On‑board Resources: Multi‑channel relay drive circuit, galvanic isolation circuit, channel status LED logic, self‑diagnosis unit, B448C parallel back‑plane bus interface

‑ Communication Interface: Internal B448C parallel back‑plane bus, no external communication port

‑ Galvanic Isolation: Field output channels are electrically isolated from system internal logic bus

‑ Interfaces: Front‑panel field wiring connector, back‑plane system bus connector, per‑channel status LED array

‑ Status LED Indicators: Power, Run, Module Fault, per‑channel output status LEDs

‑ Weight: Approx 0.43 kg

‑ Multiple isolated relay dry‑contact outputs for protection trip, equipment interlock, logic blocking and alarm signal output.

‑ Receives protection logic commands from system CPU through B448C parallel back‑plane bus and performs on‑off output actions.

‑ Uploads relay contact status and module self‑diagnosis fault information to main processor for upper‑level HMI monitoring and event logging.

‑ Comprehensive hardware self‑diagnosis function, detects power‑supply abnormality, drive circuit failure and internal hardware faults, and reports fault status to CPU.

‑ All configuration parameters are set via 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 supply, relay drive circuits and internal hardware status. Detected faults activate fault LED and send fault word to system CPU.

‑ Front‑panel LEDs show real‑time status of each output channel. No local numerical display; all status and fault codes are read from upper‑level HMI workstation.

‑ Module hardware failure will cause loss of corresponding binary output channels. Protection trip and interlock signals cannot be transmitted to field equipment, bringing potential safety risks for generator‑transformer set.

‑ Back‑plane connector: Connect to REG216 B448C parallel back‑plane bus for data exchange with CPU and other plug‑in modules.

‑ Front‑panel field connector: Connect to external trip relays, trip coils and alarm auxiliary 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)

‑ Power off the whole rack before inserting or removing the module. Field wiring shall adopt shielded cables with single‑end shield grounding to reduce electromagnetic interference.

‑ For spare‑part replacement: Verify complete part number HESG441634R1K. After replacement, confirm back‑plane bus identification, verify each channel output action and self‑diagnosis fault‑reporting function.

‑ Module hardware fault results in loss of binary output channels, which may affect generator‑transformer protection and interlock logic.
