ABB 216DB61 HESG324063R100 H Binary‑Input & Trip‑Output Unit (Hardware Revision H)

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

‑ Power Consumption: ≤ 9 W

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

‑ On‑board Resources: 16‑channel binary input conditioning circuit, 8‑channel bipolar trip output driver, trip amplifier supervision circuit, channel LED logic, back‑plane parallel bus interface

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

‑ Galvanic Isolation: Field input and trip‑output channels are electrically isolated from system internal bus

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

‑ Status LED Indicators: Power, Run, Module Fault, per‑channel Input / Trip‑Output status LEDs

‑ Weight: Approx 0.44 kg

‑ 16‑channel binary digital inputs for collecting field contact signals: breaker position, auxiliary contacts, interlock and blocking conditions. Two inputs can be configured for external trip‑enable / trip‑block functions.

‑ 8‑channel bipolar trip outputs to drive external trip relays, breaker trip coils and interlock loads.

‑ Built‑in amplifier supervision monitors trip output drive circuits for fault detection.

‑ Receives protection trip and interlock commands from system CPU over back‑plane bus and executes output actions.

‑ Uploads binary input status, trip‑output state and module self‑diagnosis fault information to main processor for upper‑level HMI monitoring and event logging.

‑ Complete hardware self‑diagnosis for power‑supply abnormality, bus interface error and output‑driver failure.

‑ 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 216AB61 module. Hardware revision H is mechanical‑pin‑compatible with earlier revisions (G / J), internal component upgrade for improved EMC performance.

‑ Continuously monitors input‑channel status, trip‑output driver health, module power and internal hardware faults. Detected faults activate fault LED and send fault word to system CPU.

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

‑ Module hardware failure will cause loss of related binary‑input acquisition and trip‑output channels. Protection‑trip commands and interlock signals cannot be transmitted to field equipment, creating safety risks for generator‑transformer set.

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

‑ Front‑panel field connector: Connect to field auxiliary contacts, trip‑relay coils and interlock 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 use shielded cables with single‑end shield grounding to reduce electromagnetic interference.

‑ For spare‑part replacement: Verify complete part number HESG324063R100/H. After replacement, confirm back‑plane bus identification, verify each binary‑input acquisition, trip‑output action and amplifier‑supervision fault‑reporting function.

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

Generator and main‑transformer protection cabinets in thermal / hydro power plants; ABB REG216 protection‑control system; industrial spare‑part replacement for older hardware revisions.
