ABB 216DB61 HESG324063R0100 Binary Input & Trip‑Output Unit

‑ 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, 8‑channel bipolar trip output driver, output amplifier supervision circuit, channel status LED logic, back‑plane parallel bus interface

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

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

‑ Interfaces: Front‑panel field wiring connector, back‑plane system bus connector, channel status 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 of the 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 continuously monitors trip output drive circuits for fault detection.

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

‑ 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.

‑ 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 display for numerical values; 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, which creates 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)

1、216DB61 module (HESG324063R0100)

‑ 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 HESG324063R0100. 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 input‑output channels, which may affect generator‑transformer protection and interlock logic.
