ABB 216AB61 HESG324013R100 / HESG216881 Binary Output Module

Full English name: ABB REG216 216AB61 Binary Output Module/Digital Output Unit

Material number/version: HESG324013R100 (hardware), HESG216881 (software/firmware)

2、 Core description (official positioning)

216AB61 is a dedicated 16 channel relay type digital output expansion module for ABB REG216 generator/transformer protection system. It is used to convert logical 

instructions such as tripping and alarm of the protection device into passive dry contact signals, directly driving external relays, circuit breakers, indicator lights and other 

actuators to achieve fault isolation and status indication.

3、 Key functions and features

Channel specification: 16 independent relay dry contact output (passive)

Contact capacity: 5A @ 250V AC/30V DC (resistive); 2A @ 250V AC (inductive)

Power supply mode: 24V DC is provided by the REG216 host backplane, without the need for external power supply

Isolation design: Optoelectronic isolation between channels, with strong industrial anti-interference capabilit

Status indication: Each channel is equipped with LED indicator lights (on=output closed) for on-site diagnosis

System integration: Directly plug into the REG216 host backplane and communicate through the Modulus Bus bus

Configuration method: Use REG216 software to configure the output logic and mapping relationship

Environmental adaptation: Operating temperature range of -40 ° C to+70 ° C, industrial grade EMC design

Diagnostic function: supports hardware self-test, channel status feedback, and fault recording
