Original ABB 216AB61 Binary Output Unit Spare

The Original ABB 216AB61 Binary Output Unit Spare is the binary output unit of the ABB REG 216 numerical generator protection system, confirmed by ABB’s official REG 216 operating instructions. Per the manual, 216AB61 is the Binary Output (O/P) unit of the REG 216 hardware family — alongside 216EA61 (analogue input) and 216DB61 (binary input & tripping unit). It transmits signals generated by the protection functions to external units, enabling remote signaling, alarm annunciation and output actions. With sixteen solid-state output channels, it drives field devices under 24 V DC with short-circuit protection.

Original ABB 216AB61 Binary Output Unit Spare is the output stage of the REG 216 generator protection system: it takes the binary commands produced by the protection logic and drives external equipment — trip paths, alarms, annunciators and remote signals. Its sixteen short-circuit-protected solid-state channels and LED status indication make it a practical, high-density output interface for the REG 216 hardware set, where it works beside the 216EA61 input and 216DB61 tripping units.
