Product Overview

• Part No: 216DB61, full part code HESG324063R100/J / HESG216882/A
• Brand: ABB
• Origin: Switzerland
• Supporting System: REG216 generator comprehensive protection system, matched with 216AB61 output board to form complete signal loop
• Type: Binary digital input acquisition module

• FunctionCollect all field switch state signals for generator, transformer and high-voltage switchgear. Receive contact feedback signals including circuit breaker closing/tripping position, protection auxiliary contacts, grounding fault signal, door interlock and local/remote mode signals. Convert field dry contact/DC24V switching signals into bus digital signals and upload to REG216 main control unit for protection logic judgment, fault recording and remote SCADA uploading. Cooperates with 216AB61 output board to realize full closed-loop protection signal input and output.
