ABB 216DB61 HESG 324063R100 | Binary input and Output Unit

The ABB 216DB61 HESG 324063R100 stands as a binary input and output unit, purpose – built for the critical task of reliable signal processing within RE.216 protection schemes. In the complex realm of power systems, this unit plays a pivotal role. It takes on the responsibility of precisely controlling and vigilantly monitoring tripping and signaling relays. Through such meticulous oversight, it safeguards the power systems, ensuring they operate both safely and with optimal efficiency.

Key Features:

• Model: 216DB61
• Product ID: HESG 324063R100
• Function: Binary input and output processing for RE.216 protection schemes
• Power Supply: 24V DC with redundant power supply
• Fuse Protection: F101 (2A fast, 5 x 20mm) to safeguard the power supply

Relay Configuration:

• 6 Tripping Relays:
  • Controlled by the 216DB61 tripping unit
  • Each circuit is connected to terminals with two series-connected contacts
• 14 Signal Relays:
  • Controlled by the 216AB61 binary O/P unit
  • N/O contacts and relays 1-4 with N/C contacts

Binary Signal Processing in RE.216 Scheme:

• Binary values:
  • Logic “0” (FALSE) and Logic “1” (TRUE)
  • Dual-indication signals: Two consecutive binary inputs are combined
  • Binary protection values: Used for tripping and status signaling

Configurable Signaling Output Modes:

1. Control signal relays and record events
   • Provides complete information on important signals
   • Pickup signal activates “General Start” (signal & event)
   • Tripping signal activates “General Trip” (signal & event)
2. Record events without controlling signal relays
   • No signal relays required, but signal status is recorded
   • Pickup signal activates “General Start” (event only)
   • Tripping signal activates “General Trip” (event only)
3. Neither control signal relays nor record events
   • No storage space used for unnecessary information
   • No effect on “General Start” or “General Trip”

System Integration:

• Auxiliary signal relays powered via 216AB61/216AC61 binary O/P unit
• Up to six 216AB61 and six 216AC61 units can be integrated into RE.216 systems

Device Status & Error Indicators:

Device Status Register (Hex Code Definitions):

• GNB (0002 Hex): Device not ready
• SSG (0010 Hex): General alarm for device failure
• FA0: Tripping channel driver failure
• FA1: Tripping relay module supply failure
• FA2: Data transmission error for a received tripping signal
• ZS: Timeout operation (Tripping signal not transmitted twice)
• BL1 & BL2: FA0 signal triggered blocking flip-flop for groups 1 & 2
• UP: I/P module supply failure
• DISB: ENABLE 1/2 and BLOCK 1/2 functions not active
