Key Functional Features

Continuous Constant-Current Monitoring

• Constant Current Source: Injects a stable 1.5 mA monitoring current into the supervised circuit
• Full Fault Detection: Identifies circuit interruptions, poor connections, high contact resistance, and wire breaks
• Contact Welding Detection: Recognizes welded contacts in circuit-breaker auxiliary switchesABB Group
• Voltage Loss Detection: Triggers alarm for complete loss of auxiliary voltage in the monitored circuit
• Supply Voltage Supervision: Monitors its own auxiliary power and signals failure if supply is lost
• Non-Intrusive Operation: Monitoring current does not affect or activate the trip circuit under normal conditions

Optical Isolation & Noise Immunity

• Galvanic Isolation: Complete optical separation between monitoring and relay circuits
• Ground Loop Elimination: Isolation prevents interference from differing ground potentials
• High Noise Rejection: Multi-stage filtering suppresses electromagnetic interference (EMI/RFI)
• Transient Protection: 6 kV surge immunity on all terminals (IEC 61000-4-5)
• Polarity Insensitivity: Operates correctly regardless of DC input polarity

Preset Time Delay Function

• Fixed 3-Second Delay: Prevents false alarms during normal circuit-breaker operationABB Group
• Anti-Flicker Filtering: Ignores transient voltage dips and momentary contact disturbances
• Debounce Functionality: Filters contact bounce and temporary signal fluctuations
• Secure Tripping: Ensures only sustained faults activate alarm outputs
• Selective Fault Recognition: Differentiates between temporary disturbances and permanent faults

Dual Indication System

• Front-Panel LED Indicators:
  • Green LED (OK): Illuminates steady for normal, fault-free operation
  • Red LED (FAULT): Lit continuously when a fault is detected
• Output Relay Signaling:
  • Normally energized during healthy operation
  • De-energizes (drops out) on fault detection or supply loss
  • Provides both normally open (NO) and normally closed (NC) alarm contacts
• Local & Remote Status: Simultaneous local visual indication and remote signaling capabilityABB Group
