SPER1B1C4 ABB Trip Circuit Supervision Relay

Description

ABB SPER1B1C4 Full Introduction & Technical Specifications
Product Overview
Brand: ABB
Model: SPER1B1C4
Official full product name: Trip Circuit Supervision Relay

Basic Physical Information
Overall external dimension: 40 mm width × 70 mm height × 110 mm depth
Net weight: 0.14 kg
Production origin: Finland, ABB European electrical relay professional manufacturing base
Customized international customs HS code: 8536490000, applicable to power system monitoring electromagnetic relay for industrial control circuits
Installation mode: standard 11-pin pluggable structure, supporting 35mm DIN rail installation and flat surface screw fixed installation with matched terminal base; front panel protection grade IP20, only suitable for closed indoor cabinet environment, not applicable for outdoor open installation.
Input Technical Parameters
Monitored circuit input voltage range: 40 V ~ 265 V AC/DC wide universal voltage input;
Static monitoring current for detection loop: rated constant monitoring current 1.5 mA, low current design avoids extra power consumption to monitored control circuit;
Auxiliary power supply input: 40 V ~ 265 V AC/DC adaptive power supply, consistent with monitored circuit voltage range, no extra independent power wiring required;
Passive signal collection input: built-in high-impedance sampling circuit, continuously collect loop resistance change and voltage fluctuation inside monitored trip circuit without external signal access channels.

Output Technical Parameters
Fault alarm relay output: single group isolated mechanical relay contact output, contact rated load AC250V/5A, DC220V/1A, used for remote alarm signal transmission and external interlock trigger;
Status indication output: front panel dual LED indication, yellow OK light for normal circuit state, red FAULT light for fault abnormal state;
Delay anti-disturbance output logic: built-in fixed short delay action mechanism, automatically shield transient signal fluctuation during circuit breaker opening and closing action to avoid false alarm output;
No analog signal and digital communication bus output, only relay switch quantity and LED local indication as output forms.
Core Product Characteristics & Performance Features
Comprehensive loop fault detection capability
The relay can accurately detect circuit open circuit, excessive contact resistance, contact welding, control voltage loss and internal power supply failure of the relay itself, realizing full-cycle self-supervision of trip loop working state.
Anti-false alarm optimization design
Preset fixed operating delay suppresses instantaneous voltage fluctuation and transient interference during circuit breaker switching, greatly reducing false alarm probability under equipment dynamic operation conditions.
