The Honeywell FC-TELD-0001 is a specialized Earth Leakage Detector (ELD) designed for Safety Manager and Fail Safe Control (FSC) systems. It continuously monitors the insulation resistance of 24V DC field power supply circuits relative to ground, detecting both gradual degradation and sudden faults.
By identifying leakage conditions early, the module ensures stable system operation and reliable execution of Safety Instrumented Functions (SIF). We supply this unit in 100% Brand New original condition for maximum safety and reliability.

Proactive Hazard Prevention
Detects low-level (“soft”) ground faults caused by insulation wear or moisture before they escalate into critical failures, enabling planned maintenance instead of emergency shutdowns.
Redundant System Integrity
Identifies the first ground fault in floating 24V DC systems, eliminating hidden risks that could lead to dangerous dual-fault conditions.
Simplified Troubleshooting
Provides clear diagnostic feedback to the controller, allowing rapid identification of affected power segments and reducing maintenance time.
Galvanic Isolation Safety
High isolation design ensures monitoring does not introduce electrical noise or interfere with safety logic, preserving SIL-rated system performance.
How does the FC-TELD-0001 notify the operator of a fault?
It communicates directly with the Safety Manager controller, generating alarms and diagnostic messages on the HMI when leakage exceeds configured thresholds.
Can this module monitor multiple power supplies simultaneously?
Typically, one module monitors a single power group. Multiple units are used for systems with several isolated DC power zones.
What is the recommended maintenance interval?
Although it operates continuously, leakage thresholds should be verified during annual safety proof testing.
Is it possible to adjust the sensitivity of the leakage detection?
Yes. Adjustable thresholds allow customization to avoid nuisance alarms while maintaining protection for critical circuits.
