The IC3600AFRA1A1A combines analog signal processing with rugged durability, making it essential for maintaining operational continuity in aging infrastructure across power generation, oil and gas, and heavy manufacturing .
Designed for 120–240V AC/DC power systems, the IC3600AFRA1A1A features 25 metal male terminal prongs for seamless integration with other Speedtronic modules, enabling multi-channel fault monitoring. Its compact form factor (15.9 cm high × 17.8 cm wide) and DIN rail mountability simplify installation in space-constrained control panels. Diagnostic test points (TP1–TP4) provide real-time monitoring of ground fault currents, while 32 jumper switches allow configurable sensitivity thresholds (0.1–10A) and trip delays (0.1–5s). Key components include two LM339J low-power quad comparators, four transistors, four red LED indicators (CR1–CR4), and polyester vinyl capacitors for noise filtering. The board’s vertical component mounting optimizes heat dissipation, critical for sustained operation in extreme temperatures (-50°C to +50°C) .
Compliant with industry standards like IEC 60255-11, the IC3600AFRA1A1A ensures compatibility with legacy Mark I/II systems while supporting retrofitting to hybrid analog-digital control environments. By detecting ground faults and isolating faulty circuits, it mitigates risks of electrical fires and equipment failure, extending asset lifespan and reducing maintenance costs. Its single-channel design makes it ideal for applications requiring focused fault detection without redundancy .
