The Apollo 55000-750USA is a short-circuit isolator for the XP95A addressable loop, wall-mounted in a white housing and wired directly into the signaling line circuit at set intervals. If a wire-to-wire short occurs on the loop, the isolator automatically disconnects only the affected section between itself and the next isolator, then restores power and data to that section the instant the short is cleared, keeping the rest of the loop's devices in service.
Key Features
- Automatic short-circuit isolation and self-restoration for XP95A loops
- Confines a fault to the segment between adjacent isolators, minimizing device loss
- Wall-mounted, low-profile white enclosure
Technical Specifications
- Power: 24VDC, 2.5 mA
- Loop placement: up to 20 devices permitted between isolators
- Compatibility: Apollo XP95A addressable loop systems
Certifications
