Global Caché GC-SP1 feszültségérzékelő

In a server room where a critical network switch must never go dark, the GC-SP1 sits quietly across its power terminals, watching for the moment voltage disappears. When the switch loses power, the sensor’s contact closes instantly, alerting your Global Caché controller to trigger an alarm, send a notification, or fire a macro. It’s a simple, reliable way to turn any 3–24V AC/DC source into a digital status signal.

Key specifications

• Detects voltage from 3V to 24V AC or DC
• Optically isolated output protects your controller
• Output via 3.5mm mono jack, 1.8 m cable
• Screw terminals for secure input wiring
• Red LED indicates detection status
• Powered by the host Global Caché controller
• Operating temperature: 0°C to 50°C
• Mounts with adhesive backing or screws
• ABS plastic enclosure, black

Why choose it

The GC-SP1 eliminates guesswork about whether a device is actually on. Unlike current clamps or inline meters, it reads voltage directly at the source, so you get a true power-state signal. Optical isolation means your expensive controller is safe from voltage spikes, and the long cable lets you place the sensor exactly where you need it. Setup takes minutes with no external power supply.

Ideal use cases

• Monitoring power status of AV receivers, amplifiers, or projectors
• Detecting when a PC or server shuts down unexpectedly
• Triggering automation when a device enters standby mode
• Integrating legacy equipment into a modern control system
• Creating a simple power-failure alarm for critical hardware

Good to know

The sensor works with any Global Caché iTach or GC-100 series controller that has a sensor input. It draws negligible current from the monitored circuit, so it won’t affect performance. For best results, connect the screw terminals to the device’s power supply output, not the mains. The red LED gives immediate visual confirmation of detection, making troubleshooting straightforward.
