COMET SP008 – 230 V Voltage Presence Sensor

COMET SP008 – 230 V Voltage Presence Detector 

The COMET SP008 is a reliable voltage presence detector for 230 V AC networks – the ideal solution for monitoring power supply availability in controllers of the Hxxxx and HxxxxR series. It instantly detects whether voltage is present and provides a clear digital signal (6 V when voltage present, 0 V when power is absent) to binary inputs – perfect for power failure reporting, alarm systems, building automation, or process monitoring.

The sensor simply plugs into a Type C socket and delivers a stable output signal via its 1.8 m cable. The green LED lights up when voltage is present, providing instant visual feedback. With a response time of about 1 second and a minimum load of 500 Ω, it is fast and dependable. Its compact design and durable build make it an ideal accessory for continuous operation.

The SP008 is especially useful when combined with COMET controllers – it provides early detection of power failures and enables automatic responses such as alarm activation or switchover to backup power. No complicated installation required – just plug in and connect.
