The Comet PA8652 is a versatile, low-cost sensor for digital probes and binary inputs, featuring PoE support
€250.00
The Comet PA8652 is the versatile low-cost Ethernet sensor for up to 4 digital temperature or humidity probes and 3 binary inputs. With PoE, 12V output for detectors and web interface – perfect for comprehensive environmental monitoring
The Comet PA8652 is the most versatile model in the PAx6xx series. It allows the connection of up to four digital temperature or combined temperature-humidity probes as well as three binary inputs for detecting states (e.g., door contact, flood detector or other two-state signals).
A special highlight is the option to power connected detectors directly with 12 V from the device – even during PoE operation. This eliminates the need for additional power supplies and significantly simplifies installation.
The binary inputs are flexibly configurable for voltage signals, dry contacts or two-wire flood detectors. The PA8652 is the ideal solution for comprehensive environmental monitoring, where binary states such as flooding, door opening or device status must be recorded in addition to temperature and humidity.

- Connection of up to 4 digital probes
- 3 binary inputs for status monitoring
