PRELIMINARY - Low-Cost Sensor for Two Digital Probes and Three Binary Inputs, Ethernet Output and PoE
The PA8652 is the most versatile model in the PAx6xx series. It allows for the connection of up to four digital temperature probes or combined temperature and humidity probes and also offers three binary inputs for status detection or connection of external detectors.
A unique feature of the device is the ability to power connected detectors with 12 V directly from the terminals even when powered via PoE, which eliminates the need for additional power supplies and significantly simplifies installation.
The device inputs can be configured for voltage signals, dry contacts, or for connecting a two-wire flood sensor.
The PA8652 is ideal for comprehensive environmental monitoring where, in addition to temperature or humidity, it is necessary to monitor flooding, door opening, or other binary states.
Main Benefits:
- Support for external digital temperature and humidity probes + monitoring of 3 binary states
- Allows probe connection up to 40 meters in length
- Ability to power external detectors from the device
- Power supply 15–24 V or PoE (IEEE 802.3af)
- Integrated backup memory
- Modern web interface, IPv4/IPv6 support, Modbus TCP, COMET Cloud, and fully encrypted communication (HTTPS, SNMPv3, TLS)
- Integrated detachable bracket for easy installation
