APE-2S-3C

APE Series - Ethernet-Based Measurement Units without Display

The APE-2S-3C is a compact Ethernet-based monitoring unit without display, supporting two digital temperature or temperature/relative humidity (T/RH) sensors and three additional digital contact inputs for external alarm devices. It is ideally suited for monitoring telecommunications rooms, server rooms, technical installations, and other mission-critical environments where both climate conditions and status or alarm contacts need to be monitored.

The APE series represents a cost-effective generation of Ethernet-based monitoring units designed for reliable temperature and relative humidity monitoring. The series is intended for applications where good measurement accuracy is required without the need for high-end sensor technology. With support for protocols such as Modbus TCP, SNMP (v1/v2c/v3), HTTP(S), HTTP GET (JSON/XML), and IPv4/IPv6, the monitoring units can be easily integrated into building management systems (BMS), SCADA environments, and cloud platforms such as OnlineSensor.

The compact APE monitoring units are available in 1-channel, 2-channel, and 4-channel versions and support cost-effective digital sensors for temperature and temperature/relative humidity measurements. Multiple measurement values are available for each connected sensor. For example, a 4-channel model can accommodate four T/RH sensors, providing up to eight measurement parameters. The 2-channel version additionally features three digital contact inputs for connecting external alarm devices or dry contacts.

Powered via Power over Ethernet (PoE) or 5–24 VDC, and equipped with integrated memory, extensive network functionality, and modern security features, the APE series offers an efficient and cost-effective solution for applications in commercial buildings, technical rooms, storage facilities, schools, offices, and general industrial environments.
