ACREL Temperature and Humidity Module
ACREL Temperature and Humidity Module is designed to monitor temperature and relative humidity inside electrical equipment and enclosed switchgear. It is intended for applications such as medium and high voltage switch cabinets, terminal boxes, ring main units and box substations. The sensor provides RS485 communication using Modbus RTU and operates from a DC 12-24V auxiliary supply, with DIN rail mounting for straightforward installation.
The ACREL Temperature and Humidity Module provides continuous measurement of temperature and humidity in electrical equipment and enclosed switchgear environments.
Acrel specifies the WH-M for monitoring the internal conditions of medium and high voltage switch cabinets, terminal boxes, ring main units and box substations. Its housing is designed to provide ventilation around the sensing module while allowing practical installation and wiring.
The sensor uses RS485 communication with the Modbus RTU protocol, allowing measured data to be accessed by a compatible master device such as a PC or PLC. The manufacturer specifies a 1-second collection frequency and a DC 12-24V auxiliary power supply.
How it works
- The ACREL Temperature and Humidity Module measures the temperature and relative humidity surrounding the sensor.
- Measurements are collected at a specified 1-second collection frequency.
- Data is communicated through RS485 using Modbus RTU.
- A compatible Modbus master, such as a PC or PLC, can query the sensor for measurement data.
- The sensor is designed for 35 mm DIN rail installation, making it suitable for electrical control and distribution equipment.
