ACREL Temperature & Humidity Controller with RS485
ACREL Temperature & Humidity Controller with RS485 is a compact temperature and humidity controller for monitoring environmental conditions inside electrical equipment enclosures. It measures temperature from -40.0 °C to 99.9 °C and humidity from 0%RH to 99%RH, with configurable control functions for heating, ventilation and humidity management. Depending on the configuration, it supports analogue transmission and RS485 Modbus RTU communication, making it suitable for switchgear, terminal boxes, ring network panels and transformer substations.
The ACREL Temperature & Humidity Controller with RS485 provides continuous monitoring and control of temperature and humidity in electrical equipment environments.
The controller uses a temperature and humidity sensor to monitor conditions and can operate connected heating and ventilation equipment. This allows the enclosure environment to be managed when conditions move outside the configured control points.
The ACREL Temperature & Humidity Controller with RS485 is particularly suited to electrical distribution equipment where excessive humidity, condensation or unsuitable temperature conditions may affect equipment operation. Acrel lists high-voltage switchgear, terminal boxes, ring network panels and box-type transformer substations among its intended applications.
How it works
- The connected sensor measures the temperature and relative humidity of the monitored environment.
- Temperature can be monitored across a range of -40.0 °C to 99.9 °C, while humidity is measured from 0%RH to 99%RH.
- Configurable temperature control parameters can be used for heating and ventilation functions.
- Humidity control can be set within the specified 20%RH to 90%RH control range.
- Relay outputs can switch connected external equipment such as heaters or fans.
- Where the applicable configuration includes communication, RS485 Modbus RTU can be used for connection to a monitoring or control system.
