ACREL Digital Temperature and Humidity Controller

From $231.00Sale Price
ACREL Digital Temperature and Humidity Controller is a panel-mounted temperature and humidity controller for monitoring and controlling environmental conditions inside electrical equipment. It measures temperature from -40.0 °C to 99.9 °C and humidity from 0%RH to 99%RH, with relay control for heating, temperature reduction and humidity management. RS485 Modbus RTU communication and analogue transmitting output options support integration with suitable monitoring and control systems.
 
Options:
C: RS485 (Modbus-RTU)
J: Alarm
M: Two Analog Output (programmable 4-20mA)
Quantity

The ACREL Digital Temperature and Humidity Controller combines temperature and humidity measurement with control functions in a panel-mounted instrument. It is designed for electrical equipment where excessive temperature, low temperature, humidity or condensation can affect operating conditions.

Acrel specifies the controller for high-voltage switchgear, terminal boxes, ring network panels and box-type transformer substations. The measured temperature range is -40.0 °C to 99.9 °C, while humidity can be measured from 0%RH to 99%RH.

How it works

  • The controller measures temperature and relative humidity within the monitored equipment.
  • Temperature control can be configured for heating over -40.0 °C to 40.0 °C or temperature reduction over 0.0 °C to 99.9 °C.
  • Humidity control is specified over 20%RH to 90%RH.
  • Relay contacts provide control outputs with a rated contact capacity of 5A at AC250V.
  • An optional transmitting output is specified as DC 4-20mA or DC 0-20mA.
  • RS485 communication with Modbus RTU allows connection to compatible monitoring or control systems.

Why choose this product?

  • Combines temperature and humidity monitoring with control functions in one panel-mounted device.
  • Provides a broad temperature measurement range suitable for electrical equipment environments.
  • Supports RS485 Modbus RTU for connection to compatible control and monitoring systems.
  • Wide AC/DC 85-265 V auxiliary power supply simplifies power-source selection.
  • Suitable for applications where controlling temperature and humidity helps reduce the risk associated with condensation and unsuitable environmental conditions.

Benefits

The ACREL Digital Temperature and Humidity Controller provides local monitoring and automatic environmental control rather than relying solely on separate temperature and humidity instruments. Its communication and analogue output options can also make measured conditions available to a wider control or monitoring system where required.
