Brand: Jiangsu Acrel Micro-grid Research & Development Institute

Acrel WHD46-33 Digital Temperature And Humidity Controller

Acrel's Digital Temperature and Humidity Controller, WHD46-33, offers a measuring range of -40.0℃~99.9℃ for temperature and 0%RH~99%RH for humidity with a precision of ±1℃ for temperature and ±5%RH for humidity. It also provides DC 4-20mA or DC 0~20mA transmitting output, and a communication port of RS485, MODBUS(RTU) treaty. This controller features a durable output contact capacity of 5A/AC250V and an average work time without stoppage of ≥50000 houts. Working conditions include a temperature of -20℃~+60℃, humidity of ≤95%RH, and altitude of ≤2500m. Upgrade to the Digital WiFi Humidity Controller for remote control capability.
