RSA-TTD2A,3,4,5,6A Digital Temperature

Applications & Features

• These transmitters/controllers can be used for temperature monitoring & controlling in duct (RSA-TTD2A), water and steam pipe(RSA-TTD4A) or outside air(RSA-TTD3A) and remote(RSA-TTD5A), strap-on(RSA-TTD6A) models
• High performance digital temperature sensor and digital technology applied, ensure accurate measurement fast response and good long term stability
• Multiple outputs selection, over voltage and reverse polarity protection, high reliability and anti-interference capability
• Optional relay for alarm or ON/OFF control
• Wide working temperature range and fast response
• LCD & function keys can set parameters and calibrate output, so the product can become a stand alone controller
• High protection rate up to IP65
