Product Description
TTD1N Wall Mount Digital Temperature Transmitter/ Controller
TTD1N Wall Mount Digital Temperature Transmitter with optional LCD&keys as below:
Applications & Features
- TTD1N are designed for indoor environment temperature measurement and control
- High performance digital temperature sensor and digital technology applied, ensure accurate measurement, fast response & 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
- Light and state of art housing, easy installation
- Wide working temperature range
- All electrical terminals are on the inside bottom, avoid any possible destroy to PCB when wiring
- LCD & function keys can set parameters and calibrate output, so that the product becomes a stand alone controller
