Detailed Product Description

MODEL WISEDESCRIPTION:

DTI-902	Temperature Indicator in 96 x 96 x 75 mm
DTC-903	One or Two set point On-Off Controller 96 x 96 x 75 mm

PRODUCT DESCRIPTION:

Libratherm offers high quality and low cost microcontroller based Temperature Indicators and on-off controllers series 900. It accepts input from J, K type thermocouple or RTD (Pt-100). User can select one of the 3 different types of input using front panel keyboard. This is the added advantage over the fixed type of input.Being microcontroller based 1oC or 0.1oC indicating accuracy is achieved by software linearization. Two independent set points are programmable over the full range of the selected input. Each set point can also be configured for High Alarm (Internal relay energizes when actual temperature value exceeds the set point), Low Alarm (Internal relay energizes when actual temperature value is below the set point) and OFF state. Outputs are in the optically isolated in the form of DC pulse, AC SSR (Triac) or electromechanical relays. SMPS power supply is utilized to operate this indicator controller in the wide range of AC supply of 90 to 250VAC.
