The ETR121 and ETR141 controllers offer three- or four-digit displaysand double programmable set-point. This allows selection of thermocouples type J, K, S, R, thermoresistances PT100, PTC 1000?, NI100, NTC 10K (typically used in the refrigeration industry) and PT1000 (widely used in air-conditioning). These controllers are configurable for signals of 0-1V, 0-10V, 0-20mA, 4-20mA. The ETR141is suitable for applications on ceramics or metalworking kilns/furnaces with temperatures over 1000°C or for reading of inverters with upper limit of 9999. Potentiometers 6K and 150K enable the reading of linear transducers. Two set-points are available and two outputs configurable by parameter as relay or SSR control. A single-relay version is also available with RS485 serial communication. The converter accuracy and sampling frequency make these units suitable for applications requiring an economical cost/features ratio.
