Process indicator SRT-77 series

temperaturedigitalLED

The SRT-77 temperature meter has one input: thermoresistance (Pt100/500/1000) or thermocouple (K, S, J, T, N, R, B, E). Measurement is linearised by the polynomial characteristics. The device with thermocouple input has additional measurement range (-10...90 mV) mainly for diagnostics of measurement circuits. The main advantage of regulator are two rows of display. The first one presents measuring value, second one - programmed values: max and min. 1 or 2 relay (or OC) outputs make it possible to control heating / cooling processes. The RS-485 enables data transmission in production process monitoring systems. The REL / OC control outputs can adjust the level of measured signal and are controlled according to one or two threshold values. The meter can be configured with the local keyboard or free S-Config software via the RS-485 communication port. Input range - Pt100, Pt500, Pt1000: -100...+600°C TC K: -200...+1370°C, S: -50...+1768°C, J: -210...+1200°C, T: -200...+400°C, N: -200...+1300°C, R: -50...+1768°C, B: +250...+1820°C, E: -200...+1000°C -10...90mV Output type - Open Collector: I=30 mA, U=30V DC, P=100 mW relay I=1A, U=30V DC/250V AC (cosø=1) Power supply - 16...35V AC, 19...50V DC 85..260V AC/DC 11,4...15V AC/DC
