The SRT-77 has dual display process meters with one input: thermoresistor (Pt100/500/1000) or thermocouple (K, S, J, T, N, R, B, E). The measurement is linearized with polynomial properties. The device with thermocouple input has an additional measuring range (-10…90 mV) mainly for diagnosis of measuring circuits. The main advantage of the regulator is two rows of screens. The first presents the measurement value, the second – programmed values: max and min. Control of heating/cooling processes is provided with 1 or 2 relay (or OC) outputs. RS-485 enables data transmission in production process monitoring systems. The REL / OC control outputs can adjust the level of the measured signal and are controlled according to one or two threshold values. The meter can be configured via the RS-485 communication port with the local keyboard or the free S-Config software.
