SRT-94 Process Indicator for temperature sensors

The SRT-94 process indicator is designed for use with PT100, PT500 and PT1000 temperature sensors and Type K, S, J, T, N, R, B, E thermocouples.  It has the option of 0, 2 or 4 relay outputs and the LED indication on an alarm event.  Signal re-transmission is option with the 2 relay function also.

Power Supply: 19V - 50V DC, 16V - 35V AC, 85 - 260V AC/DC

Input Types: PT100, PT500 and PT1000, Type K, S, J, T, N, R, B, E thermocouples

Output Types: 0, 2 or 4 relays

Signal Re-transmission: operating range max. 0 - 24 mA

Sensor Power Supply: 24V DC +5%, -10% / max. 100 mA

Accuracy: ± 0,25% ± one digit in the entire operation range

Case dimensions: 96 x 48 x 100 mm

Communications Interface: RS-485, ModBus RTU

The SRT-94 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. A 4-digits, 20-millimetre LED display enables seeing of measured values from a distance. The RS-485 enables data transmission in production process monitoring systems. 0, 2 or 4 relay (or OC) outputs make it possible to adjust the level of the measured signal. Every relay output can be controlled according to one or two threshold values.
