PAC-77T
temperature meter 72 x 72 mm with contacts
The PAC-77T 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.
Features
- temperature meter with 2 displays
