PAC-457T

field housing 230 x 150 mm with contact

CE

The PAC-457T digital 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 meter
is equipped with 4 LED diodes, indicating
exceeding of particular thresholds (R1, R2, R3,
R4). Relay (or OC) output makes it possible to
control processes ON/OFF type. The device
features a 4-button keyboard for programming
basic settings, which for greater security is
located under the front cover. In order to make
setting changes without unsealing the casing,
remote control can be included by means of an
(as accessories) infrared remote control unit.
The keyboard on this remote control unit is the
same as the device's keyboard (this applies to
the type IP 67 casing).
