The ITC 450/470 meter is equipped with one current input (0-20mA), two voltage inputs (0-10V and 0-150
mV), one RTD input (Pt 100/500/1000) and one TC input (thermocouple: K, S, J, T, N, R, B, E). Temperature of
cold ends is compensated automatically. RTD and TC inputs are fully linearised. It is allowed to use only one
input at the same time. Input ranges are described in the next chapter. Result is showed on 4-digit LED
display.
The device can be equipped with two or four relay (or OC type) outputs. Optionally
ITC 450/470
with two
relays (or OC type) outputs can be equipped with active current output, passive isolated current output or
active voltage output. Device ITC 450/470 is equipped with RS-485 / Modbus RTU communication interface
and sensor supply output. The meter can be ordered in two power supply versions.
ITC 450/470 can be used for controlling and regulation of processes need proportional and threshold control
like: temperature processes (heating or cooling), valves controlling or other.
