MPU 4.00 G - Schuhmann Messtechnik

Universal Temperature Converter
MPU 4.00 G
FEATURES
Input, switchable:
PT 100, 2-, 3-, 4-conductor switch
Range: -50…800 °C
Output, simultaneous:
Current 0(4)...20 mA and
Voltage 0(2)...10 V
Fine-adjustment of
offset and gain by trimmer
Galvanic 3-way isolation
of 4 kV
FUNCTION
The MPU 4.00 G is processing PT 100 signals and is
used for the precise measurement of temperature
with resistance thermometers in 2-, 3-, 4-wire
technique. They are switchable by slide switch.
It has a simultaneous output for current and
voltage.
The selection and respectively switchover of offset
and temperature range -50...800 °C can be done by
turn switch.
The fine adjustment of zero point and terminal
value is carried out by trimmer.
An adjustment of the device is not necessary
any longer.
Auxiliary power: 230 V AC/ 24 V DC
