Power Supply

Digital 3 1/2 digit

4~20mA DC (Input resistance 250W) Full-scale value may vary in the case of airflow measurement.

2-wire type direct current power supply for use with pressure transmitter: 24V DC non-internal, or

4~20mA DC (load resistance less than 500W)

In the case of airflow measurement, input signal is the extracted square root of the output signal.

Within ± 1%F.S. (at 20°C) For airflow measurement: 15-100%F.S extracted output value only.

100V AC ± 10% 50/60 Hz  EMP2 about 7VA, EMP3 about 6VA
