The electro-pneumatic converter installed in site converts a 4

to 20mA DC operation signals from an electronic controller

into proportional 19.6 to 98.1 kPa {0.2 to 1.0kgf /cm

matic signals for transmitting to pneumatic positioner, or op-

erating pneumatic final control elements such as diaphragm

valves, etc.

FEATURES

1. High conversion accuracy

2. Various types

3. A low input resistance of 200 permits two converters to
