PN-VPC

ELECTRONIC/PNEUMATIC-TRANSDUCER

PRODUCT DATA

APPLICATION

An E/P Transducer accepts a proportional voltage signal
from an electronic controller and converts it into a pro-
portional pneumatic signal of 0.2 to 1.0 bar to operate
pneumatic actuators or reset pneumatic controllers.
The PN-VPC accepts a 2...10 Vdc / 4...20 mA signal. It
includes a voltage to current converter. The PN-VPC
requires an external 24 Vac power supply.

MAINTENANCE

A full range of maintenance programs is available from your
local registered Trend office.
