EP-8000 Series
Electro-Pneumatic Transducer
Description Applications
The EP-8000 Electro-Pneumatic Transducer • typically used with pneumatic valve or
converts a 0 to 10 VDC or 4 to 20 mA signal damper actuators
from an electric controller into a proportional • sequencing can be provided through a
pneumatic output pressure signal. Four Johnson Controls® V-9502 Valve Actuator
models are available, which are grouped into Positioner or D-9502 Damper Actuator
two basic versions: low-volume output units Positioner
(non-relay) and high-volume output units
(relay). Repair Information
If the EP-8000 Series Electro-Pneumatic
Features Transducer fails to operate within its
