EP-8000 Series Electro-Pneumatic Transducers
Product/Technical Bulletin
Code No. LIT-216370
Part No. 24-85368-36, Rev. H
Issued February 2016
EP-8000 Series Electro-Pneumatic Transducers
convert a voltage or current signal from an electronic
controller into a pneumatic output pressure signal. An
increase or decrease in the input signal proportionally
increases or decreases (respectively) the output
pressure signal from the EP-8000. Four models are
available, which are grouped into two basic versions:
low-volume output units (non-relay) and high-volume
output units (relay).
The EP-8000 is designed to output a proportional
pneumatic control signal in response to an electronic
control signal. All units feature barbed air connections
for 5/32 or 1/4 inch O.D. polytubing. Sequencing of
pneumatic valve or damper actuators can be
accomplished using a Johnson Controls® V-9502
(Valve) or D-9502 (Damper) Actuator Positioner.

Operation Input Versus Output Relationship
A change in the electrical input signal modulates the
amount of air that exhausts from the leakport,
producing an output pressure directly proportional to
the input signal. Input and output pressure and flow
relationships are detailed in Figures 3 through 5.
A potentiometer located next to the wiring terminal
block is provided for field span adjustment, and a screw
located on the side of the EP-8000 is provided for zero
adjustment. (See Figure 2 for adjustment locations.)
The low-volume models are 1-pipe instruments, which
require a 0.007 inch restrictor (R-3710 Series, ordered
separately) in the supply air line.

Parts Included
• EP-8000 Transducer
• No. 8 3/8 in. sheet metal screws (2)
Tools Required
• flat-blade screwdrivers, 3/32 in. and 1/4 in.
• 5/32 in. drill bit and drill
Mounting
Regardless of the mounting method chosen, the
EP-8000 must be mounted within 5° of vertical for
proper operation. (Refer to Figures 6 and 7.) In most
cases, the vertical position of the EP-8000 can be
obtained by correctly positioning the transducer's
mounting bracket and/or angle bracket. Do not mount
