EP-8000 Series Electro-Pneumatic Transducers

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.

Features and Benefits

♦ Compact, Simple Design Eases installation on a variety of mounting
surfaces, including direct mounting on pneumatic
valve actuators

♦ Choice of 0-10 VDC or
4-20 mA Input Range
Interfaces with a wide range of controllers, making
the unit ideal for retrofit installations

♦ Hypodermic Needle Test
Allows for fast and easy output pressure signal

♦ Factory Set, Fully
Adjustable Zero and Span
Facilitates field calibration, saving installation costs

♦ High Accuracy with Low
Provides many years of use with less time spent on


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



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.


Parts Included

· EP-8000 Transducer

· No. 8 3/8 in. sheet metal screws (2)

Tools Needed

· flat-blade screwdrivers, 3/32 in. and 1/4 in.

· 5/32 in. drill bit and drill


Regardless of the mounting method chosen, the
EP-8000 must be mounted within 5° of vertical for
proper operation. 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
an EP-8000 directly to a damper actuator.

To mount an EP-8000 on a pneumatic valve actuator,
the EP-8000-101 Mounting Kit (ordered separately)
must be used. The EP-8000, in conjunction with the
EP-8000-101, can be mounted on the following
actuators: 4R, 5R, 8R, V-400, V-500, or V-3000-1
Series Valve Actuator with or without a V-9502 Valve
Actuator Positioner. It can also be
used with a V-3000-8001 Series Valve Actuator with or
without a V-9502.

Panel Mounting

Mount the EP-8000 on a flat, vibration-free surface,
using the following steps:

1. Mark two mounting slots on the mounting surface
using the integral mounting bracket as a template.

2. Drill a pilot hole at each of the marked locations.

3. Secure the EP-8000 in place using the two No. 8
screws provided.
