Product Overview
The EP2 electropneumatic pressure transducer uses micro-controlled poppet valve technology for highly accurate
pressure sensing. The poppet valves consume no air, eliminating unnecessary air losses in the system and allowing
for stable and reliable operation. The EP2 comes installed on standard SnapTrack, and an optional cover is available
to protect from dust and other environmental factors. An LCD display and LED indicators make it easy to read
system status at a glance.

EP2 Series Installation Guide
Dimensions
1. Mount the transducer using the screws provided. Avoid damaging the electronic components.
2. Wire the transducer and congure the jumpers for desired operation as shown in the Wiring and Conguration section below.
3. Attach pressure tubing to the hose barbs. Observe MAIN and BRANCH port labels. Use exible ¼” O.D. poly tubing for the main
and branch pneumatic connections. Main supply pressure must not exceed 45 psig.

Observe precautions for handling static sensitive
devices to avoid damage to the circuitry that
is not covered under the factory warranty.
Jumper Configuration
Input Current (4 to 20 mA) orVoltage (0 to 5V or 0 to 10V)
Voltage For voltage mode of operation, select 0 to 5V or 0 to 10 V
Pressure Range Select 0 to 20 psi or 3 to 15 psi scaling
Operation Mode Select AUTO for normal operation or MANUAL to adjust pressure using the pushbuttons
Options
Alarm Mode Relay The alarm contacts open if the EP2 cannot obtain 80% of commanded pressure within two (2) minutes
Manual Mode Alarm Contacts open when manual mode is selected (auto mode contacts are closed)
Vent On Power Fail The EP2 vents the branch line pressure on power failure
Terminal Block Connections
GND/Common Power supply ground and signal common.
Input Signal 4 to 20 mA, 0 to 10Vdc, or 0 to 5Vdc input from the control system.
Power 22 to 30 Vdc, 20 to 30Vac. From the control system or external power supply or transformer.
Pressure Loss Alarm
(optional)
Normally closed, solid-state contacts open if the main supply pressure fails or if the transducer is otherwise unable to
produce the correct branch pressure. Connect to the digital input of the control system for alarm status indication. If
commanded pressure does not reach 80% within 2 minutes, the alarm contacts open.
• 0 to 20 psi alarm contact does not change state when the commanded pressure is 4 psi or less
• 3 to 15 psi alarm contact does not change state when the commanded pressure is 5.4 psi or less
NOTE: In 24 Vac transformer applications, one side of the transformer secondary is connected to the signal common. Some control systems may require a
dedicated power supply transformer or isolation transformer.
