The Series EPTA is an electric to pneumatic transducer that
converts an analog input signal to a linearly proportionate pneumatic
output by modulating its control valves to regulate branch line pressure
to the set point determined by the input signal. All models incorporate
two low voltage valves, an integral inbarb filter, a 0 to 30 psi analog
gauge, an anodized aluminum manifold, and brass barbed fittings. The
EPTA offers adjustable span and offset as well as manual override. This
unit has no air consumption and is immune to mounting orientation.
Output pressure ranges include field selectable 0 to 10, 0 to 15, and 0
to 20 psig. Also included is an analog 0 to 5 VDC feedback signal
indicating the resultant branch line pressure. Universal 24 VAC/24 VDC
supply voltage and field selectable 4 to 20 mA, 0 to 5 VDC, 0 to 10 VDC,
or 0 to 15 VDC inputs ensure single unit compatibility with most
systems. The standard models maintain branch pressure on power loss
while the Fail-Safe models will drop the branch pressure to 0 psi on
power loss. Mounting configurations include a metal bracket mount in the
EPTA-B models and a snap-track mount in the EPTA-S models. The A-400
accessory kit will allow the EPTA-S models to be mounted on a standard
DIN rail.
