EPTA-S1

EPTA-S1 is an EPTA series snap-track mount transducer with fail-safe convert an analogue 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. It offers adjustable span and offset as well as manual override. This unit has no air consumption and is immune to mounting orientation. Also included is an analogue 0 to 5VDC feedback signal indicating the resultant branch line pressure. The standard maintain branch pressure on power loss while the fail-safe will drop the branch pressure to 0 psi on power loss. Application includes pneumatic dampers and valve actuators.
