MAMAC - Electropneumatic Fail Safe
-
Accepts either 24 VAC or 24 VDC
-
Can handle up to four transducers
-
Features isolated pneumatic ports that prohibit pressure mixing
-
Interfaces with EP-311/313 electropneumatic transducers to provide fail safe bleed to zero pressure
The EP-350 interfaces with up to four separate EP-311/313
electropneumatic transducers to ensure fail safe bleed to zero
pressure. The EP-350 solenoid holds a transducer's bleed port closed
until power is lost and then opens the port, which allows the branch
ports of all connected transducers to exhaust pressure upon power
failure.
The EP-350 incorporates an aluminium block manifold that is fitted
with four ¼-inch brass hose barbs and a single power solenoid. By
connecting transducers’ branch lines to the EP-350’s four hose
barbs, pressure ports are kept isolated from one another to ensure
that no pressure mixing occurs across pneumatic ports.
To power the EP-350, apply either 24 VDC or 24 VAC to the EP-350’s
two-position terminal block. To provide a pneumatic connection, tee
a line of ¼-inch poly tubing from one of the EP-350’s four ¼-inch
hose barbs to the branch line output of an electropneumatic
transducer.
