The Analog Output-Pneumatic (AO-P) Module is an electric-to-pneumatic interface between
the Fume Hood Controller and the pneumatic actuator. The AO-P Module translates electrical
signals from the Fume Hood Controller into pneumatic signals that command the actuator.
The AO-P Module consists of two industrial grade solenoids that supply or bleed air to the
actuator by using a pulse modulation technique. See Figure 9. Minimum air supply to the AO-
P Module is 18 psi and the maximum is 30 psi. The valves are rated for 24 Vac.
