Analog Output-Pneumatic (AO-P) Module

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.
