3-port base used for logic units
2-port base used for timers

All logic units require mounting on a separate 2 or 3 port base, available separately. Logic units have an input (green) and output (red) pressure indicator to show the state of the respective signal. Units are supplied with two captive screws for mounting on all types of base and sealing o-rings are in the bottom of each unit.

Logic Systems

Logic units are best thought of as miniature valves, whose purpose is to influence the behaviour of larger power valves. They achieve this by producing and receiving output and input signals, using the common air supply. In this way, they are able to monitor and control a whole sequence of operations with great accuracy and repeatability.
