The Pneumatic Modular Control System (MCS) is designed to ease the assembly and installation of a pneumatic control system in several ways. The modularity of design and assembly speeds the prebuilding of panels and simplifies field hookup through the use of easily identified connections. The modular format allows the use of simplified engineering drawing symbols developed specifically for modular controls so that panels may be built as drawn directly from the submittal drawings. In addition, final system start-up and calibration checks are made easier because the panels match the drawings they were built from, thereby saving field labor time.

• Most compact panel-mounted pneumatic control system. Several control devices perform dual functions. No control device need be made up of separate parts.
• All modular control devices mount on MCS-S socket, which snaplocks to MCS-BP backplate (available in several sizes)
• Sockets form pneumatic piping field above control devices, and provide places for slip-in electrical connectors below them, physically separating pneumatic tubing and wiring
• Control devices may be removed from socket and replaced without disturbing tubing, wiring, or other control devices
• Pneumodular controllers, relays and switches may be mounted as stand-alone devices using available mounting brackets

Snap-acting devices with adjustable setpoints designed for a variety of switching and interlocking functions in pneumatic control systems where the application requires one or more of the following functions: feeding and exhausting branch lines, diverting a supply line to either one of two branch lines, or diverting one of two supply lines to one branch line. The primary function of these devices is to convert a proportional pneumatic signal, at a predetermined setting, into a positive pneumatic switching action.
R2353503 is a nonadjustable, snap-acting, signal-comparing diverting relay designed for use in pneumatic control systems where the application requires a pneumatic switching function based on the comparison of two proportional pneumatic input signals.

• Positive two-position snap-action, SPDT pneumatic switching
