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

The receiver controllers are used with remote pneumatic transmitters to provide proportional control in pneumatic control systems. They are designed primarily for use with pneumatic transmitters; however, they maybe used with any pneumatic device having an output of 3 to 15 psig, such as thermostats or humidistats. Both direct and reverse acting models are available and each device is of the dual input type, with remote setpoint capability. These devices may be used as single input devices by using only the desired input.

• Nozzle and flapper relay-type receiver-controller; linear, stable and responsive. Three inputs for primary, reset and remote control point adjustment (may be used with one or two inputs).
• Slide-type throttling range and authority adjustments
