Schneider Electric S510, S511 Series (2390 Series) TAC Pneumodular® Gradual Switches
The S510 gradual switch is designed to allow manual setting of a desired pressure, up to main air pressure, where the application requires remote positioning of final control devices or remote control point adjustment of a pressure signal is desired. The S511-5 and S-511-10 have been designed with an internal high pressure selector relay, primarily for use as a minimum position switch for damper operation when used with actuators having a 5 or 10 psig span, respectively. Various dial plates are available for each model with specific switch applications.
S510 and S511 Gradual and Minimum-Position Switches can easily be mounted any of three ways:
• Flush-mounted on panel face. Dial plate locks onto switch body and is held in place by tightening the mounting nut from the rear. Provides exposed adjustment.
• Mounted with two screws and MCS-G Gasket to MCS-S Socket. Provides concealed adjustment.
• Mounted remotely on the various mounting brackets listed K511, K512 and K514 “flush-mount” the gradual switches with or without flush-mounted 2 in. pressure gauges.
• TAC PNEUMODULAR: All ports clearly labeled. Ports align with MCS-S terminals.
