Specifications
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.
Features:
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.
