Pneumodular Diverting Relay (3 to 20 psig)

Description

The 2353-501 and 502 Diverting Relays are snap-acting
devices with adjustable set points. They are 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
signal for a final control device.
The 2353-503 is a non-adjustable, 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. Its primary function is
the comparison of two input signals from outside and inside
enthalpy transmitters, providing SPDT pneumatic
two-position switching based on the transmitted enthalpy
values, however, it may be used with any two pneumatic
input signals up to a maximum of 30 psig.
