Upgrading
a Pressure Switch from Electromechanical to Solid-State
could not be easier.
In
fact, when replacing a United Electric J120 or H121
pressure switch that interfaces with a PLC or DCS, use
the same mounting footprint, same 2-wires and same
conduit location! Viola! How easy is that!
This
document
will guide you thru selecting a "One Series" replacement
for the J120 or H121.
