The C-5230 Pneumatic Signal
Limiter is designed to impose Fig. 1: C-5230 Pneumatic
high and/or low limits on any Signal Limiter
pneumatic signal. The limits
imposed depend on the model
used. The limiter is available in
two models; the C-5230-2 is
designed to impose high or low Specifications
limits and the C-5230-3 is
designed to impose high and low
limits.
The low volume output
(45 SCIM) of the C-5230 is
isolated from the input and
repeats the input signal at a
1:1 ratio, limited by the high
and/or low adjustments.
Operation
The C-5230 contains an internal
pressure dropping orifice along
with one or two regulators
(depending on the model) for
adjusting the high and/or low
pressure limits. The high limit
regulator can be adjusted from
3 PSIG (21 kPa) to within 1 PSI
(7 kPa) of the supply pressure,
and the low limit regulator can be
adjusted from 2 PSIG
(14 kPa) to within 1 PSI (7 kPa)
of the supply pressure. The high
and low limits can operate within
0.25 PSI (1.7 kPa) of each other.
The output of the C-5230 equals
the low limit setting when the
input signal is below the low limit.
The output equals the high limit

Note: To remove the
regulator, move it from side to
side 1/8 in. while pulling on
the knurled brass knob; do
not pull directly upward.
Before the regulator can be
reinstalled in the high limit
location, the 3/32 in.
polyurethane plug must be
removed. The plug should be
stored in one of the holes as
shown in Fig. 2. Simply push it
into the hole with a small probe
such as a paper clip, being
careful not to puncture the plug.
Note: The pressure regulator
is properly installed when the
action tab is positioned
toward its respective HI or LO
marking. The regulator
should be pushed in firmly.
Mounting
The C-5230 is designed for
surface mounting using the two

with the instrument. Air

converting 5/32 in. connections
to 1/4 in. connections are
included with the unit.
If the output “O” connection of
the C-5230 is being fed by a
restricted supply (for example
T-9000 manifold), the supply “S”
connection must be closed off
with the furnished 1/16 in. yellow
cap.
Repair Information
Field repairs must not be made.
