2506/2516 Receiver/Controller
June 2017
12
All pressure connections on 2506/2516 receiver/controllers are 1/4 NPT internal fittings (figures 3 and 9). Use 1/4‐inch
piping or 3/8‐inch tubing to these connections.
If remote venting is required, see the Vents subsection below.
Supply Connection
WARNING
Severe personal injury or property damage may occur if the instrument air supply is not clean, dry and oil free or
non‐corrosive gas. While use and regular maintenance of a filter that remove particles larger than 40 micrometers in
diameter will suffice in most applications, check with an Emerson Automation Solutions field office and industry
instrument air quality standards for use with corrosive gas or if you are unsure about the proper amount or method of air
filtration or filter maintenance.
If the existing supply is corrosive, make sure the tubing and instrument components that contact the corrosive medium are
of suitable corrosion‐resistant materials, or change to a noncorrosive supply medium.
WARNING
Personal injury or property damage may occur from bursting parts due to overpressuring any system component. To avoid
injury or damage, provide pressure‐relieving or pressure‐limiting devices if supply or input pressure could exceed the
maximum allowable pressures listed in table 3.
It is recommended that supply pressure pass through a filter/regulator combination such as a Fisher 67CFR. See table 3
for recommended supply pressures to the receiver/controller.
Typical supply pressure for the 67CFR is clean dry air or a gas at a pressure of 2.5 bar (35 psig) to a maximum of 17 bar
(250 psig). For specific regulator limits, see the appropriate regulator instruction manual.
Output Connections
See figure 3.
Use 3/8‐inch tubing between the actuator and the receiver/controller. Connect the output (diaphragm) connection to
the appropriate actuator connection.
Instrument Connection
See figure 3.
Use 3/8‐inch tubing to connect the output from the control device to the INSTRUMENT connection on the
receiver/controller.

WARNING
If a flammable or hazardous gas is used as supply pressure medium, personal injury or property damage could result from
fire or explosion caused by the accumulated gas. Injury or property damage could also result from contact with flammable
