4-20 mA HART Loop Protocol & Channel-to-Channel Isolation
Designed for pneumatic actuation loops, the MP904A5047 interfaces with electropneumatic positioners converting 4-20 mA HART loop protocol control signals into proportional air pressure. The physical mechanical assembly provides complete galvanic and electrical channel-to-channel isolation from process instrumentation circuits. This ensures high-accuracy pneumatic position control up to the 140 kPa maximum operating pressure limit without introducing electrical ground loops into associated controller field buses.
Frequently Asked Questions
Q: What air supply tubing diameter is supported by the MP904A5047 pneumatic connection?
A: The motor features an integrated barb fitting designed for 6 mm (1/4 in) polyethylene tubing.
Q: What are the maximum operating and safe burst pressure ratings for this actuator?
A: The maximum operating pressure is 140 kPa, and the maximum safe air pressure limit is 210 kPa.
Field Installation Guidelines
- Air Line Connection: Push clean, dry 6 mm (1/4 in) polyethylene tubing firmly onto the integrated barb fitting until seated completely. Secure with a tubing clamp if necessary.
- Pressure Regulation: Install a upstream air filter regulator set to not exceed the maximum operating pressure of 140 kPa. Never exceed the absolute safe limit of 210 kPa.
- Mechanical Linkage Alignment: Ensure the actuator push rod is aligned precisely with the driven damper or valve linkage to prevent side-loading during the full 90 mm stroke.
- Leak Testing: Apply pneumatic pressure and inspect all supply line fittings with soapy water to verify zero bubble formation prior to system commissioning.
