BEAMEX MC5P - MC5 P Current Measurement

37
Current Measurement
The current measurement terminals are located in the E module.
Required settings Options/description
Quantity Current
Funct/Port E: I(meas)
External supply
When the measuring circuit includes an
external power supply, use the terminals
shown in the picture below.
Internal Supply
When you want to use MC5P’s 24 V termi-
nal to supply the measuring circuit, use the
terminals shown in the picture below.
Based on the terminals in use, MC5P automatically acts as either a
pure current measuring unit or as a current measuring unit while at
the same time supplying the measuring circuit.
Notes.
Check the polarity of your connections. The arrows in the previous
pictures describe the correct flow of current.
If you are using a transmitter with HART capability, make also a
connection to MC5P’s HART terminal. For more information con-
cerning HART connections, see Appendix 1, chapter Connecting
MC5P and a HART Instrument on page 138. Information concern-
ing current measurement parallel to a test diode can be found in
part C, chapter Current Measurement Parallel to a Test Diode,
Connections on page 99.
