Installation Instructions

FieldPort SWA50
10 Endress+Hauser
Voltage drop
• If internal HART communication resistor is deactivated
• 3.2 V in operation
• < 3.8 V at start-up
• If internal HART communication resistor is activated (270 Ohm)
• < 4.2 V at 3.6 mA loop current
• < 9.3 V at 22.5 mA loop current
To select the supply voltage, pay attention to the voltage drop via the FieldPort SWA50. The
remaining voltage must be high enough to enable the start-up and operation of the HART field
device.
Power consumption
Max. 0.2 W at 22 mA and with internal HART communication resistor (270 Ohm)
Terminals
2 x 2-pin screw terminals
Cable entry
• "Remote mounting" version: 2 cable glands
• "Direct mounting" version: 1 cable gland and 1 direct cable entry from field device
Cable glands supplied
• Ex t-version: no cable glands. Dummy plugs are supplied.
• Ordering information, feature "060", option "B": M20 x 1.5 plastic version
• Ordering information, feature "060", option "C": M20 x 1.5 EMC version
Cable specification
Use cables that are suitable for the anticipated minimum and maximum temperatures.
Observe grounding concept of the plant.
2 x 0.25 mm² to 2 x 1.5 mm²
You can use unshielded cable with or without ferrules and shielded cable with or without ferrules.
If you select the "direct mounting" version and the "4-wire HART field device with active current
output and PLC or transmitter" electrical connection version, you can use core cross-sections of
0.75 mm² at maximum. If larger core cross-sections are required, we recommend remote
mounting.
Installation
Mounting methods
• Remote mounting
• Direct mounting on HART field device via either M20 or NPT 1/2" connection adapter
For remote mounting, we recommend the optional mounting bracket. Alternatively, you can secure
the remote version using pipe clips.
