Endress+Hauser Cerabar M PMC51 - Connecting the Measuring Unit; Terminals; Cable Specification; Load for Current Output

Electrical connection Cerabar M PMC51, PMP51, PMP55
16 Endress+Hauser
5.2 Connecting the measuring unit
5.2.1 Supply voltage
IO-Link
• 11.5 to 30 V DC if only the analog output is used
• 18 to 30 V DC if IO-Link is used
5.2.2 Current consumption
IO-Link < 60 mA
5.3 Terminals
• Supply voltage: 0.5 to 2.5 mm
2
(20 to 14 AWG)
• External ground terminal: 0.5 to 4 mm
2
(20 to 12 AWG)
5.4 Cable specification
5.4.1 IO-Link
Endress+Hauser recommends using twisted, four-core cable.
5.5 Load for current output
In order to guarantee sufficient terminal voltage, a maximum load resistance R
L
(including
line resistance) must not be exceeded depending on the supply voltage U
B
of the supply unit.
