Connecting the electronic insert FEI55 (8/16 mA)

The two-wire DC connection should, wherever possible, be connected as follows:
• To programmable logic controllers (PLCs),
• To AI modules 4-20 mA in accordance with EN 61131–2
The level limit signal is sent via an output signal jump from 8 mA to 16 mA current.
Power supply
Supply voltage: 11 to 36 VDC
Power consumption: < 600 mW
Reverse polarity protection: yes
Separation voltage: 0.5 kV
Signal on alarm
Output signal on power failure or in the event of device failure: < 3.6 mA
Connectable load
• U = connection DC voltage 11 V...36 V
• I = 16 mA
max
Connect the FEI55 (8/16 mA) as follows:
1. Make the connection as shown in the graphic.
2. Turn the cable gland until tight.
3. Set the function switch (5) to position 1
(operation).
!
Note!
Do not switch on the supply voltage until you have
familiarized yourself with the device functions as
described in chapter 5, "Operation". This will ensure
that you do not accidentally trigger any processes by
switching on the supply voltage.
4. Switch on the supply voltage.
