4.10 Connecting the electronic insert FEI55 (8/16 mA;
SIL2/SIL3)
The two-wire DC connection should, if possible, be connected as follows:
• To programmable logic controllers (PLCs),
• to AI modules 4 to 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.
Power supply
Supply voltage: 11 to 36 V DC
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 to 36 V DC (non-hazardous area and Ex ia)
– 14.4 to 30 V DC (Ex d)
•I
max
= 16 mA
Functional safety (SIL)
The electronic insert FEI55 meets the requirements of SIL2/SIL3 in accordance with IEC 61508/
IEC 61511-1 and can be used in safety systems with corresponding requirements.
An exact description of the requirements in terms of functional safety can be found in document
SD278F/00.
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 to position 1
(operation).
!
Note!
Do not switch on the supply voltage until you have
familiarized yourself with the device functions as
described on Page 49 "Operation". This will ensure
that you do not accidentally trigger any processes
by switching on the supply voltage.
4. Switch on the supply voltage.
