Signal on alarm
The output signal on power failure or in the event of damage to the sensor: < 3.8 mA
Connectable load
• For relays with a minimum holding power or rated power:
• > 2.5 VA at 253 V
AC
• > 0.5 VA at 24 V (20 mA)
AC
• Relays with a lower holding power or rated power can be operated using an RC module
connected in parallel.
• For relays with a maximum holding power or rated power:
• < 89 VA at 253 V
AC
• < 8.4 VA at 24 V
AC
• The voltage drop across FEI51: maximum 12 V
• Residual current with blocked thyristor: maximum 3.8 mA
• Load switched directly into the power supply circuit via the thyristor.
Do not switch on the supply voltage until you have learned about the device functions
as described in section "Operation options" →  36. This will ensure that you do not
accidentally trigger any processes by switching on the supply voltage.
Connecting the FEI51
L1 L1 phase cable
N Neutral cable
PE Grounding cable
R External load
1. Connect the FEI51 according to the schema.
2. Tighten the cable gland.
3. Set the function switch to position 1.
4. Switch on the supply voltage.

DC PNP electronic insert FEI52

The three-wire DC connection should, wherever possible, be connected as follows:
• to programmable logic controllers (PLCs)
• to DI modules in accordance with EN 61131-2
A positive signal is present at the switch output of the electronic system (PNP).
