4.6 Connecting the electronic insert FEI51 (AC 2-wire)
!
Note!
Connect in series with an external load.
Power supply
Supply voltage: 19 to 253 V AC
Power consumption: < 1.5 W
Residual current consumption: < 3.8 mA
Short-circuit protection
FEI51 overvoltage protection: overvoltage category II
Signal on alarm
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 (10 mA) or >
0.5 VA at 24 V AC (20 mA)
• Relays with a lower holding power or rated power can be operated by means of an RC module
connected in parallel.
• For relays with a maximum holding power or rated power < 89 VA at 253 V AC or < 8.4 VA at
24 V AC
• Voltage drop across FEI51 max. 12 V
• Residual current with blocked thyristor max. 3.8 mA
• Load switched directly into the power supply circuit via the thyristor.
Connect the FEI51 (AC 2-wire) as follows:
1. Make the connection as shown in the
graphic.
2. Tighten the cable gland.
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 Section 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.
