4.8 Connecting the electronic insert FEI54 (AC/DC with
relay output)
The unversal voltage connection with relay output (DPDT) operates in two different voltage ranges
(AC and DC).
Note!
When connecting devices with high inductivity, use a spark suppression system to protect the relay
contacts.
Power supply
Alternating voltage 19 V...253 V, 50/60 Hz or DC voltage: 19 V...55 V
Power consumption: max. 1.5 W
Reverse polarity protection: yes
Separation voltage: 3.7 kV
FEI54 overvoltage protection: overvoltage category III
Signal on alarm
Output signal on power failure or in the event of device failure: relay de-energized
Connectable load
• Loads switched via 2 floating changeover contacts (DPDT)
• I~ max. 6 A (EEx d 4 A), U~ max. 253 V; P~ max. 1500 VA at cos ϕ = 1, P~ max. 750 VA at
cos ϕ > 0.7
• I– max. 6 A (EEx d 4 A) to 30 V, I– max. 0.2 A to 125 V
• When connecting a functional extra low voltage circuit with dual insulation in accordance with
IEC 1010, the following applies: the sum of the voltages of the relay output and power supply
must not exceed 300 V.
Connect the FEI54 (AC/DC relay) 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.
