4.6 Connecting the electronic insert FEI54 (AC/DC with

relay output)

The universal voltage connection with relay output (DPDT) operates in two different voltage
ranges (AC and DC).
Note!
When connecting devices with a high inductance, use a spark suppression system to protect
the relay contacts.
Power supply
Supply voltage: 19 to 253 V AC, 50/60 Hz or 19 to 55 V DC
Power consumption: max. 1.6 W
Reverse polarity protection: yes
Separation voltage: 3.7 kV
overvoltage category II
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; U~ max. 253 V; P~ max. 1500 VA at cos  = 1;
P~ max. 750 VA at cos  > 0.7
• I– max. 6 A to 30 V; I– max. 0.2 A to 125 V
• The following applies when connecting a functional low-voltage circuit with double
isolation as per IEC 1010: Sum of voltages of relay output and power supply max. 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 to position 1
(operation).
!
Note!
Do not switch on the supply voltage until you
have familiarized yourself with the device
functions as described on Seite 38 "Operation".
This will ensure that you do not accidentally
trigger any processes by switching on the supply
voltage.
4. Switch on the supply voltage.
