Universal current connection with relay output (electronic
insert FEL64)
• Switches the loads via 2 potential-free change-over contacts
• 2 galvanically isolated change-over contacts (DPDT), both change-over contacts switch
simultaneously
• Functional testing without level change. A functional test can be performed on the
device using the test button on the electronic insert or using the test magnet (can be
ordered as an option) with the housing closed.

WARNING
An error at the electronic insert can cause the permitted temperature for touch-safe
surfaces to be exceeded. This presents a risk of burns.

Do not touch the electronics in the event of an error!
Supply voltage
U = 19 to 253 V
AC
, 50 Hz/60 Hz / 19 to 55 V
DC
Comply with the following according to IEC/EN61010-1: provide a suitable circuit
breaker for the device and limit the current to 500 mA, e.g. by installing a 0.5 A fuse
(slow-blow) in the power supply circuit.
Power consumption
S < 25 VA, P < 1.3 W
Connectable load
Loads switched via 2 potential-free changeover contacts (DPDT)
• I
AC
≤ 6 A (Ex de 4 A), U~ ≤ AC 253 V; P~ ≤ 1

• I
DC
≤ 6 A (Ex de 4 A) to DC 30 V, I DC ≤ 0.2 A to 125 V
According to IEC 61010, the following applies: Total voltage from relay outputs and power
supply ≤ 300 V.
Use electronic insert FEL62 DC PNP for small DC load currents, e.g. for connection to a
PLC.
Relay contact material: silver/nickel AgNi 90/10
When connecting a device with high inductance, provide a spark suppressor to protect the
relay contact. A fine-wire fuse (depending on the connected load) protects the relay
contact in the event of a short-circuit.
Both relay contacts switch simultaneously.
Behavior of output signal
• OK status: relay energized
• Demand mode: relay de-energized
• Alarm: relay de-energized
Terminals
Terminals for cable cross-section up to 2.5 mm
2
(14 AWG). Use ferrules for the wires.
Overvoltage protection
