Electrical Connection
5.2.2 Universal Current Connection with Relay Output
(Electronic Insert FEL44)
• Switches the loads via 2 volt-free changeover contacts
• 2 separate changeover contacts (DPDT)
Supply Voltage
U = 19 to 253 V AC, 50 Hz/60 Hz / 19 to 55 V DC
Power Consumption
S < 25 VA, P < 1.3 W
Connectable Load
Loads switched via 2 volt-free changeover contacts (DPDT)
• I
AC
≤ 6 A (Ex de 4 A), U~ ≤ 253 V AC; P~ ≤ 1500 VA, cos ϕ = 1, P~ ≤ 750 VA, cos ϕ > 0.7
• I
DC
≤ 6 A (Ex de 4 A) to 30 V DC, 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 FEL42 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
Overvoltage category II
Warning!
Risk of burns by hot surface
An fault at the electronic insert can cause the permitted temperature for touch-safe surfaces
to be exceeded.
Do not touch the electronics in the event of a fault!
Note
Observe the following as per IEC/EN 61010-1: 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 phase (not the neutral conductor) of the supply circuit.
