FEM24 electronic insert (AC/DC with relay output)

Alternating voltage AC: 19...253 V, 50/60 Hz or DC voltage 19...55 V
Power consumption max. 1.3 W
Reverse polarity protection
Separation voltage: 2.2 kV
FEM24 overvoltage protection: overvoltage category II
Universal current connection with relay output
Power supply:
Please note the different voltage ranges
for AC and DC.
Output:
When connecting a device with
high inductance, provide a spark arrester
to protect the relay contact.
A fine-wire fuse (depending on the
load connected) protects the relay
contact in the event of a short-circuit.
Both relay contacts switch simultaneously.
DPDT (double pole double throw)
* When jumpered, the
relay output works with NPN logic.
** See below "Connectable load"
Note!
Please note the different voltage ranges for direct and
alternating current.
