ALSCHU 480
Art. no. 602921
Alarm protection device, plug-in for 230 V~ (with groun-
ding contact adapter plug), with or without alarm transmit-
ter and relay switching output (changeover contact)
ALSCHU 480 P
Art. no. 602923
as above, but with volt-free switching output and looped
socket
General:
The ALSCHU 480(P) is a versatile alarm and protection
device. Its universal
input (3.5 mm jack bush) allows a lot
of different external sensors to be connected.
That includes sensors with a switching threshold <100
kOhm like water sensors, oat switches, level switches,
magnetic contacts, safety shut-off mat etc. In case of
an alarm the internal buzzer sounds and a connected
device (i.e. pump, machine) is switched on or off via the
grounding contact adaptor plug (ALSCHU 480). The
desired switching function can be set via selector switch
I / II. ALSCHU 480 P switches on/off external devices via
a potential-free 2-pole switching output. The
grounding
contact
socket of ALSCHU 480 P is always current-car-
rying.
Specications:
Power supply: 220/240 V 50/60 Hz
Power consumption: approx. 1 VA
Sensor input: 2.5 mm jack bush
Switching threshold: input resistance <100 kOhm
(e.g. NPN no active, relay, reed
contact, etc.)
Switching output:
480: via isolated ground receptacle
480 P: potential-free normally open/
closed contact via 2-pole cable,
brought out 0.5 m
Switching function:
I: switching output current-carrying
in alarm condition
II: switching output currentless in
alarm condition
Switching power:
480, 480 P: 250 VAC, 10 A (ohmic load),
max. 2400 VA
480 P: 120 VDC, 2 A (ohmic load),
max. 240 W
Protection device for universal application
