Opto-couplers are normally given with an
output voltage supply from 5…48 VDC.
These values should not be cut or exceed-
ed on any occasion.
The load current should not be higher than
the stated max. output current.
Continuously exceeding this value will
destroy the output stage.
The derating curve shows the dependency
of the output current as a function of the
Ambient temperature (see under the
respective product on the following
pages).
2-pole AC output
A special semiconductor element (TRIAC)
in the output stage of the opto-coupler is
used to switch AC voltages.
As for the DC-versions the appropriate
parameters (such as voltage, frequency,
max. load current, ambient temperature)
should be given consideration.
A neutral voltage switch ensures that the
load is switched only in the voltage zero.
To protect against voltage spikes, the
modules are allways fitted with appropriate
protection elements (varistors, RC-combi-
nation).
Opto-coupler
Sample circuit
3-pole DC output
This type of output stage requires for safe
function a potential-linked output voltage
supply with an output that is either positive
switching (common reference potential is
GND or 0 V) or negative switching
(common reference potential is the positive
voltage pole).
Standards
Weidmüller opto-coupler comply with the
following standards:
EN 50 178
Furnishing of power engineering systems
with electronic equipment
DIN VDE 0106 Part 101
Protection against flow of dangerous
currents into the human body; basic
requirements for reliable separation within
electrical equipment.
DIN VDE 0884
Optoelectronic coupling devices for reliable
separation
DIN VDE 0109
Insulation coordination within low-voltage
system including clearance and creepage
distances for equipment
Protective circuit
All opto-coupler have a protective circuit in
the output (generally a free-wheeling
diode).
To prevent decoupling of interference
signals to other leads the load side
should be protected.
