Control side of the opto-coupler
interface
3 basic circuits are to be differentiated on
the input side of the opto-coupler#s inter-
face:
- as a pure DC input with polarity protec-
106
Opto-coupler
tion diode wich prevents the opto-cou-
pler from being destroyed if the input
polarity is reversed.
- as an AC/DC input:
Wrong polarity of the DC input signal is
not possible with this switching.
The disadvantage of an AC/DC input cir-
cuit (driven by DC signal) is the low
switching rate since the charging capacitor
(CL, necessary for AC-input signal) lowers
the max. switching rate.
- pure AC-Input:
* Sample circuit
Here, too, the charging capacity lowers
the max. switching rate considerably.
Weidmüller opto-coupler with AC/DC
or AC input signals are designed for
40…60 Hz power supply.
With AC-signal input the max. switching
rate is below half the power supply
frequency.
A high switching rate is not possible, oth-
erwise continuous switching in tune with
the power frequency would occur.
Output side of the opto-coupler
Weidmüller opto-coupler are designed and
sized for a wide variety of applications.
Demands regarding the load side of opto-
couple modules could be:
- power amplification
- signal conditioning
- short-circuit protection
- interference proof, etc.
To fulfil these requirements, the opto-cou-
pler must contain additional electronic
components which determine the func-
tionality of the opto-coupler.
Thus there are 2 basic output variations
for opto-coupler
Output as
- 2 pole and
- 3 pole circuits
2-pole DC output
The 2-pole DC output is comparable to a
conventional switch. With this type it is
immaterial where the load is in the output
circuit. It is, however, important to provide
the necessary output supply voltage with
the right polarity.
