OPTOCOUPLER SERIES FOR HIGH GALVANIC ISOLATION UP TO 22 KVDC
STANDEX ELECTRONICS' OPTOCOUPLERS ARE DESIGNED FOR HIGH GALVANIC ISOLATION OF UP
TO 22 KVDC
Standex Electronics' optocoupler series is designed specifically for the
galvanic separation of input-to-output power circuits, providing both electrical
and physical isolation meeting ATEX and IECEx requirements. This high-voltage
isolation pairs with a very high insulation resistance up to 1013 Ω and operates
in less than 10 µsec and creepage distances from input to output in the range
from 12.7 mm to 35 mm.
Optocouplers essentially operate in all kinds of extremely hazardous, explosive,
moist, or dirty environments, as well as in reliable medical equipment over a
temperature range of -40°C to +85°C. They draw no potentially hazardous arc by
transferring their digital or analog signal information from input to output.
Engineered with no moving parts, optocouplers operate safely for billions of
operations without interference from magnetic fields. If the internal LED is
used with <50% of the nominal current, then the lifetime of the optocoupler can
increase by a factor of 10. Furthermore, they can operate or transfer
information at a 50 kHz rate. Compared with relays, optocouplers experience only
negligible output delay times.
Typical applications include any potentially hazardous locations or explosive
atmospheres where combustion or ignition is a safety concern, such as any
spark-resistant tools, portable electrical and lighting products, or other
battery-operated devices used in electric and electronic circuitry. Mining
operations, chemical processing plants, and some medical processing plants are
just a few examples.
Features
* Galvanic separation between input and output circuits
* Analog and digital signal transfer is possible
* Marginal coupling capacities between input and output
* Minor output delay times compared to relays
* Long life due to non-abrasive mechanical wear
* I/O isolation resistance up to 1013 Ω
* Operation is unaltered by a magnetic field
* The photodiode can cycle in µs with up to 500 kHz
* Isolation voltage between input and output up to 22 kVDC
* Able to invert the output signal during transfer
* ATEX- and IECEx-certified
* The lifetime factor is increased by 10x if the LED is used with <50% of the
nominal current
Applications
* Production facilities with flammable gas, liquid, or dust
* Medical equipment
* Hazardous or non-arcing environments
* Non-sparking or spark-resistant tools
* Mining, oil, and gas exploration and production
