NOTES

1- Measured with input diode leads shorted

together and output leads shorted together.

2- RMA Flux is recommended.Duration can

be extended to 10 sec. max. when flow

soldering.

Whilst the devices are capable of

operating continually at the noted

elevated temperatures users should

be aware of the possibility of a

reduction in CTR over long periods

at high temperatures & currents.

SCHEDULE OF LIMITATIONS

EC TYPE EXAMINATION CERTIFICATE No. BAS01ATEX1278U/5

SCHEDULE OF LIMITATIONS

28th September 2012

1 - The Opto Isolator must be mounted on a p.c.b. having a CTI of at least 175 such that creepage and clearance distances are not

impaired. i.e.:- on an uncoated printed circuit board that maintains at least 10mm in air.

2 - The Opto Isolator may be used to provide isolation between either:-

(i) A non-intrinsically safe circuit and an intrinsically safe circuit, (Non IS:IS), where the IS circuit voltage is not greater than

75 Volts peak or d.c..

OR

(ii) Two intrinsically safe circuits (IS:IS), where the sum of the two circuit voltages is not greater than 375 Volts peak or d.c..

3 - The Opto Isolator must be installed such that the connection pins are provided with a degree of protection of at least IP20 where

gasses and vapours may be present. If the Opto Isolator is to be installed where dusts represent a hazard, then it must be

provided with a degree of protection of at least IP54 and the overall apparatus must be appropriately certified for the requirements

for Dusts.

4 - The Opto Isolator must be installed with external power limiting components as specified in EN60079-11:2012, Clause 8.9.2.

CERTIFICATE No.:- IECEx BAS 06.0021U

SCHEDULE OF LIMITATIONS

Date of Issue:- 2012-10-02

1. When used in intrinsically safe apparatus it will be necessary to determine a surface

temperature classification for the opto-isolator:-

ISSUE No.: 4

2. The Opto Isolator must be mounted on a printed circuit board such that creepage and

clearance distances are not impaired.

3. The Opto Coupler must be installed such that the connection pins are provided with a degree of protection of IP20 where

gasses and vapours may be present. If the Opto Coupler is to be installed within apparatus where flammable dusts represent

the hazard then it must be provided with a degree of protection of IP54 and the apparatus must be appropriately certified for

dust hazards.

5 - The Opto Isolator must be installed with external power limiting components as specified in IEC60079-11:2011 Ed 6, Clause 8.9.2.
