TECHNICAL CONSIDERATIONS (NOT FOR FIELD REPRESENTATIVE'S USE):
Use - For use only in products where the acceptability of the combination isdetermined by UL LLC.
USR indicates this product was investigated under the UL Standard for Safetyfor Optical Isolators, UL 1577, Fifth Edition, revised July 6, 2023.
Conditions of Acceptability - Each device shall be reviewed with respect tothe following conditions of acceptability:
1.

The capability of the device to control a load has not been
investigated.

2.

These devices should be installed in a suitable end product enclosure.

3.

The maximum junction temperature shall not be exceeded.

4.

For single protection devices, the insulation to the case has not been
evaluated. For double protection devices, the insulation to the casehas been evaluated to the isolation voltage specified in the ratings
table.

5.

In addition to meeting single protection requirements, double
protection optical isolators have also been investigated for use in up
to 250 V, 50/60 Hz circuits in audio, video, and similar equipment inapplications in which breakdown of the optical isolator may result in arisk of fire, electrical shock, or injury to persons.

CONSTRUCTION DETAILS:
General - The product shall be constructed in accordance with the following
description. All dimensions are approximate, unless specified as “max” or“min”.
Markings – As specified in the Section General.
