APPLICATIONS
• Ideal for AC signal detection and monitoring
AGENCY APPROVALS
• UL1577, file no. E52744, double protection
i179037-1
• cUL tested to CSA 22.2 bulletin 5A
DESCRIPTION
• CSA 93751
The IL250, IL251, IL252, ILD252 are bidirectional input
optically coupled isolators consisting of two gallium
arsenide infrared LEDs coupled to a silicon NPN
phototransistor per channel.
• BSI EN 60950, BSI EN 60065
• DIN EN 60747-5-5 (VDE 0884-5)
• CQC GB4943.1-2011 and GB8898-2011 (suitable for
installation altitude below 2000 m)
The IL250 has a minimum CTR of 50 %, the IL251 has a
minimum CTR of 20 %, and the IL252, ILD252 has a
minimum CTR of 100 %.
The IL250, IL251, IL252 are single channel optocouplers.
The ILD252 has two isolated channels in a single DIP
package.
