DESCRIPTION General telecom switching The LH1525 Relay are SPST normally open switches Battery powered switch applications (1 Form A) that can replace electromechanical relays in Industrial controls many applications. The Relay requires a minimal amount of Programmable controllers LED drive current to operate, making it ideal for battery powered and power consumption sensitive applications.

2 Instrumentation The Relay is constructed using a GaAIAs LED for actuation control and MOSFETs for the switching output. The Relay employs current-limiting circuitry and can be configured for AGENCY APPROVALS. AC/DC or DC-only operation. UL1577, file no. E52744. ORDERING INFORMATION. DIP-6 SMD-6. L H 1 5 2 5 # # # T R.
