(3) each x (4) types for unlimited applications.
Diverse DIP-6,8 assortment includes:
(3) HCPL-2531 - Dual TTL, hp/Agilent
(3) MC3009 - Triac, 250 Volt, Motorola
(3) MC3012 - Triac, Sensitive, Motorola
Low 5 mA Trigger Input, UL Rated
(3) LT1547AT1 - Solid-State Relay, Siemens
400 V, 5.3 KVrms Isolation, UL Rated
Optically coupled devices allow you electrically insolate input and output circuits to withstand thousands of volts by using light as the control medium. A LED input circuit is electrically insulated from the optical detector. Optical isolation also pays a big bonus by eliminating ground loops and noise propagation.
This assortment gives you flexibility. You have a choice of Bi-Polar NPN, FET or TRIAC outputs. Even if you do not require the extreme electrical insulation, they make a quick, simple and vibration-proof substitute for mechanical relays.
