TLP523, TLP523-2, TLP523-4
Programmable Controllers DC-Output Module Solid State Relay
Unit: mm
The TOSHIBA TLP523, -2 and -4 consist of an infrared emitting diode coupled with a silicon, Darlington connected, phototransistor which has an integral base-emitter resistor to optimize switching speed and elevated temperature characteristics.
The TLP523-2 offers two isolated channels in an eight lead plastic DIP package, while the TLP523-4 provides four isolated channels per package.
