TELECOMMUNICATION PROGRAMMABLE CONTROLLERS DC-OUTPUT MODULE

The TOSHIBA TLP627A, -2, and -4 consist of a gallium arsenide infrared emitting diode optically  coupled to a darlington connected phototransistor which has a 350V high voltage of collector-emitter breakdown voltage.
The TLP627A-2 offer two isolated channels in a eight lead plastic DIP package, while the TLP627A-4 provide four isolated channels per package.

Collector-Emitter Voltage   : 350V(MIN)
Current Transfer Ratio       : 1500% (MIN)
Isolation Voltage             : 5000Vrms(MIN)
