The Isocom Components 2004 LTD TLP521-4XGB Optoisolators-Transistor, Photovoltaic Output offer superior electrical isolation with an operational voltage of 5.3kV. Featuring a dual-in-line 16 pin dip form-factor, this product offers four-channel transistor, photovoltaic output. Such a design allows each channel to be independently controlled and can withstand a high level of electrical noise within its output channel. The TLP521-4XGB has a low input current of 100 uA which ensures efficient power consumption while its output current of 25mA ensures that even high power consuming circuits can be controlled with zero power loss. The TLP521-4XGB is ideal for applications that require high voltage and high current control with superior electrical isolation such as motor controllers, HVAC systems, automated processes, and instrumentation control.
