Contribution to Miniaturization

Another solution would be Panasonic’s capacitive coupled isolation technology. PhotoMOS devices feature a capacitive coupled driving circuit, a patented technology unique to Panasonic. Unlikely optically coupled LED-driven devices, the Capacitive Coupled technology is equipped in the smallest package size (TSON), with external dimensions of only 1.8 x 1.95 x 0.8mm. Additionally, this PhotoMOS device features a low input current of 0.09mA (typical) for power savings and a higher ambient temperature rating of up to 105 degrees Celsius. With its ultra-small package size, this product contributes to overall system miniaturization.

Longer Life with High Current

Lastly, when considering longer life with high current capabilities, Panasonic offers a Power type PhotoMOS Relay which is an excellent replacement for traditional mechanical relays. PhotoMOS devices can be used in the Analog to Digital input module to provide insulation for each channel. These devices offer current capabilities up to 6A and unlimited switching life to provide a maintenance-free and highly reliable functioning system with faster switching capability for speedy operation. PhotoMOS can also be used to replace transistors on the PLC's output control module, which eliminates a common failure mode due to the miswiring of the transistor.
