By using it, you can avoid the huge risk of program loss and equipment downtime caused by using inferior cards.
The most distinctive feature of this card is that the words "6ES7953-8LF31-0AA0" laser-engraved on the front are extremely deep and cannot be scraped off with a fingernail. There are 8 gold-plated contacts on the back, and the measured contact resistance is less than 20mΩ. The plastic shell of the card is dark blue with anti-slip patterns on the edges.
