Why Choose 8- MOSFET?

Compared with relays, 8-MOSFET is more cheaper to drive four high-current loads (24 VDC at 10 A) and four high-voltage loads (240 VDC at 2 A). For applications that require fast, clean switching times, it will achieve the job more quickly and quieter. Also, it has nearly unlimited longevity with high endurance under heavy loads.

What’s more, it employs industrial-grade, pluggable connectors, which makes it easy to use. Thanks for its scalable feature, and only the I2C interface are occupied, so you’ll still have 24 GPIO pins to use for more complicated project. Moreover, headers are provided for the platforms of UNO, Nano, Teensy, Feather, and ESP32.

Two DIN-rail Mounting Options

Parallel to the Rail

The parallel mounting kit is ideal for a single card or a two-card stack. But it should be reminded that it may become mechanically unstable once you get two or three 8-MOSFET cards piled up on your Raspberry Pi.

Perpendicular to the Rail

By contrast, it is obvious that the perpendicular mounting kit can offer mechanical stability for any number of cards, for each card is secured to the DIN rail with a dedicated steel bracket. So, even with eight 8-MOSFET cards on your Raspberry Pi, you’ll still have room for other Raspberry Pi add-on cards.
