The 7I64 from Mesa Electronics, Richmond, CA, provides 24 isolated 48 VDC, 2.5 A output drivers. All output drivers are low saturation voltage MOSFETS for low power dissipation. Each of the 24 output switches is isolated from the others, allowing high-side, low-side, push-pull, and other output switch configurations. Features include 5–24 V input voltages; reverse protection diodes for use with AC inputs; a built-in watchdog timer; USB, RS-422, and SPI host interface methods; and compatibility with the company's Anything I/O cards.
