Mesa 4I20

• PC/104 card with 24 open drain 350 mA outputs
• 45V switching capability
• Outputs isolated from logic ground
• Short circuit protection

The 4I20 is a stackable PC/104 card with 24 open drain 350 mA outputs for solenoids, valves, relays, motors, incandescent lamps and other medium power DC loads.
The 4I20 outputs are galvanically isolated from logic ground to avoid ground loops, as the total ground return current be as much as 8.4 amps. The isolation also allows the 4I20 to drive ground referred loads.
