Does the max current flow of scxi-1163R channel only 200mA?

[hau]

I want to use scxi-1163R and scxi-1326 to control the ASCO solenoid valves(water control).
The input voltage/current of valve is 24VDC/500mA.
But the max current of scxi-1163R is just 200mA. Does it mean that i can not directly connecting the valve to module?
Is there any other solutions?

Hi Hau,

I am assuming that you have an external power supply connected to the valves and that you want to use the SCXI-1163R to open/close the circuit. As you stated, the SCXI-1163R has a max current rating of 200mA. Unfortunately, going above the max current rating could damage the relay. However, National Instruments does offer SCXI switches that are capable of handling the current and voltage ratings that you have specified. See the following link (page 4 of the PDF document) for a list of the switches that National Instruments offers.

Have a great day!
