USB -3314 current limit

[hroussell]

I would like to know if there is any why to control the current on the USB 3314.  I am using these to drive a heater on a optical device and need to limit the current.  I limit the voltage in the program but I think the heaters are changing.

Thanks

Hello @hroussell

Assuming you mean the USB-3114, 16 channel, 16 bit high-drive analog voltage output device,

Unfortunately there is no way for you (the user) to control the amount of current drawn on this device.

You would need to develop and add your own current limiting device/circuit externally.
