The Yocto-4-20mA-Tx is a USB 4-20mA signal generator. With this device, you can drive any other device featuring a 4-20mA input. This is an insulated device: the USB part is electrically insulated from the current loop part. The Yocto-4-20mA-Tx can drive any current loop powered from 12 to 24V with a 0.1% accuracy. Icing on the cake, the device can detect if the loop is properly powered or not.
USB cables and enclosures to be ordered separately.
