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