• Yocto-4-20mA-Tx

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 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% accuracy. Icing on the cake, the device can detect if the loop is properly powered or not.

This device can be connected directly to an Ethernet network using a YoctoHub-Ethernet, to a WiFi network using a YoctoHub-Wireless-n and to a GSM network using a YoctoHub-GSM.
