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.
This device can be connected directly to an Ethernet network using a YoctoHub-Ethernet, to a WiFi network using a YoctoHub-Wireless-g, it can even be connected to a GSM network thanks to the YoctoHub-GSM.
USB cables and enclosures to be ordered separately.
Hi, i need to control a signal generator control mounted on a proportional gas valve, this signal generator need a 4-20mA signal, can connect direcly to the yocto module?
@etnaroaster yes, this is exactly the intended purpose of this device. Just be aware that the device is not designed for explosive atmosphere (not ATEX certified), so don't use it in a place where there could be explosive gas.
Perfect, it's possible to create with your partnership with Artisan Roaster Scope a code to command this module directly from artisan (the button function)?
@etnaroaster Is this gas valve part of a standard roasting equipment or is this a custom setup ? For a custom setup, the requirement might be a bit specific, and I am not sure that the development of Artisan can justify the effort...
This valve part its a piece of a custom setup. Artisan already can control phidget module for control dc servo motor with events/button to setup airflow directly from there
@etnaroaster we just had a short mail exchange with the author of Artisan software, and he is OK to add support for Yoctopuce actuators, including the Yocto-4-20mA-Tx. However he is currently very busy working in a new release so that will not happen before June or July.
oh! Thanks a lot! it's so perfect! We wait the delivery the module to start the first tests with the valve, i keep you updated..
