Yocto-4-20mA-Rx

  

The Yocto-4-20mA-Rx device will let you read via USB the instant value returned by any industrial sensor following the 4-20mA standard, as well as record the measures on its internal flash for later retrieval when connected again by USB. The device can automatically map the current reading to a physical measure by applying a proportional rule. The module features two inputs, to connect two independent sensors.

You can find sensors for all kind of physical measures using the standard 4-20mA interface. Transmitting the measure using a 4-20mA current loop makes it possible to get a very precise reading (up to 0.01%), and works even when the sensor is far away from the interface module (several thousands of meters of cable away).

The Yocto-4-20mA-Rx support 2-wires sensors (powered from the current loop) as well as 3-wires sensors (that require an additional power supply with shared ground) and 4-wires sensors (with an isolated power supply). It can even provide up to 80mA to power 3-wires sensors that do not require to much power. The supply voltage is regulated 23V, isolated from the USB bus but common to both inputs.

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.

Is the sensor able to measure values between 0 and 4 mA?

2 - mvuilleu (Yocto-Team)Monday,october 05,2015 16H39

@stefan: yes, you can use the whole range 0-20mA if you want, this is a configuration option

Thank you very much!

Hello!

We are thinking about extending our data logger software with support for this device.

If I understood the license terms of your C++ library correctly, it is allowed to embed and distribute your library into (resp. as part of) standard software tools developed by our company. Only executables or libraries are distributed, the source code of the product will not disclosed.

Please confirm if this is OK or let me know a suitable contact on your side to clarify details.

Thanks!

@guenter Yes, this makes no problem: as long as the purpose of integrating our library is to use our devices, you can distribute it the way you want. There is no GPL code in our library.

Yoctopuce, get your stuff connected.
