The Yocto-4-20mA-Rx device lets 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 kinds 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 accurate 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 supports 2-wire sensors (powered from the current loop) as well as 3-wire sensors (that require an additional power supply with shared ground) and 4-wire sensors (with an isolated power supply). It can even provide up to 80mA to power 3-wire sensors that do not require too 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-n and to a GSM network using a YoctoHub-GSM.
