Yocto-4-20mA-Rx

€87.00
Tax excluded 3-5 days

Small USB module to read very precisely the output of two 4-20mA sensors. The device can convert the current measure to the equivalent physical measure on the fly, and includes a built-in datalogger. You can add Ethernet, Wireless or GSM connectivity to this device.

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.

USB cables and enclosure to be ordered separately.
