1-Wire Current Loop Transmitter TSA200

Wire Current Loop Sensor TSA200 Supplier

The TSA200 is a 1-Wire current loop transmitter that accepts input within the 0-20mA/4-20mA range. It's important to note that the current loop input is electrically isolated from the interface.

This device communicates through a 1-Wire bus, and each sensor possesses a unique 64-bit serial code. This feature allows for the connection of multiple sensors on the same 1-Wire bus.

To facilitate the setup of multi-sensor systems, the TSA200 includes two RJ11 connectors for easy daisy-chaining.

This versatile transmitter can be linked to a wide range of industrial sensors with 0-20/4-20mA output. The controller can then convert the output readings from mA to other units by using an offset and multiplier.

TSA200 is suitable for measuring various parameters, both electrical and non-electrical, including liquid levels, air pressure, gas concentration, illumination, acidity (pH), and more.

It's important to note that the TSA200 is a passive device. For certain applications, you may require an external DC power supply, typically rated at 12/24/36VDC.
