This is the device used to transmit data from a sensor over the two-wire current loop. There can be only one Transmitter output in any current loop. It acts like a variable resistor with respect to its input signal. and is the key to the 4-20mA signal transmission system.

TSA200 is 0-20mA/4-20mA current loop sensor with digital output interface. The current loop input is galvanic isolated from the digital output. The device communicates over a 1-Wire bus. Each sensor has a unique 64-bit serial code, which allows multiple sensors to be connected on the same 1-Wire bus.

TSA200 can be connected to almost any industrial sensor with 0-20/4-20mA output. Output readings in mA can be converted to other units, using offset and multiplier of controller. The sensor can be used for measuring of electrical and non electrical parameters – liquid levels, air pressure, gas concentration, illumination, acidity (pH) etc. It is a passive device, for some applications external DC power supply will be needed – typically 12/24/36VDC.

0-20mA/4-20mA current loop sensor TSA200 utilizes two RJ11 connectors for daisy chain of multiple sensor systems. It is supported by TCW241 Ethernet controller.
