TSA200 is 0-20mA/4-20mA current loop sensor with digital output interface. The current loop input is galvanically 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 a 0-20/4-20mA output. Output readings in mA can be converted to other units, using offset and multiplier of the 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 a daisy chain of multi-sensor systems. It is supported by TCW240B, TCW220 and TCW241 Ethernet controllers.
