TERACOM TSA200 – 4-20mA current loop sensor
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 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 multiply sensor systems. It is supported by TCW240B Ethernet controller.
