Transmitter open-circuit protection output

2015-06-03View Original

Thread Content

Gentlemen, transmitters often come equipped with circuit-break protection for their output. What is the reason for this? If the power supply is interrupted, the circuit is cut off – so what needs to be protected?

Is the poster referring to the high/low alarm outputs of those transmitters at 3.6mA and 21.6mA?
