Description
The mip-T113 was developed for the standard 0/4 – 20mA-current- (twice) and voltage (protected) interfaces. The circuit is also suitable as LED driver (brightness control possible) or as controllable current and voltage source.The 20mA current of the interface can driven directly by the circuit, with additional external npn transistors currents up to 2A are allowed. Also the circuit contains an adjustable voltage/current regulator, which can supply and protect the remaining components (sensor, processor, …).
