Description
The mip-T112 was
developed for
the standard 0/4 – 20mA-current- (2- or 3-wire) 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, an
additional external npn transistor allows currents up to 2A. Also the
circuit contains an
adjustable
voltage/current regulator, which
can
supply
and protect the remaining
components
(sensor,
processor, …).
