Description
The mip-S112 was developed for sensor supply and signal amplication. The circuit contains an instrumentation amplifier (wired operation amplifier) and the standard 0/4 – 20mA-current- (2- or 3-wire) and voltage (protected) interfaces. 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, …).
