A CAMAC module intended for measurements of instant magnetic field using coil sensor is described. It is four channel integrating ADC with current input in which signal integration time is controlled externally and may be optimized for a given signal. Original technical solution allowing to eliminate influence of the integrator capacity and switches instability on overall accuracy is described. The large accelerator facilities include a great number of magnetic elements interacting with a beam for a short period ranging from 0.01 ms to 10 ms. For example, this class of elements includes all the magnetic components of channels for particle transportation. In addition, most of these elements are operating rarely - once in 1 - 10000 s. For these elements the most optimal is the use of a pulse power supply that reduces the electric power consumption and which is most important, it solves the problem of heat removal. Though, the pulse power supply poses some problems in providing the accuracy of magnetic field and its measurements.
