MultiTek DC Linear Integrator Transducer

M100-DI1 Single relay output
M100-DI2 Double relay output

The M100-DI1 is a linear integrator which accepts D.C. Inputs, and integrates the input with respect to time. An ouput is provided via a relay which gives a pulsed output, the frequency of which is directly proportional to the amplitude of the input signal.
One of the main uses of the M100-DI1 is the measurement of Watt and Kilowatt hour. This is achieved by feeding the output of a watt transducer (M100-WA series) into the M100-DI1.
The input signal is integrated against time and the resulting output pulses from the relay are proportional to the kW.h being consumed. These pulses then can be fed to an electromechanical counter, digital counter or a computer, where the kW.h consumed can be stored. Another use is the measurement of Ampere hours.
The M100- DI2 is the same as M100-DI1 with the additional feature of having 2 relay outputs, this allows the user to feed one set of pulses to a counter on a switchboard whilst feeding the other set of pulses to a remote computer in a control room.
