DC TO DC TRANSMITTERS
FUNCTION
The MM4010, MM4050, MM4300 and MM4310 DC to DC Transmitters provide DC output voltages or currents proportional to a DC input signal. They are useful in converting voltages to currents or currents to voltages, in providing signal isolation and in scaling signal levels from one amplitude to another.
DESCRIPTION
A stable amplifier is used to monitor a DC input voltage. For current inputs a shunt resistor is added inside the module to create a voltage level at the amplifier input. A final amplifier produces the desired DC voltage or current output.
The modules include filtering and conditioning to reduce susceptibility to transients and noisy operations.
MM4300 and MM4310 utilize pulse width modulation to develop a pulse train with a duty cycle proportional to input signal amplitude. This pulse train is coupled through a pulse transformer where the duty cycle data is converted to a proportional DC level in the output circuit.
A wide range input option adds an 10 position DIP switch which provides input voltage and current range selection by connecting any of 6 gain-setting and 2 current-shunt resistors.
MODEL NUMBERS
Transmitters are available with or without input isolation and with standard or narrow spans. The narrow span models use a superior, low drift input amplifier. Model numbers are as follows:
MM4010 Standard spans, nonisolated
MM4050 Narrow spans (below 50 mV), nonisolated
MM4300 Standard spans, input-ou...
