Mighty Module MM4300 DC Input Isolated Transmitter
MM4300 DC Input Isolated Transmitter
The MM4300 provides a DC output, fully isolated from input, line power and ground, proportional to a DC input. It is useful in eliminating ground loops and common mode signals.
The MM4300 include filtering and conditioning to reduce susceptibility to transients and noisy environments. It utilizes pulse width modulation to develop a pulse train with a duty cycle proportional to the 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 circuits.
The wide ranging option (WR) allows a choice of voltage and current input signal selection by the use of an 8 position DIP switch.
The choices of full scale inputs are shown below.
Eliminates ground loops and large common mode signals. Use for voltage/current scaling and conversion with isolation for buffering and noise reduction.
The module is designed to plug into a standard 8-pin relay socket. Part number MP008 is a molded plastic socket suitable for mounting on a flat surface or in a 2 3/4 inch wide PVC snap track (TRK48). Socket DMP008 is a 8-pin DIN rail mounted socket. Use CLP-1 hold-down clip if needed for vibration environment (MP008 only). A Killark HK Series explosion-proof housing with dome and 8-pin socket is available (HKB-HK2D-8).
