Mighty Module MM4380A DC Input, Field Rangeable, Isolated Transmitter
MM4380A DC Input, Field Rangeable, Isolated Transmitter
The MM4380A provides a DC output proportional to a DC input. The output is fully isolated from input, line power and ground. The unit is useful in eliminating ground loops and common mode signals
Input and output ranges are fully user-settable. Each may be voltage or current, with or without offset. The output response may be normal or reverse-acting. A fully-labeled set of jumpers selects the input and output ranges. The MM4380A is identical in size and fully interchangeable with fixed-range Module such as the MM4300 and MM4300A.
The MM4380A includes filtering and conditioning to reduce susceptibility to transients and noisy environments. It utilizes a feedback VCO to develop a pulse train with a duty cycle proportional to the input signal amplitude. This pulse train is coupled through a pulse transformer to the output circuitry, where the duty cycle data is converted to a proportional DC output level.
Eliminates ground loops and common mode signals. Use for voltage/current scaling and conversion with isolation for buffering and noise reduction. Single-unit replacement module provides field rangeability for all normal input and output ranges.
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).
