The M1150-M10 is a multi-turn programmable decoder. It takes the input from a single turn resolver like AVG Automation's series RL100, which is mounted on the shaft of the rotating machinery. The M I I 50-M10 decodes the resolver signals using highly noise immune ratiometric decoding technique, scales the digital data based on the programmed Scale Factor and displays it on the front panel. The position information is also made available to the output port in BCD format for connecting to a remote display or a PLC The position information is continuously compared to two programmable preset limits and the outputs are activated when limit conditions are satisfied. All outputs of the M I I 50-M 10 are optically isolated and the resolver inputs are differential, insuring extremely reliable operation of the unit even in the harshest of industrial conditions.

The M I 150-M 10 will decode the shaft angle to 1/4096th of a revolution (12-bits) and keep track of multiple revolutions. The decoder also features tachometer and motion detector, fractional scaling, preprogrammed preset value with an external trigger, two channels of PLS outputs, full decimal point control, and PLC synchronization/handshaking for the BCD outputs.

Prescalable, Presettable; Yet Absolute

A wide-range of easy-to-set programmable Scale Factors (0.34095.999) eliminates the need of mechanical gear trains and prescales the display to readout directly in engineering units. Any preset number can be jammed into the position "counter by an external signal, thus "offsetting" or "rezeroing" the machine in no time.

The MI150-M10 is unique in that it can be prescaled and preset and still is absolute over the entire range in single-turn operation. In multi-turn applications it keeps track of the TRUE position, if the resolver movement does not exceed half a revolution after power loss.

Simple, Front Panel Programming

The M 1150-M10 is fully front panel programmable for all variables, yet secure against any unauthorized program changes. Opening of an external user-provided keyswitch inhibits any program changes on the front panel.

No Batteries, Nonvolatile Memory

Nonvolatile EEROM memory retains information indefinitely after power loss or machine shutdown, eliminating batteries and related hazards.

Replacing Electromechanical Selsyn Systems

In new installations, the M I 150-M 10, together with AVG Automation's brushless resolver series RL 100, is a 100% solid-state replacement for electromechanical Selsyn systems.

PC-Handshake for PLC Synchronization

On an external command, such as data transfer command from a PLC, the digital shaft angle position can be "frozen" at the input of the PLC. This ensures that the data are not sampled during transition from one angle to the next, and that the PLC always reads valid data. The unit may be set-up in transparent mode using keyboard commands.

Reliable Under Extreme Environments

The M 115 0-M 10 combines the ruggedness of a brushless resolver and reliability of a solid-state control. The resolver can be mounted on a machine shaft in any hostile environments such as mechanical shock, vibrations, extreme humidity and temperature changes, oil mists, coolants, solvents, etc. And the programmable unit, M I 150-M 10, can be mounted up to 2500 ft (762 m) away in control panel. The splash-proof oil-tight front plate of the M 11 50-M 10 unit guarantees perfect operation even in unfavorable conditions like steel mills. The ratiometric converter assures high tracking speed (700 RPM) and high noise immunity.

Built-in Tachometer and Motion Detector

The shaft RPM is displayed continuously on the front panel. The motion detector output is energized when the shaft is rotating within programmed motion limits.
