M1151-M10A

Simple Front-Panel Programming

TheM1151-M10A is fully front-panel programmable for all variables, and 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 M1151-M10A together with AVG Automation's brushless resolver series RL210 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 in order to ensure that the data is not sampled during transition from one angle to the next, and that the PLC always reads a valid data.

Reliable Under Extreme Environments

The M1151-M10A 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 pro-grammable unit M1151-M10A can be mounted up to 2500 ft (762 m) away in control panel. The splash-proof, oil-tight front plate of the M1151-M10A unit guarantees perfect operation even in unfavorable conditions like steel mills. The ratiometric converter assures high-tracking speed and high-noise immunity.

Self-Diagnostics with Healthy Output

The M1151-M10A is provided with an internal self-check cir-cuit that continuously monitors if the microprocessor is not in reset, input 120 VAC power, DC power supplies, resolver cable, and output-enable circuit. In case a fault occurs in any one of the above critical functions, the unit goes into fault mode and a transistor output changes state from ON to OFF. For fail-safe operation, the healthy output is ON for normal operation and OFF when a fault occurs.

Built-in Motion Detector

Motion detector output is energized when the shaft is rotating in excess of 5 RPM.

Ideal Solution for Shut Height Indication

The M1151-M10A, along with a dual-resolver, provides an ideal solution for shut-height indication. Because of absolute nature of the resolver, the position is retained even during power loss.
