M1151-M10A PROGRAMMABLE RESOLVER DECODER 
MULTI-TURN PROGRAMMABLE RESOLVER DECODER WITH LIMITS 

Reliable Under Extreme Environments
The M1151-MI0A 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 environment, such as mechanical shock, vibration, extreme humidity and temperature changes, oil mists, coolants, solvents, etc., and the programmable unit M 115 1 -M I OA can be mounted up to 2500 ft (762 in) away in a control panel. The ratiometric converter assures high-tracking-speed and high-noise-immunity.

Self- Diagnostics with Healthy Output
The M1151-MI0A is provided with an internal self-check circuit 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-MI0A, 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.
