Model 862 encoder is rated for operation with a 9 to 30V power supply from -40 to +80°C.
So that machine builders can better monitor predictive motion controls, Leine & Linde introduce a new version of a rotary encoder supporting Condition Monitoring Systems. The Model 862 is a heavy duty incremental encoder that further enhances plant efficiency with the PROFIBUS DP communication interface. Leine & Linde’s Advanced Diagnostic System (ADS) includes the PROFIBUS diagnostic information, giving a plant manager insight on the general health of the encoder, as well as specific failure information should such an event occur.
Working in tandem with the traditional incremental output signals, the PROFIBUS communications also supports velocity feedback, over-speed alarm limits, operating temperature, heartbeat counters, position presets, standstill detection and time, count up direction, internal diagnostics, operating time, and encoder configuration details. While the incremental outputs support a wind turbine speed control, for example, the Profibus system can provide the farm operator with higher level information on the overall turbine function.
High Voltage/High Current TTL outputs are provided on the Incremental output channels and the encoder is isolated from the shaft up to 2.5 kV. Hybrid ceramic bearings provide the isolation as well as extended operating life. The encoder is rated for operation with a 9 to 30V power supply from -40 to +80°C.
The unit also provides visual health status for walk-by inspection from two, dual-color LEDs in the housing cover. Through combinations of steady and blinking red-green indicators, encoder power, communication, and workers can verify operational status at a glance.
