Implementing 3-Switch XOR Ladder Logic with Internal Bit
Implement a 3-SPST switch XOR light circuit in LogixPro or RSLogix 500 using an internal relay bit. Includes truth tables, boolean equations, and verified.
Designed for critical vibration and position monitoring in confined machinery spaces, the Bently Nevada 330878-90-00 serves as an essential component of the 3300 XL NSv Proximity Transducer System. This high-precision Proximitor Sensor processes radio frequency (RF) signals generated by a proximity probe to deliver a voltage output directly proportional to the gap distance between the probe tip and the target. It is engineered specifically for applications requiring tight installation clearances, such as centrifugal air compressors, refrigeration compressors, and high-speed turbomachinery.
The 330878-90-00-2 configuration features a 9.0-meter system length design, optimized for panel mounting within centralized control cabinets. This unit provides stable dynamic and static measurements, ensuring seamless interfacing with Bently Nevada monitoring systems and other machinery protection platforms. By omitting agency approvals, this specific variant offers a highly cost-effective solution for non-hazardous industrial environments.
