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.
Option 00 (0.0 in unthreaded length), Option 08 (0.8 in case length), and Option 12 (FluidLoc cable with ClickLoc connector) define this 3300 XL 8 mm proximity probe configuration — 330101-00-08-20-12-05. This unarmored, eddy-current transducer has a 2.0 m total length (Option 20) and carries hazardous area approvals (Option 05) for CSA, ATEX, and IECEx installations. It provides non-contact vibration and shaft position measurements by pairing with a 3300 XL Proximitor sensor and extension cable.
Unlike standard configurations with standard cable options, the integrated FluidLoc cable prevents lubricating oil and other process liquids from leaking out of the machine housing through the cable's interior. The short 0.8-inch fully-threaded case length is used in space-constrained bearing housings where mounting depth is limited. The system is fully interchangeable with other 3300 XL components, eliminating the need to match or bench calibrate individual pieces.
This transducer is used for rotating machinery monitoring:
