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.
330101-00-77-20-02-05 specifies this 3300 XL 8 mm proximity probe configuration featuring a fully threaded 3/8-24 UNF steel body, a 7.7-inch overall case length, a 2.0-meter total cable length, and standard coaxial ClickLoc connector with CSA/ATEX/IECEx hazardous area agency approvals. This unarmored, non-contact eddy-current displacement sensor is used in 3300 XL monitoring systems for shaft vibration and axial position measurement.
This specific configuration differs from other variants in the 330101 series through its exact combination of a 7.7-inch fully threaded case (Option B: 77) and 2.0-meter cable length (Option C: 20) with no unthreaded section (Option A: 00). It pairs with a 3300 XL Proximitor sensor and an extension cable to form a complete 3300 XL 8 mm transducer system, interfacing directly with 3500 rack I/O modules.
| Option Segment | Code on This SKU | Description |
|---|---|---|
| Orderable Part Number | 330101-00-77-20-02-05 | 3300 XL 8 mm Proximity Probe, 3/8-24 UNF thread, without armor |
| A - Unthreaded Length Option | 00 | 0.0 in (fully threaded body) |
| B - Overall Case Length Option | 77 | 7.7 in (7.7 inches case length) |
| C - Total Length Option | 20 | 2.0 meters (6.6 feet) |
| D - Connector and Cable-Type Option | 02 | Miniature coaxial ClickLoc connector, standard cable |
| E - Agency Approval Option | 05 | CSA, ATEX, IECEx Approvals |
| Manufacturer | Bently Nevada |
| Part Number/Model | 330101-00-77-20-02-05 |
| Probe Diameter | 8 mm |
| Measurement Type | Displacement (proximity) |
| Operating Principle | Eddy current |
| Probe Resistance (R_PROBE) | 7.88 +/- 0.50 ohms (for 2.0 m length) |
| Operating Temperature Range | -52 degC to +177 degC (-62 degF to +350 degF) |
| Environmental Protection | Viton O-ring pressure seal between probe tip and case |
| Dimensions | 45 mm x 95 mm x 95 mm (H x W x D) |
| Weight | 0.14 kg |
During installation, mount the probe with the appropriate probe gap as specified by system calibration. Route the coaxial cable using proper shielding and grounding practices standard for machinery vibration monitoring systems. Avoid exceeding the maximum thread engagement lengths (0.563 inches for 3/8-24 UNF threads) to prevent binding or damage to the probe casing during installation.
The 330101-00-77-20-02-05 configuration includes the Option 05 agency approval package. This certifies the probe for use in hazardous areas under the following approvals:
