Allen-Bradley Pilot Devices & Pushbuttons

Allen-Bradley pilot devices and pushbuttons are catalogued here as one panel-hardware line. It holds 122 catalogued part numbers, all classified as Push Buttons & Pilot Devices, covering operators, pilot lights, selector switches and the mounting and contact-block hardware that goes with them.

Series in this family

• 800 Series Pushbuttons & Selector Switches — 122 catalogued parts across the 800F, 800H, 800T and 800E bulletin prefixes.

The prefix is the practical selector: 800F and 800E are the metric 22 mm ranges, while 800T and 800H are the 30 mm ranges long used on North American panels. Because operators are assembled from an operator, a legend plate and contact blocks, each element carries its own catalogue number — match the complete number stamped on the part you are replacing.

Common Faults

• Capacitor degradation after 7–10 years of service
• Communication errors after firmware drift
• Input/output channel failure from over-voltage events
• Cooling fan failure causing thermal shutdown
• Connector wear in high-vibration installations

Troubleshooting

1. Confirm supply voltage and grounding
2. Inspect diagnostic LEDs and fault codes
3. Verify firmware/configuration matches the application
4. Swap with a known-good unit to isolate the fault
5. Check field wiring and termination

Replacement Options

• Direct OEM replacement (preferred)
• Refurbished OEM unit (cost-effective)
• Compatible cross from the same manufacturer's current catalog
• Equivalent from an alternative manufacturer (engineering review required)

Migration Path

When migrating away from discontinued units, plan for: firmware compatibility, wiring changes, software/configuration migration, spare-parts stock, and field commissioning. Palm Parts Solution can supply both the current generation and stock of the legacy unit while you plan the migration.

Compatibility

Units in this family are compatible with the manufacturer's standard control architecture, communication protocols (where applicable), and accessory ecosystem. Always cross-reference the exact catalog number, firmware revision, and hardware series before installation.
