Allen-Bradley 1336-RFB-30-A-4 Input RFI Filter Module

Allen-Bradley 1336-RFB-30-A-4 — Stop the Clock on Your Downtime, Ship Today

Every minute a 1336 PLUS drive sits offline without its RFI filter, your production line is bleeding money. A failed or missing 1336-RFB-30-A-4 doesn’t just trip an EMC compliance checkbox — it lets conducted interference propagate back onto your supply rail, corrupting analog instrumentation, tripping upstream protection relays, and in worst cases, taking down adjacent drives on the same bus. We’ve seen it. We stock this part specifically because we know what a 48-hour wait costs a plant manager.

We ship from Xiamen, China. DHL Express to most destinations in Europe, Southeast Asia, and the Middle East lands in 3–5 business days. North America typically 5–7. We cut the paperwork the same day you order. If your line is down right now, skip the cart and call us directly.

Troubleshooting & Replacement Tips

The 1336-RFB-30-A-4 fails in predictable ways. Here’s what I see in the field and how to handle each scenario fast:

Fault Code F002 / F005 on the 1336 PLUS HIM: These ground fault and overcurrent faults are frequently misdiagnosed as drive board failures. Before you condemn the drive, disconnect the RFI filter and megger the input terminals to ground. A shorted Y-capacitor inside a degraded filter reads as a ground fault to the drive’s protection circuit. Swap the filter first — it’s a 20-minute job versus a 4-hour drive swap.

Replacement Procedure (field-verified):

1. De-energize the drive and verify zero voltage at L1/L2/L3 with a calibrated meter. Lock out / tag out per your site LOTO procedure.
2. Photograph the existing wiring before disconnecting — terminal labeling on aged units can be illegible.
3. Remove the four M6 mounting bolts securing the filter to the drive chassis. The filter slides forward off the chassis rail.
4. Transfer the input power leads (L1/L2/L3) and PE ground to the new 1336-RFB-30-A-4. Torque PE lug to 4 Nm — a loose ground defeats the filter’s common-mode suppression entirely.
5. Verify the filter output terminals connect directly to the drive’s R/S/T input terminals with no additional wiring between them. Any added length re-radiates filtered noise.
6. Power up and clear any latched faults via the HIM. Monitor the drive’s input current on the first run cycle — a correctly installed filter shows balanced phase currents within 2% at no-load.

Firmware / Configuration Notes: The 1336-RFB-30-A-4 is a passive hardware module — no firmware, no DIP switches, no addressing. However, if you’re replacing this filter as part of a broader 1336 PLUS II upgrade, verify Parameter 30 (Input Phase Loss Sensitivity) is set appropriately for your supply quality. Overly sensitive settings can cause nuisance trips during filter inrush on power-up.

Common Counterfeit Indicator: Genuine units have a Rockwell Automation holographic label on the capacitor bank cover. The inductors are potted in black epoxy with no visible winding. If you see bare copper windings or a plain silver label, reject the unit immediately.

Reliability in Harsh Conditions

The 1336-RFB-30-A-4 was designed for the same environments where the 1336 PLUS drive operates — and those environments are not gentle. Rockwell Automation’s qualification testing for this filter series covers continuous operation at 40 °C ambient with 95% non-condensing humidity, 2G vibration across 10–500 Hz per IEC 60068-2-6, and 500 V surge immunity per IEC 61000-4-5. The Y-capacitors are rated for 100,000 hours at full voltage and temperature — longer than most drives they’re installed on.

In practice, the units we pull from decommissioned systems after 15+ years of service in paper mills and chemical plants still test within datasheet tolerance on capacitance and insulation resistance. The failure mode when they do fail is almost always a single shorted Y-cap from a sustained overvoltage event — not wear-out. That’s a well-understood, field-replaceable failure, not a systemic reliability problem.

For installations in coastal or high-humidity environments, we recommend applying a conformal coating to the PCB after installation if the cabinet does not maintain positive pressure. The filter’s IP20 rating assumes a clean, dry cabinet interior.
