Allen-Bradley 2094-BC01-M01-S | 480V 9A Servo Module

Description

Key Technical Specifications

Rockwell’s product page identifies the module as a 400/460 V, 6 kW converter, 9 A inverter IAM with Safe Torque Off and lists 2198-D020-ERS3 as the engineering replacement.

The published technical data specifies 324–528 VAC three-phase input, 50/60 Hz operation, a nominal 650 VDC bus, SERCOS III communications, and common-DC-bus capability.

Application Scenarios & Pain Points

When an older production machine contains several Kinetix 6000 axis modules, losing the IAM is more serious than losing one individual axis amplifier. The IAM establishes the power architecture feeding the downstream axis modules, so incorrect substitution can create a system-level commissioning problem.

• Multi-axis servo machinery: Used as the main integrated power module in Kinetix 6000 systems where several axis modules share a common DC bus.
• High-voltage motion systems: The 2094-BC01-M01-S is intended for the 400/460 V-class Kinetix 6000 architecture, rather than the lower-voltage 230 V variants.
• Legacy packaging and material-handling equipment: Appropriate for maintaining older machines where the existing Kinetix 6000 architecture remains operational.
• Machine retrofit projects: The common DC-bus architecture can reduce duplicated power-conversion hardware across multiple axes, but the replacement must be sized against the complete axis load.

Field note: If the replacement IAM repeatedly trips immediately after energization, stop swapping modules. Check the DC-bus load, axis-module combination, motor cabling, ground faults, and input supply first. A downstream short can destroy a perfectly good replacement.

• Allen-Bradley 2094-BC01-M01-S — The exact 6 kW/9 A Kinetix 6000 IAM covered here. It is intended for 400/460 V-class multi-axis systems.
• Allen-Bradley 2094-BC01-M01 — Closely related Kinetix 6000 IAM variant without the “-S” safety designation. Do not substitute it when the installed application requires the Safe Torque Off configuration.
• Allen-Bradley 2094-BC01-MP5-S — Lower-capacity Kinetix 6000 IAM variant. It belongs to the same family but has a different converter/inverter rating and must be sized accordingly.
• Allen-Bradley 2094-BC02-M02-S — Higher-rated IAM within the same Kinetix 6000 family. Useful where the system requires greater power capacity; it is not a drop-in electrical equivalent.
• Allen-Bradley 2094-BC04-M03-S — Larger Kinetix 6000 IAM for higher-power multi-axis installations. Selection depends on the total DC-bus and axis load.
• Allen-Bradley 2094-BMxx-S — Kinetix 6000 Axis Modules that operate downstream of the IAM. These provide individual motor-axis control rather than incoming system power conversion.
• Allen-Bradley 2094-ACxx — Kinetix 6000 AC-input IAM family for other voltage/power configurations. The exact voltage class must match the machine’s electrical design.
• Allen-Bradley 2198-D020-ERS3 — Rockwell’s listed engineering replacement for 2094-BC01-M01-S. It belongs to a newer motion platform, so migration requires an engineering review rather than a simple physical swap.

The Engineer’s Guide: Field Pitfalls to Avoid

⚠️ Do not confuse the 9 A rating with the 6 kW converter rating.

The catalog describes the module as a 6 kW converter with a 9 A inverter. These figures represent different parts of the IAM architecture.

How to avoid it: Size the IAM against the complete Kinetix system and downstream axis-module requirements, not one number from the nameplate.

⚠️ Do not assume 2094-BC01-M01-S and 2094- are interchangeable.

The suffix matters. The “-S” version includes the documented Safe Torque Off functionality.

How to avoid it: Match the complete catalog number and safety architecture before purchasing.

⚠️ Do not ignore Series A/B and firmware details.

Kinetix 6000 documentation distinguishes Series A and Series B drive hardware. Firmware and system configuration also matter when restoring an older motion system.

How to avoid it: Record the exact catalog number, series, firmware revision, controller, SERCOS configuration, and axis-module combination before replacing the IAM.

Frequently Asked Questions (FAQ)

What is Allen-Bradley 2094–S?

It is a Kinetix 6000 Integrated Axis Module used as the main power-conversion module in a multi-axis servo system. Rockwell specifies it as a 400/460 V-class module with a 6 kW converter and 9 A inverter.

What voltage do accept?

The published specification gives 324–528 VAC rms, three-phase, with 360/480 VAC listed as nominal operating values and 50/60 Hz input frequency.

What is the difference between the 6 kW and 9 A ratings?

The 6 kW figure refers to the converter section, while 9 A refers to the inverter rating. They should not be treated as two alternative output ratings for the same function.

still manufactured?

No. Rockwell Automation lists the Kinetix 6000 Integrated Axis Module as discontinued December 31, 2023 and identifies 2198-D020-ERS3 as an engineering replacement.

Can 2198-D020-ERS3 be installed as a direct drop-in replacement?

Do not treat it as a direct plug-and-play replacement. Rockwell calls it an engineering replacement, which means the migration should account for the newer motion architecture, wiring, controller integration, firmware, and application configuration.

Do support Safe Torque Off?

Yes. Rockwell’s product description explicitly identifies the module as having Safe Torque Off, and published technical data associates the Kinetix 6000 safety architecture with SIL 3 and PLe capability.

What should I verify before buying a replacement?

At minimum:

1. Complete catalog number:
2. Kinetix 6000 system architecture
3. Series A or Series B hardware
4. Input voltage and phase
5. Total axis-module load
6. SERCOS configuration
7. Safe Torque Off requirements
8. Existing firmware revision
9. DC-bus condition
10. Factory label and revision
11. Functional load-test evidence
12. Warranty terms and available lead time
