Drive Accessories

This category covers Allen-Bradley drive accessories supporting variable frequency drive installations, including signal conditioning modules, isolation transformers, and drive-specific expansion hardware. Bulletin 1321 isolation transformers appear prominently across a wide kVA range — from 7 kVA through 440 kVA — with both 460V and 575V primary configurations, serving as line reactors and input/output conditioning components for drive protection and harmonic mitigation. The 1440 XM Series modules, including the XM 441 Expansion Relay Module and XM 124 Dynamic Measurement Module, are used for machine condition monitoring and vibration sensing in drive-based motion systems. 1336 STEF/QOUT output transistor assemblies and Frame F components round out the selection for legacy 1336 drive repair and replacement needs. Controls engineers sourcing drive support hardware, transformer kits, or condition monitoring modules will find relevant catalog numbers throughout.
