Drive Accessories

This category covers drive accessories and supplemental monitoring components used alongside variable frequency drives and motion control systems. The current in-stock selection includes the Allen-Bradley 1440 XM Series, specifically the 1440-REX03-04RG XM 442 Over Speed Relay Module, which is designed to monitor rotational speed and trigger relay outputs when preset thresholds are exceeded — a common requirement in machinery protection and drive safety applications. Controls engineers and machine builders sourcing XM Series condition monitoring modules or over-speed protection relays for rotating equipment will find this catalog number available for immediate shipment. Additional drive accessory inventory, including braking resistors, line reactors, and dynamic braking modules from Allen-Bradley and Siemens, may be stocked separately across related categories.
