Winter 2022 & 2023 Q1 Developments in Industrial Automation - expanded product offering and diagnostic and repair services at York MRO

Winter 2023 Update: Since December 2022 the supply chain strictures have fortunately eased, with less stress on product delivery due dates. Our teams at York MRO have been able to ramp up our service response times with expedited shipment schedules back to normal, providing replacement parts and services following normal response times. Our departments are now working on near-normal production levels and our delivery and service schedules back to regular operation levels. In addition to the Struthers Dunn Director 4000 75F77 parts and service support, we have been able to add new lines of product and service:

Expanded Service and Repair Support for New Product Lines: We offer full support for discontinued A-b-Allen-Bradley products, including obsoleted and phased-out Allen-Bradley parts and systems, as well as the all-new for 2023 Control-Techniques product line-up. Starting Q1 2023 York MRO is pleased to announce additional repair and rebuild services for the automation products made by industrial controls leader A-b-Allen-Bradley such as the 900090REV1 spares. Related to this we have added to our service line-up the 8000KRIO manufactured by Allen-Bradley and we are pleased to be able to service most Allen-Bradley systems and parts. Due to increased demand we now feature 95DSC301CAAAA by Manufacturer Control-Techniques as well.
