Winter 2024 & 2025 Q1 Developments in Industrial Automation - expanded product offering and diagnostic and repair services at YorkXPS

Winter 2025 Update: Since December 2023 the supply chain strictures have fortunately eased, with less stress on product delivery due dates. Our teams at YORK XPS 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 American Dynamics Ad2081 Series Rs-232 Port Expander AD2081 RS-232 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 Modicon products, including obsoleted and phased-out Abb parts and systems, as well as the all-new for 2023 Omron product line-up. Starting Q1 2025 YORK is pleased to announce additional repair and rebuild services for the automation products made by industrial controls leader Modicon such as the AMC986003 spares. Related to this we have added to our service line-up the BRC100 manufactured by Abb and we are pleased to be able to service most Abb systems and parts. Due to increased demand we now feature CJ2HCPU64EIP by Manufacturer Omron as well.
