Yes. We worked with FEDEX/DHL/TNT/UPS/ allowing us to provide swift global delivery of parts to any corner of the world.
Normally 3-5 working days,some remote areas 5-7 days more.
Compact CPU architecture with 512 kB program memory, Ethernet and transistor I/O.
PM556-TP-ETH combines an ARM-based controller, integrated Ethernet and fixed digital I/O in the AC500-eCo form factor for stand-alone machine programs.
A reliable PM556-TP-ETH replacement must preserve the 24 V DC transistor-output configuration, plug-in terminals, controller program and communication settings.
Program capacity, terminal blocks, communications, lifecycle and replacement evidence.
ABB PM556-TP-ETH provides 512 kB of Flash EPROM program memory. Verify the saved application, retained data use and optional accessories before exchanging the CPU.
Match eight 24 V DC digital inputs and six 24 V DC transistor outputs. Relay-output or mixed-analog AC500-eCo CPUs are not wiring-equivalent replacements.
ABB PM556-TP-ETH has onboard Ethernet and an RS-485 COM1 interface. COM1 can be used for programming, Modbus, serial ASCII or CS31 master communication; COM2 requires optional hardware.
No. ABB's latest PM55x/PM56x data sheet lists order code 1SAP121200R0071 in the Classic phase, meaning legacy availability may continue but it is not recommended for new installations.
ABB leaves the possible migration-device field blank for PM556-TP-ETH in the latest data sheet. Any AC500-eCo V3 migration therefore requires an engineering check of program, I/O, terminals and communications.
Provide order code 1SAP121200R0071, nameplate and terminal photos, installed options, application backup status, Ethernet and serial use, quantity, destination and delivery date.

We continue to source discontinued, obsolete, and hard-to-find automation parts from various brands, helping customers maintain existing equipment and reduce downtime caused by spare parts shortages.
Sincere Cooperation, Long-Term Trust
A Russian customer urgently needed a replacement for a discontinued automation component. After reviewing the product label, technical parameters, and application details, our engineers recommended a compatible alternative and provided photos and test videos before shipment. The alternative performed well, enhancing the customer's confidence in our technical capabilities and leading to multiple repeat orders.
An Indian customer still had doubts after initial online communication with us, so they visited our company in person for a face-to-face meeting and product inspection. This visit increased the customer's trust and led to the successful placement of their first order. Over the next few years, we completed multiple orders and established a stable, long-term partnership.
A Venezuelan customer needed a specific automation component and compared products and services from several suppliers online. After nearly three weeks of careful consideration, our sincere communication, professional service, and reliable product quality won the customer's trust. After receiving the product and using it for several weeks without any problems, the customer gave us positive feedback and subsequently placed multiple orders.
