Description
1. Product Title
ABB PFSA103D (3BSE002489R1) Integrated Compact PLC Controller with Onboard Mixed I/O, AC500 S500 Series
2. Product Overview
PFSA103D, Order Code 3BSE002489R1 is an all-in-one compact CPU controller belonging to ABB AC500 PLC S500 automation system. It integrates processor, built-in mixed analog/digital I/O points, dual Ethernet ports and S500 local I/O expansion bus in one DIN-rail housing.
It is designed for small & medium standalone machine control, closed-loop process regulation and electronic cam curve positioning control. It can expand up to 10 external S500 series I/O modules via internal I/O bus to enlarge system capacity. The module is galvanically isolated internally, equipped with comprehensive LED status diagnosis indicators for fast on-site troubleshooting. It is a legacy EOL spare part, only used for maintenance replacement on existing ABB AC500 old-generation equipment.
