Processor module with fixed I/O and expansion slots
The ABB 1SAP124600R0173 is a PM5082-T-2ETH processor module from the PM5082 series, built for distributed automation. It operates on 24 V DC (20.4 to 28.8 V range) and provides 12 digital inputs, 8 digital outputs rated at 0.5 A each, plus 2 configurable I/O points that can be set as input or output. The module carries 24 MB of application memory and an additional 9100 kB of data memory. Two Ethernet interfaces and three option slots allow for fieldbus adapters or extra I/O modules without changing the main controller.
Integration and mounting considerations
Mounts on a DIN rail and draws power from a 24 V DC backplane or external supply (20.4 to 28.8 V). The three option slots accept PM5082-series communication modules (e.g., PROFIBUS, CANopen) or additional I/O slices. Dual Ethernet ports support line or ring topologies for network redundancy. The fixed 12 DI and 8 DO cover most small-to-medium machine I/O; the 2 configurable points give flexibility for a few extra signals without a separate remote I/O node.
