The ABB PM5650-2ETH 1SAP141000R0278, also cataloged as the PM5650-2ETH Processor Module, operates as a dedicated hardware component for central application processing and fieldbus routing within AC110/160 system architectures.

Functional Designators & System Architecture

The ABB PM5650-2ETH 1SAP141000R0278 incorporates hardware interfaces and processing capacity for real-time automation tasks:

• PM5650-2ETH: Core model code defining CPU performance, dual Ethernet ports, and onboard diagnostic display screen.

• 1SAP141000R0278: Primary manufacturing part number and exact spare order reference.

• Dual Ethernet Interfaces: Integrated RJ45 ports supporting independent IP addresses and field network protocols.

• Serial & Fieldbus Ports: Dedicated RS232/RS485 and CAN serial interfaces for external device communications.

Core Electrical & Operating Parameters

High-Speed Deterministic Networking & Logic Execution

The module coordinates industrial bus data exchanges across local and distributed subracks. Internal backplane bus communication velocity handles continuous input/output register updates, while Profinet or EtherNet/IP deterministic networks process high-throughput field device data. Complete firmware flash compatibility across network nodes maintains deterministic cycle times, non-volatile RAM data retention, and instant fault detection via the onboard display screen.

Standard Delivery Configuration

• 1 x ABB PM5650-2ETH 1SAP141000R0278 Processor Module

• 1 x Anti-static protective wrapping

• 1 x System installation and terminal pinout sheet

Subrack Mounting & Cabinet Integration Rules

• Power Supply Verification: Ensure external DC power supply lines deliver between 20.4 VDC and 28.8 VDC before powering the module.

• DIN-Rail Attachment: Snap the module firmly onto standard 35 mm DIN rails until the rear locking spring latches completely.

• Communication Cable Shielding: Use shielded twisted-pair cables for Ethernet, CAN, and RS232/485 serial buses, grounding shields at the entry panel.

• Hot-Swap Restrictions: De-energize 24 VDC terminal supply lines prior to extracting or inserting the CPU module to prevent serial port arcing.

Frequently Asked Questions

• What supply voltage range is required to power the PM5650-2ETH processor?

  The unit operates on a 24 VDC nominal supply with an allowable operational input range of 20.4 to 28.8 VDC.

• What memory capacity does the PM5650-2ETH 1SAP141000R0278 module provide?

  The unit features an 80 MB total memory allocation, incorporating 369256 kB RAM dedicated to user data execution.

• Which serial and fieldbus interfaces are physically integrated into the module?

  The processor features two Ethernet ports, one configurable RS232/RS485 interface, and one CAN bus communication port.

• Can the PM5650-2ETH processor be hot-swapped while 24 VDC power is applied?

  No. The 24 VDC terminal power feed must be completely isolated prior to mounting or dismounting the processor unit.

• How are real-time CPU diagnostics viewed directly on the hardware?

  System diagnostics, operating status, and error fault codes are shown directly on the front-facing display panel.

• What factory spare part code corresponds to the PM5650-2ETH module?

  The official spare part reference code for ordering this hardware assembly is 1SAP141000R0278.

• How is proper chassis grounding ensured when mounted on a DIN rail?

  Integrated rear metal grounding contacts establish electrical earth continuity automatically when snapped onto a grounded 35 mm DIN rail.

• What is the total package weight for the PM5650-2ETH processor unit?

  The net weight of the processor unit itself is 0.14 kg, providing a lightweight form factor for panel mounting.
