ABB 1SAP120800R0001 PM554-RP-AC is a 100-240 V AC AC500-eCo programmable logic controller CPU for compact industrial automation. It executes the PLC application and connects onboard discrete field signals.
- 128 kB Flash EPROM program memory
- 8 digital inputs and 6 relay outputs
- 100-240 V AC wide-range supply
- RS-485 COM1 and I/O-bus expansion for up to 10 I/O modules
The PM554-RP-AC reads eight discrete input channels, processes the configured control program, and switches six relay output circuits. COM1 can serve as a programming port, Modbus master or slave, serial ASCII interface, or CS31 master. ABB lists the MC503 memory card, TA561-RTC, TA562-RS, TA569-RS-ISO and TA562-RS-RTC as usable accessories; select accessories, relay loads and field wiring according to current ABB documentation and the installed system configuration.
Important Notice: Confirm whether pluggable I/O terminal blocks, optional memory, clock and serial modules, manuals, software and other accessories are included in the quotation or stock description.

Important Notice: These are two separate Apter Power documents independently prepared from manufacturer-published ABB information. Confirm the physical nameplate, current ABB documents, and installed-system requirements before configuration or installation. They do not replace official ABB manuals.
AC-powered machine control
Runs compact PLC logic directly from a 100-240 V AC supply in industrial control panels
Discrete signal processing
Reads eight digital field states and switches six relay output circuits
Modbus and serial integration
Uses COM1 for programming, Modbus master or slave, serial ASCII, or CS31 master communication
Expandable automation cells
Coordinates up to 10 additional I/O modules through the local I/O bus
Read the current ABB documentation and control-panel instructions before use. Verify 1SAP120800R0001 PM554-RP-AC from the physical nameplate.
1
Power supply: Use the ABB-published 100-240 V AC wide-range supply and project protective device
2
Temperature: 0 to +60 °C horizontally; 0 to +40 °C vertically with output load reduced to 50% per group
3
Relay outputs: Verify each load, switching requirement and protective device against the current ABB wiring data
4
Enclosure and mounting: IP20 applies with terminal screws tightened; use 35 mm DIN rail or 4 mm screws at 1.2 Nm
5
COM1 and commissioning: Keep the non-isolated RS-485 common-mode range within -8 V to +12 V and confirm wiring, accessories, software and project compatibility
