PM564-RP-AC, article 1SAP121100R0001, is an AC500-eCo processor module powered from 100 to 240 V AC. Its onboard I/O consists of six digital inputs, six relay outputs, two analog inputs and one analog output.

The RP designation combines relay outputs with the pluggable-terminal construction. The CPU is supplied without the removable I/O blocks, so one 9-pole and one 11-pole terminal block must be retained or ordered for installation.

• Runs compact AC500-eCo applications from 128 kB program memory.
• Accepts direct 100 to 240 V AC controller power.
• Reads six digital and two analog input channels in the onboard configuration.
• Switches six field loads through relay outputs and provides one analog output.
• Uses removable terminal blocks for serviceable field wiring.
• Supports local AC500-eCo expansion for applications that exceed the onboard channel set.

• Compact machine panels with a 100 to 240 V AC controller supply.
• Standalone automation that needs relay outputs for mixed field-load types.
• Small processes combining digital and analog onboard signals.
• Maintenance of installed AC500-eCo systems using removable I/O terminals.
• Migration studies where an AC-supply relay CPU is being converted to a current 24 V DC transistor-output platform.

• PM564-RP-AC is in ABB lifecycle phase Classic and is principally an installed-base service product.
• Possible migration devices use 24 V DC supply and transistor outputs, so they are not direct electrical replacements for this AC relay model.
• Review the controller supply, six relay loads, analog signals, terminal conversion, application and communication requirements before migration.
• Retain the correct 9-pole and 11-pole terminal blocks for a like-for-like processor exchange.
• Back up the program and validate every onboard channel and relay load after replacement.
