PM564-R-AC, article 1TNE968900R1220, is an AC500-eCo programmable logic controller for direct 100 to 240 V AC supply. Its integrated signal set combines six 24 V DC digital inputs, six relay outputs, two analog inputs and one analog output.

This original fixed-terminal version is distinct from later PM564-RP-AC pluggable-terminal hardware. The terminal construction, AC supply and mixed onboard I/O must all be matched when servicing an installed controller.

• Runs compact machine logic from 128 kB of program memory.
• Accepts a wide-range 100 to 240 V AC controller supply.
• Reads six 24 V DC digital inputs together with two onboard analog inputs.
• Switches six relay outputs for loads within the documented 120/240 V AC, 2 A ratings.
• Provides one onboard analog output for a configured machine signal.
• Supplies 24 V DC auxiliary power up to 180 mA for suitable input-side use.

• Fits compact standalone control panels that can supply the controller directly from 100 to 240 V AC.
• Integrates digital, relay and analog signals where a separate local I/O set would add unnecessary panel space.
• Supports local S500-eCo expansion when the application exceeds the onboard channel count.
• Requires the exact fixed-terminal wiring pattern to be retained during a like-for-like service exchange.
• Can be evaluated for migration to a newer AC500-eCo V3 controller after signal type, relay load and supply conversion are reviewed.

• Compact machine panels supplied from 100 to 240 V AC.
• Standalone controllers that need relay outputs together with onboard analog signals.
• Small material-handling, packaging or auxiliary-process control stations.
• Maintenance of an installed fixed-terminal PM564-R-AC with a preserved application backup.
• Legacy AC500-eCo systems being assessed for a staged V3 platform migration.

What distinguishes PM564-R-AC from PM564-RP-AC?

PM564-R-AC is the original fixed-terminal 1TNE version, while PM564-RP-AC uses pluggable terminals and a different ABB article number.

Can the CPU be powered from 24 V DC?

No. This AC variant is designed for a 100 to 240 V AC input supply; the 24 V DC terminal is an auxiliary output within its stated limit.

How many onboard relay outputs are available?

The controller provides six relay outputs for loads within the documented ratings.

Does the controller include analog I/O?

Yes. The onboard set contains two analog inputs and one analog output.

Can external S500-eCo modules be added?

The documented AC500-eCo system supports local expansion with as many as ten modules, subject to configuration and power requirements.

What must be checked before a platform migration?

Review the AC supply, fixed terminals, six relay loads, analog signal ranges, program, expansion modules and any serial communication before selecting new hardware.
