PM5032-R-ETH is the relay-output standard CPU in the AC500-eCo V3 PM5032 range. Active revision 1 article 1SAP123500R0172 provides 2 MB memory and one Ethernet interface for controller programming and communication.

Twelve digital inputs, six relay outputs and two configurable 24 V DC channels form the onboard I/O set. Two option-board slots and support for up to ten local I/O modules distinguish it from the smaller PM5012 basic CPU.

• Combines twelve fixed digital inputs and six normally open relay output channels.
• Adds two configurable channels that can be assigned as 24 V DC digital inputs or outputs.
• Supports an AC500-eCo V3 I/O bus for up to ten expansion modules within the documented process-data limits.
• Provides two CPU option-board slots for installation-specific extensions.
• Uses a single Ethernet interface for networked controller access.
• Offers compatible replacement from the earlier R0072 device to active R0172 hardware after the required engineering upgrade.

• Standard machine controllers that require more onboard I/O and expansion than a PM5012 CPU.
• Control tasks using relay contacts for mixed load-switching requirements.
• Compact stations extended with AC500-eCo V3 I/O modules on the local bus.
• Panels that require two option boards in addition to Ethernet communication.
• Replacement projects migrating an installed PM5032-R-ETH R0072 CPU to the active R0172 revision.

• Select active revision 1 article 1SAP123500R0172 for current service; R0072 is classified Classic.
• Revision 1 requires V3.6.x-or-later CPU/boot firmware and Automation Builder 2.6.0 or later.
• If revision 0 and revision 1 processors share one application, bring the processors in that application to the required firmware level.
• Archive the project, firmware, Ethernet address, option-board inventory and complete local I/O order.
• Verify relay commons, external protection, terminal set and field wiring before energizing replacement hardware.

How much memory does PM5032-R-ETH provide?

The processor-module description specifies 2 MB of memory.

How many local I/O modules can the CPU support?

The PM5032 processor supports up to ten I/O modules on its local I/O bus within the stated process-data capacity.

Are the six outputs transistor or relay channels?

They are relay outputs; the PM5032-T-ETH is the eight-channel transistor version.

How many configurable digital channels are available?

Two 24 V DC channels can be configured as digital inputs or outputs.

Which revision is active?

Article 1SAP123500R0172 is the active revision 1 product.

What should be reviewed when replacing R0072 with R0172?

Review the Automation Builder version, firmware baseline, project backup, option boards, I/O modules, terminals and relay wiring.
