FAQs
Q1: What is the primary function of the PM5052-R-ETH?
It is a standard processor module in the AC500-eCo V3 series, responsible for executing user programs, managing I/O communication, and handling control logic in compact automation systems. With 4 MB memory, 12 DI, 6 relay outputs, and 3 option slots, it is designed for machine control, building automation, and material handling applications.
Q2: What are the key differences between the PM5052-R-ETH and PM5052-T-ETH?
The primary difference is the digital output type. The PM5052-R-ETH (this model) uses relay outputs (6 DO-relay), suitable for switching AC or DC loads directly. The PM5052-T-ETH uses transistor outputs, suitable for high-frequency switching and DC loads only.
Q3: What communication protocols are supported?
The module includes 1 Ethernet interface supporting Modbus TCP/IP . Additional communication protocols (PROFIBUS, PROFINET, RS-232/RS-485) are available via option boards inserted into the 3 option slots.
Q4: What is the lifecycle status of this product?
The PM5052-R-ETH (R0072) is in Classic lifecycle — available from stock but not recommended for new installations. It has been replaced by the Revision 1 version with order code 1SAP124100R0172 (R0172). Revision 1 requires System Firmware V3.6.x or higher and Automation Builder 2.6.0 or later.
Q5: What accessories are required for operation?
The processor module is not delivered with terminal blocks. A terminal block set must be ordered separately: TA5212-TSCL (screw type) or TA5212-TSPF (spring type) for PM5052 series . A micro memory card is optional for data storage.
