Mechanical Mounting & Wiring Specifications

DIN-Rail Installation Procedures

• Mount the unit on a standard 35 mm DIN rail (TH35-7.5 or TH35-15) inside an IP54 rated industrial enclosure.
• Ensure a minimum mechanical clearance of 25 mm around top and bottom ventilation slots for optimal thermal convection.

Power Supply & Grounding Limits

• Connect incoming 24 VDC control power within the 20.4 to 28.8 VDC tolerance range.
• Use shielded twisted-pair cabling for the integrated Ethernet port, attaching the cable shield directly to the functional earth rail to prevent EMI interference.

Technical Support FAQ

• Is hot-swapping supported for the PM590-ETH CPU module on the backplane?

  No, power off the 24 VDC supply before removing or inserting the processor module to prevent electrical damage to internal components.

• What voltage range can be safely applied to the 24 VDC power terminals?

  The module operates strictly between 20.4 VDC and 28.8 VDC, incorporating a 24 VDC nominal line rating with plus or minus 20 percent tolerance.

• What degree of isolation is provided for signal protection?

  The CPU provides 1500 VAC galvanic isolation to protect logic circuits against line surges and ground loops.

• How is user data stored inside the memory subsystem?

  User data utilizes 3072 kB of RAM, backed up by battery or internal capacitors to retain process values during power down.

• What is the typical thermal dissipation load of this processor?

  The module consumes approximately 6 W under nominal operational conditions at 24 VDC.

• Can the integrated Ethernet port handle standard network cables?

  Yes, standard RJ45 industrial Ethernet cables with CAT5e or CAT6 STP specifications are recommended.

• Does the device support 32-bit processing execution?

  Yes, the core execution unit features an integrated 32-bit RISC processor designed for fast deterministic logic handling.

• What ambient temperature limits must be observed during operational state?

  The CPU is rated for continuous operating performance within an environment between 0 deg C and +60 deg C.
