Performance & Hardware Specifications

High-Speed Backplane Sync & Firmware Validation

The processing unit coordinates internal operations through high-speed backplane bus communication velocity protocols. Real-time tasks achieve precise deterministic synchronization across expansion racks without cycle time jitter. Built-in system flash controllers ensure full firmware flash compatibility while executing rapid memory transfers across I/O density scaling routines.

Package Configuration

• 1 x Omron CJ1H-CPU65H CPU Processor Unit
• Protective anti-static terminal wrapper

Physical Mounting & Wiring Protocols

• CPU Rack Assembly
  • Lock unit securely onto the DIN rail or rack base by engaging the upper and lower locking sliders before applying system power.
• Expansion Connection
  • Install official expansion bus cables to connect the CPU rack with expansion racks; keep total bus cable length within standard limits.
• Shield Termination
  • Connect functional ground terminals on the power supply unit directly to a single-point cabinet ground rail using low-impedance copper wire.

Technical Support FAQ

• What is the execution speed for basic logical instructions?

  The processor executes standard LD instructions in 0.02 us.

• What maximum I/O capacity is supported by this central processing unit?

  The unit directly manages up to 2560 total local and expansion I/O points.

• How many total units and expansion racks can be connected?

  The controller supports up to 40 Mountable Units across a maximum of 3 Expansion Racks.

• What memory structure is available for user program storage?

  The controller provides 60 Ksteps of program capacity alongside 128K words of Data Memory.

• What current does the processor draw from the internal 5 VDC bus?

  The central processor unit draws 0.99 A continuous current from the internal 5 VDC bus line.

• Does the CPU support hot-swapping or live extraction during operation?

  System backplane power must be fully switched off before extracting or inserting the processor card.

• How are user program memory contents maintained during power loss?

  Data retention relies on internal battery backup and permanent non-volatile flash storage.

• What environmental operating temperature limit must be maintained?

  Ambient enclosure operating temperatures must be kept strictly between 0 deg C and +55 deg C.
