Product Details

  • CJ1 CPU Control Module (CJ1HCPU66H)
  • Manufacturer: Omron
  • Series: CJ1

Product Description

The Omron CJ1H-CPU65H (CJ1HCPU65H) is a CPU control module from the CJ1 series. This CPU has a current consumption of 0.99 AMP at a voltage of 5V whose LD instruction time is 0.02ms. Its program capacity is 120k steps and its data memory capacity is 256k words; the data memory can be split between the data memory (DM) of 32k words and the extended memory of 32k words times 7 banks (32 x 7).

The Omron configuration, which the CJ1H-CPU65H control module is a CPU for, needs a memory card attached to the CPU, specifically the HMC-372/672 card. There also must be the CJ1W-PA205R, CJ1W-PA202, or CJ1W-PD025 power supply which is linked to the CPU. Lastly, sundry configuration modules, for instance, the basic I/O, special I/O, and CPU Bus control modules can be fitted into the system with the CJ1W-TER01 end cover placed on either side of the finished configuration. Now the CJ1H-CPU65H can be part of the basic configuration which is simply a power supply and up to ten other control modules, however CPU module can also be deposited on a CPU rack or expansion rack. Either of these racks can be used if more than ten configurations modules are deployed or if the current usage exceeds the capacity that a single power supply can handle. The rack can allow for two power supplies and a divide of the load.

The CJ1H-CPU65H control module being a member of the CJ1H family is useful for devices needing speed and a large memory capacity and is very applicable because of its small size, letting it fit in many places.
