Product Details

  • CJ1 Input Output Control Module (CJ1GCPU45H)
  • Manufacturer: Omron
  • Series: CJ1

Product Description

The Omron CJ1G-CPU45H (CJ1GCPU45H) is a CJ1 series input output control module with 1,280 loop points. This control module has a program capacity of 60,000 steps. The data memory capacity is 128,000 words which are divided into 32,000 words for the DM (data memory) and 32,000 words times 3 banks for the EM (extended memory).

In the Omron configuration, the CJ1G-CPU45H input output control module needs to be connected with a power supply and multiple serial communication modules. The serial communication control modules and the CPU may connect with various protocols and systems like the host link, custom, protocol macros, the 1:N NT links, and the peripheral bus. These protocols and connections permits it to connect with an operator interface terminal, a host computer, programming consoles and the CX-programmers, protocols, position, and microcomputer, and other PLC devices. However the CJ1G-CPU45H can use a peripheral bus and an NT link.

The CJ1G-CPU45H input output control module has two ports in which the CPU can connect with different protocols and devices. The two ports are the peripheral port and the RS-232C port. Then, there is a memory card connector which has an eject button, power switch, and an indicator. The power supply switch insures a safe withdrawal of the memory card from the module by disconnecting the power being fed to the card. The indicator, when green, denotes that power is being supplied to the card and it is lit orange when the card is being retrieved.
