- CJ1 Input Output Control Module (CJ1MCPU21)
- Manufacturer: Omron
- Series: CJ1
Product DescriptionThe Omron CJ1M-CPU21 (CJ1MCPU21) is a control module with input output points from the CJ1 series. This control module has an input output capacity of 160 points per 10 units (and no expansion rack). There are 10 built-in input points and 6 output points within the CJ1M-CPU21 control module. There are 2 counter inputs and 2 pulse outputs. The program capacity is 5k steps and the data memory capacity is 32k words. There is no extended memory (EM), so the data memory (DM) is also 32k words. The current consumption is 640mA when the voltage is at 5V.
The CJ1M-CPU21 input output control module has 288 tasks, 32 of which are cyclic tasks and 256 interrupt tasks. Yet, all the interrupt tasks can be counted as ‘extra cyclic tasks’, this means that technically all the tasks can be called 288. There are four interrupt tasks and each can have a designated number of tasks. There is 1 power OFF interrupt tasks, 2 scheduled interrupt tasks, 32 I/O interrupt tasks, and 256 external interrupt tasks.
The CJ1M-CPU21 has the 40 pin built-in input output besides its two ports. The RS-232C port that uses protocols: host link, NT link, 1:N, no-protocol, or peripheral bus. This port can connect to host computers, and other programming devices and apparatuses (debarring programming consoles). The peripheral port can also connect with programming devices but it also may become an RS-232C by the connection of a converter cable like the CS1W-CN118 or CS1W-CN26. The CJ1M-CPU21 is also supplied with input output indicator lights, denoting whether the built-in outputs and inputs are ON or OFF.
