Q: What equipment is this power module used in?
A: It is specifically designed for Omron C200H, C200HX/HG/HE, and CS1 series PLC systems. Installed on the PLC backplane, it provides power to the CPU, I/O modules, and high-function modules. It is suitable for various industrial automation control systems, such as production line control and equipment automation.
Q: How does the system respond after a power outage?
A: According to Omron's official technical specifications, if the power outage time is less than 10 milliseconds, the CPU will continue to run unaffected; if the power outage time exceeds 25 milliseconds, the system will stop running and shut down its output; if the power outage is between 10 and 25 milliseconds, the CPU response is unpredictable. The power outage detection time can be extended through PLC settings (DM 6605).
Q: What are the differences between this model and other similar models (PA204R/PA204S/PA204C)?
A: The main difference lies in the additional functions:
C200HW-PA204: Basic model, no additional functions
C200HW-PA204R: With run output function, it can monitor the PLC's operating status.
C200HW-PA204S: With auxiliary DC24V 0.8A output, it can power external devices such as sensors.
C200HW-PA204C: With replacement notification function, it can prompt when the power module needs to be replaced.
