FQA

Q： What types of power outputs does the CT-7221 power supply extension module provide?

A：The CT-7221 provides both system and field power extension: it delivers 5VDC / 2A for the backplane bus and internal logic, and supports up to 8A of field power output for driving external sensors or actuators.

Q：Is software configuration required to use the CT-7221 module?

A：Yes, the CT-7221 must be configured and enabled via the dedicated I/O configuration software to ensure proper power management and seamless integration with the control system.

Q：What application problem does the CT-7221 primarily solve?

A：Designed for high-density I/O systems, the CT-7221 addresses insufficient local power when multiple analog or digital modules operate simultaneously—preventing communication errors or module failures by supplementing 5V system power and extending field power capacity.
