FQA

Q：What is the output type and logic level of the CT-222H module?

A：The CT-222H is a sourcing-type digital output module with 32 channels of 24VDC output, where the high level is active (output is ON when at 24V).

Q：Can this module directly drive field devices, and what protection mechanisms does it include?

A：Yes. The CT-222H can directly drive field devices such as relays and solenoid valves, and features overcurrent protection, thermal shutdown, short-circuit protection, and overload protection to ensure system reliability.

Q：How can I monitor the status of each output channel, and does the module use electrical isolation?

A：Each output channel has a dedicated LED indicator for real-time status monitoring. Additionally, opto-couplers provide electrical isolation between the internal bus and field outputs, enhancing noise immunity and safety.
