FQA

Q：What does the DT-7221 module do?

A：The DT-7221 is a dual-purpose power expansion module that provides both system power (5VDC/2A) for internal logic circuits and field power (up to 8A) for external I/O devices in an industrial remote I/O system.

Q：Does the DT-7221 need to be configured, and does it occupy a slot in the chassis?

A：Yes, the DT-7221 must be included in the system configuration and occupies one module slot in the I/O chassis. Proper configuration ensures stable power distribution and system compatibility.

Q：What are the output specifications of the DT-7221 power expansion module?

A：The module delivers 2A at 5VDC for system power and supports up to 8A of current for field power, making it suitable for powering multiple field devices such as sensors, actuators, and relays.
