常见问题 (FAQ)
-
Is the TWDDDI8DT module hot-swappable?
No, the module is not hot-swappable. It should be powered down before installation or removal. -
Can I mix input types (sourcing and sinking) on this module?
No, all channels must be wired for the same input type: either sourcing or sinking, depending on your PLC configuration. -
Does the TWDDDI8DT provide diagnostic LEDs for each input?
Yes, each input channel is equipped with an LED indicator showing real-time status (ON/OFF). -
What cable type is recommended for wiring inputs to this module?
Use shielded twisted pair cable to minimize electrical noise and ensure signal integrity. -
Can this module be used in outdoor enclosures?
It can be used in outdoor-rated enclosures with proper environmental protection (IP-rated panel), but the module itself is not weatherpro/. -
What is the maximum wire size supported by the terminal blocks?
The terminals support wire sizes up to 2.5 mm² (AWG 14). -
How does the module handle debounce for mechanical switches?
The PLC s/tware can apply debounce filtering as needed; the hardware has a basic input delay but does not perform advanced debounce. -
Is there a fuse or protection built into each input channel?
There is built-in protection against over-voltage and reverse polarity, but no replaceable fuse is included. -
What is the typical application cycle life / this module?
The module is rated for industrial use with a long operational life, typically exceeding 10 years under standard conditions.
