FAQ
Q1: Does the breakout board support shield/ground termination?
A1: Yes. The shield connection of the DB9 interface is routed to a dedicated terminal point for proper grounding inside industrial control cabinets.
Q2: Can the board withstand industrial vibration?
A2: The KPRH72mm housing and screw terminal system provide excellent mechanical stability. When properly mounted to a 35mm DIN rail, the module remains secure under normal industrial vibration conditions.
Q3: Does the module support hot-swapping?
A3: The DB9 breakout board itself is passive and can be connected or disconnected freely. However, whether your system supports hot-swap depends on the equipment connected to the DB9 port.
