Common FAQ

Can I hot-swap this terminal block while the system is powered?No. Removal or insertion of the KJ4001X1-CJ1 must only be performed when the system power is de-energized. This ensures protection against electrical surges and maintains safety in hazardous environments.

What is the purpose of the rotary keying system?The terminal block features mechanical "keys" that must be set to match the specific I/O card (e.g., DI or DO 32-channel cards). This physical safeguard prevents a user from accidentally plugging a 32-channel I/O card into a terminal block wired for a different voltage or signal type.
