FAQs

What is a Safety Node Unit used for?
It houses safety I/O modules (like emergency stop inputs) and connects them reliably to a central safety controller over a dedicated bus.

What does the "Dual-Redundant Power" mean?
The unit can accept two separate 24V DC power feeds. If one fails, the other keeps it running without stopping the safety system.

Can I use AC power with this model?
No, the suffix code "4" in SNB10D-245 specifies 24V DC input only. You need a different suffix code model for AC power.

What is the included CU2T part for?
It is a connector unit with a built-in terminator for the ESB communication bus. It is required for proper electrical signaling at the end of the bus cable.

How many I/O modules can one node unit hold?
The unit itself is a chassis. The number depends on the modules you install. It is designed to work with Yokogawa's range of safety I/O cards.
