FAQ
Q: Can this module handle external Sequence of Events (SOE) clocks?
A: Yes. If SOE functionality is required, ensure the clock master, clock slave, and the NIMs with SOE requirements are pinned for external clock use. Other nodes remain pinned for internal line-frequency clock.
Q: How does dual-node redundancy improve reliability?
A: Each node can independently supply power. If one node fails, the second node automatically takes over, preventing system downtime.
Q: Is the module suitable for extreme temperatures?
A: Yes. It operates reliably from -40 °C up to +85 °C.
