NI Switch Health Center
To simplify relay maintenance and increase reliability in high-channel-count systems, the NI 2817 is supported in the NI Switch Health Center. The NI Switch Health Center verifies the condition of each relay by sending a signal through a combination of routes, alerting users if a relay has failed stuck open or closed. The NI Switch Health Center also displays relay count information for each relay.
