Real-time clock Battery-backed real-time clock keeps track of time in event of power failure
Battery 10-year Lithium CR2032 battery provides a minimum of 10,000 hours of
data retention during power outages
Protection Incoming power and network connections are protected by non-replaceable
internal solid-state polyswitches that reset themselves when the condition
that causes a fault returns to normal. The power, network, and output
connections are also protected against voltage transient and surge events.
Status indicators LED's indicate status of communications, running, errors, power, and digital
outputs
