Double power supply input and relay output alarm
IT-ES308-IU series can provide double power supply backup and 1-route relay alarm output. Redundant double DC power supply input (12V～48VDC) can provide your equipment with uninterrupted operation to further provide additional protection for normal operation of automatic system. 1-route equipment alarm output signal can support power supply and port link alarm. Relay can give out output alarm in case of power supply failure or interruption of port link to notice or remind site engineers to make quick response for appropriate emergency maintenance.
