Description

This newly developed interface card of Loop-AM3440 Dry Contact card is ideal for collecting alarm inputs from
non-SNMP devices and issuing the information via SNMP trap. The dry contact card has a power relay and can
power up or power down those same devices in the event that one of them has failed for some reason or needs to be
shut off or restarted. The power relay can also be used to switch circuits in cases where the network system
architecture is flexible.
