About the Black Box AlertWerks

Expand Environmental Monitoring and Device VisibilityThe AlertWerks Dry Contact Expansion Hub adds 16 Opto Isolated dry contact inputs to the AlertWerks EME164A and EME168A gateways. The EME1DC16 expansion hub connects to the RJ-45 expansion port on the front of the gateway and adds 16 dry-contact inputs.

Multiple expansion hubs can be daisy-chained using the integrated E-In and E-Out ports. Hubs can be extended up to 1000 feet (300 meters) from the AlertWerks gateway or from each other, providing the flexibility to monitor sensors across data centers, warehouses, manufacturing facilities, and other distributed environments.

Built-in graphing tools automatically generate historical reports, while customizable notifications can be delivered through email, text message, SNMP traps, audible alarms, and other methods. Advanced filtering options help reduce nuisance alarms and ensure that critical events receive immediate attention.
