The Dataprobe COE-8 is a device for transporting real
world status and switch closure information over any
IP network. The COE-8 system consists of an Input unit
that collects up to 8 status points (wet DC voltage
or dry contact closures) and an Output unit with eight
relays. Upon any change of status of the inputs, a TCP
message will be transmitted to the Output unit, which
will change its relays to match the status of the inputs.
The COE-8 provides a link between older systems, which
commonly use relay alarms, converting them into IP messages
and re-converting them to relay closures at the other
end of the network. This technology reduces the need
for physical, on-site network management, administration
and support by consolidating network equipment located
in numerous remote locations into one central location.
The Dataprobe COE-8 is an ideal solution for a variety
of industries with critical communication needs including
but not limited to broadcast, transportation, energy
management, security and SCADA systems.
The COE-8 contact closure transport system also supports
a one-to-many delivery of switch closures. Up to 32
Output units can be simultaneously notified when an
input state change is detected by the Input unit. A
Web browser interface is used for status monitoring
and setup. Screw terminals are used to connect the inputs
and the outputs. IP addressing is set either manually,
by web browser or DHCP. TCP Port settable for both Web
and control communication. Two level web security is
provided for status monitoring and configuration. Two-level
security allows different users for monitoring and setup.

Bi-Directional Contact Transport
The COE-8 has both inputs and outputs. A pair of
COE-8 units communicate with each other to provide bi-directional
transport of status-to-relay information.
Input and Relay Connections
The COE-8 has 8 inputs and 8 outputs. Outputs are
form C relay contacts. The inputs are simple TTL inputs
that are designed to work with Relay contacts, Open
Collectors, and TTL levels. Each Relay and Feedback
pair are connected using an RJ11 jack on the real panel.
