Connections:
Automation Inputs, Logic Outputs, Monitor Output
The automation inputs, logic outputs and monitor output all use a 2-terminal Euro style
(a.k.a. Phoenix) receptacle. The Automation Inputs can be connected to relay contacts, a
switch or a 10K potentiometer. Logic Outputs are CMOS compatible. And the Monitor
Output is a single-ended balanced impedance source. All connections require a 2-terminal
Euro style plug. The DCP 300 rear panel label provides all necessary signal information.
The negative terminal of each receptacle is at chassis potential.
Relay Outputs
Two relay outputs are provided via two 3-terminal Euro style (a.k.a. Phoenix) receptacles.
Relay contacts are floating and rated for 30 VDC at 1A. Each output includes one common
terminal, one normally open contact (N.O.) and one normally closed (N.C.) contact. These
terminals are labeled “C”, “NO” and “NC”, respectively on the DCP 300 rear panel. When
the relay is not energized, the “C” terminal is connected to the “NC” contact and the “NO”
contact is not connected. When the relay is energized, the “C” terminal is connected to the
“NO” contact and the “NC” contact is not connected.
QSControl Network
Connect one end of a data communications cable terminated with an RJ45 plug into the
“QSControl” receptacle on the rear panel of the DCP 300 product. Ensure that the lock tab
on the cable engages with the RJ45 receptacle on the DCP 300 rear panel connector.
Note: data communications cabling must be rated CAT-3 or better for 10 Mbps network
connections or rated CAT-5 or better for 100 Mbps network connections.
CobraNet Network
Connect one end of a data communications cable terminated with an RJ45 plug into the
“CobraNet Primary” receptacle on the rear panel of the DCP 300 product. Ensure that the
lock tab on the cable engages with the RJ45 receptacle on the rear DCP 300 panel
connector. For systems requiring redundant network connections, connect a second data
communications cable terminated with an RJ45 plug into the “CobraNet Secondary”
receptacle on the rear panel of the DCP 300 product. Note: data communications cabling
must be rated at CAT-5 or better for all CobraNet connections.
