CV Inputs and Outputs
CAB 8i CobraNet Input BoB and CAB 8o CobraNet Output BoB
Both the CAB 8i and CAB 8o have eight control voltage (CV) inputs and outputs, plus 8 relay contact points with normally closed, normally open, and common contacts brought out to the rear panel. The CV inputs have a 0 to 10V range, while the outputs are 5V digital TTL outputs. The relay contact closure points come directly from the remote controlled relays, and are of a SPDT configuration.
Analog BoB's
The eight control outputs appear on a separate Phoenix connector on the back of the breakout box. They provide logic outputs from the system. The output voltage is TTL format. Outputs are capable of sourcing 6ma and sinking 20ma while maintaining valid TTL levels.
