Digital Output interface module wiring connections.
Digital Output modules
Unsure of wiring details.
UNC 696/796 controllers provide digital outputs via "Digital Output Interface modules". These modules are connected to the controller either using hard wiring or via a ribbon cable. The UNC 796 is most likely to be connected using "hard wiring", whilst the UNC696 may use a combination of the two.
This controller is contained in a robust metal case and is commonly used in a stand alone situation. The case is sufficiently large to incorporate two "Digital Output Interface modules", these are located internally, one on each side. A ribbon cable is used to connect each module to the motherboard. These modules are associated with the I/O slot 1, I/O's 1-8 being the left module and 9-16 being the right.. These modules can only be used with slot 1, if additional modules are required, they must be hard wired.
Digital Output Interface modules are normally hard wired to the controller slots, ribbon cables can be used, but seldom are.
