C interface (X111) allows for a direct support of:
 Up to 4 DF80xx modules in any combination:
 Up to 4 DF8020 output modules
 Up to 4 DF8040 input modules
 Up to 4 DF8045 supervised input modules (NC inputs)
 Up to 4 DF8046 supervised input modules (NO inputs)
 One DF8090 power supply supervision module
The module can be installed on the DIN-rail, next to the NK823x unit.
DF8020
DF8020 is a module providing 8 relay outputs, NO or NC.
DF8040
DF8040 is a module providing 8 inputs, which can be normally open or normally
closed and driven by dry contacts or open collector signals.
DF8045
DF8045 is a module providing 4 supervised inputs (normally-closed balanced in-
puts).
DF8046
DF8046 is a module providing 4 supervised inputs (normally-open balanced inputs)
designed for migration of CS100/DMS7000 Multiplexer systems with B1G030 line
supervision boards..
