MUX configurations possible:
The MUX module comprises 16 banks of 8 commoned relays. The commons are brought out to the external connector and can be linked to provide any MUX combination of: 128:1 to 16:8.
Up to 7 modules can be combined under software control to provide a maximum of -
896:1, 448:2, 224:4, 112:8, 56:16, 28:32. Multiplexer configurations
This relay module has been optimised for high voltage switching. It can be supplied with alternative relays, optimised for low voltage, low EMF, low capacitance or low contact resistance relays.
System flexibility is also enhanced by the ability to mix module types within a single chassis.

Digital Input / Output module.

External Relay Driver
This module will allow up to 16 external power relays to be controlled. The card also includes monitor contact feedback connections for completing control loops.
