VersaMax Modules
The NIU provides I/O scanning and a communications interface, allowing a
group of VersaMax modules to function as an I/O station on a communications
bus. The power supply on the NIU provides power for the modules in the I/O
Station. Additional “booster” power supplies can be included in the system if
needed for modules with high current requirements.
A NIU module has connectors appropriate for its communications network type
and status LEDs. NIUs also have rotary dials that can be used to set
communications ID information and other parameters.
