netlinx®control cards and net modules
NetLinx Control Cards serve as flexible, modular building blocks for cre-
ating advanced control applications. Up to 12 Control Cards can be
inserted into the NetLinx CardFrame’s front-access control slots, or sup-
plied in a NetModule enclosure for stand-alone operation. Control Cards
can meet a wide variety of control needs, including multi-port RS-
232/422/485, IR/Serial, Input/Output, Relay, Voltage, and Volume control.
Every Control Card includes a full array of LED status indicators at the
front, easily viewable from the NetLinx enclosure’s translucent cover.
Whether in a CardFrame or NetModule, NetLinx Control Cards operate
directly on the high-speed ICSNet data bus.
