7 Hardware
The axis modules have one input per axis for interfacing to transducers and one Control
Output per axis for interfacing to an actuator. Axis modules are either one or two axes.
Each axis module interfaces to a different type of transducers.

Optional Expansion Modules
Up to four optional expansion modules can be added to enhance the capabilities of the
RMC70. These modules can be field-added. Expansion modules can be used for reference
axes, pressure control, or discrete I/O.
