Expansion Modules Overview

Up to four expansion modules can be added to the RMC75 motion controller for additional functionality. These modules can be installed in the field.

Module	Description	Usage
D8	Discrete I/O 8 individually configurable I/O	Discrete Inputs and Outputs
A2	Analog Reference 2 Analog Voltage or Current Inputs	Analog Reference Inputs
AP2	Analog Pressure 2 Analog Voltage or Current Inputs	Dual-loop control (position/velocity-pressure/force)
Q1	Quadrature Encoder Input	Quadrature Position Reference

Note: It is possible to add more analog inputs than can be assigned to axes. However, it is still possible to view the voltage of the extra analog inputs using the Analog Input Registers. Inputs that are unassigned to axes can have no status bits, error bits, scaling, filtering, etc.
