Expansion Module Description
EXP70-D8 Discrete I/O
Eight discrete I/O individually configurable for any combination of inputs or outputs. Inputs and outputs are 12-24 VDC rated, polarity independent, and optically isolated from controller.
EXP70-AP2 Analog Inputs with Pressure Control and Pressure Limit
Two differential 10 V or 4-20 mA analog inputs for use in position–pressure or position–force control axes. Inputs are 16 bit resolution, and are optically isolated from the controller.
EXP70-A2 Analog Inputs
Two differential 10 V or 4-20 mA analog reference inputs. Inputs are 16 bit resolution, and are optically isolated from the controller.
EXP70-Q1 Quadrature input
Adds one 5 V differential quadrature input for position reference feedback, and a high-speed input for homing or registration. Maximum two Q1s per RMC70.
