Analog Position Transmission Module (APTM)

This card features a 4 to 20 mA galvanically-insulated module for position or torque re-transmission. The said card is easily
plugged into the base card without the need for dedicated tools. The module can be configured to the output torque in
place of the actuator position.

Position Servo Amplifier Module (PSM

Module necessary for actuators in modulating and inching duty. It drives the motor through pulses at constant frequency
and duration proportional to the position error, following an externally-set analogical point signal.
