PAC SIMULATOR has the ability to interact with a pneumatic controller/driver in order to simulate a real system. It can record signals and send them via CAN lines for monitoring.

PAC Simulator is laboratory equipment that should imitate two pneumatic actuators and provide LVDT signals according to actuator currents. It should contain four "solenoid" circuits performed by dummy load - R-L serial network, two for each actuator. The simulator should measure current in each "solenoid" load and provide LVDT outputs according to those measurements. The LVDT outputs are derived from sinusoidal reference signals that are externally provided to simulator.


The simulator should contain three differential analog inputs:

  • One input for pressure measurement
  • Two loads as will be described later.


The simulator contains two floating communications: CAN and RS422.

  • The CAN communication will be used for continuous transmission of measurements output. Every 2msec the CAN shall output messages with measured currents, and LVDT positions.
  • RS422 will serve for user commands, parameters, and software down-load.


The simulator shall consume mains power 220VAC 50/60 Hz.

LEDs on the simulator front panel shall indicate power on, program running, and error.
