Kinitics KCA020 Controller

The Kinitics KCA020 shape memory alloy Controller simplifies using Kinitics actuators and pumps by providing an easy to use interface to a PLC. Closed- and open-loop control using one or several inputs allows for a high degree of accuracy and repeatability while maintaining the actuator within recommended safety limits.

Key Features & Benefits

  • ┬áSingle-phase 120 VAC input
  • Compact size, DIN rail mounting
  • Internal temperature protection; fault notification
  • Discrete I/O allows for multiple control strategies

Discrete Inputs:

  • Enable: Driving of the actuator is conditional on the presence of a signal at the Enable discrete input.
  • Single: The actuator will stroke from its present position to its End of Travel position limit, triggered by the End of Travel switch input.
  • Pump: The actuator will stroke from its present position to its End of Travel position limit, triggered by the End of Travel switch input. Once the actuator relaxes to its home position, as indicated by the Home switch, the controller will automatically initiate another stroke to End of Travel. The controller will continue in this manner provided the Pump signal is maintained. A low-voltage, 200 Hz PWM signal can also be used at the Pump input for complex control.

Analog Input:

  • Gain: This 4-20ma input allows complex control of a Linear Actuator or Piston Pump to be implemented. Feedback from a position, force or pressure sensor can be used in the PLC programming to adjust Gain as necessary to, for example, lift a part to a certain position or exert a specific force when holding an object.

Discrete Outputs:

  • Status: Indicates that a signal is present at the Enable input, and the controller is not in an over-temperature condition. The Status LED will switch from red to green to indicate that Status is active.
  • Home: Signals the actuator is in the Home position. The optional Home switch must be installed for this output to function.
  • End of Travel: Signals the actuator has reached its End of Travel.
  • Fault: Signals an error condition has caused AC voltage to be present at the load when the controller is in the off-state (not enabled, or an over-temperature condition is present). This indicates, for example, a MOSFET failure and shorted load.
