POSITION CONTROLLER TYPE CON102

FEATURES :

  • Impulse signals for FORWARD and REVERSE movement of actuating motor.

  • 4-20 mA current input or 0-10V voltage input.

  • Adjustable DEAD-ZONE.

  • 10-turn potentiometer for selection of desired position.

  • Adjustable pulse duration and repetition rate.

  • Panel mounting construction.

  • Push-buttons for manual inching.

 

OPERATION :

  • The Position controller Type CON102  is designed to deliver the control signal to the starter of a 3-phase A.C.  actuator motor.

  • The control signal is delivered through NO contacts of two Electro-magnetic control relays. ( Please see the Block Diagram).

  • The contacts of both the relays RL1 & RL2 can be used to cause FORWARD and REVERSE movement.

  • The input to the instrument may be 4-20 mA current or 0-10V voltage which is compared with a voltage proportional to the desired position .

  • If the actual position is less than the desired value the relay RL1 starts closing itís contacts to cause inching of the motor in the FORWARD direction until the desired position is reached within permissible DEAD ZONE.

  • If the actual position is more than the desired value the relay RL2 starts generating similar control signal to cause REVERSE inching.

  • The duration of the impulse can be adjusted to get an optimum inching  movement.

  • The repetition rate of the impulse can be adjusted to take care of the delay in the overall system.         

 

SPECIFICATIONS  :

  • Accuracy                                :    +/- 1%

  • Temperature Range                :    0-50  C

  • Output                                     :   Through  2 No. Control Relays with contacts suitable for 5A at 250V
