Replacement terminal board suitable for POWEROL-60 central roller motors. This board performs two functions:

• It interrupts the power supply to the motor when the corresponding limit switch is activated (i.e., the limit switch for the fully open or the limit switch for the fully closed position). These two limit switches are integrated onto the board and the current flows through them for the opening and closing movements respectively.
• It sends a signal (electrical) to unlock the motor's electromagnetic brake for as long as the motor is operating (i.e., as long as one of the two limit switches is not pressed).
