Flap Barrier

The drive mechanism incorporates a torque controlled DC Servo motor using latest PWM Technology to keep pace with upcoming technologies with almost 100% duty cycle & Operating on single arm against retractable barrier. This produces a speed controlled motion. The lever arm can be adjusted so that panels can be opened after certain force is applied at a certain position. In the even of power failure panels can be specified to remain closed (Fail Locked mode) OR Open (Fail Safe mode). The retractable barrier can be operated in normally closed or open mode (Optional), Drive systems incorporate highly reliable torque controlled DC servo motor, Opto-isolated inputs & outputs for interfacing external device.
