Control infrastructure for the Swaraj Secutech ST-4 is driven by an industrial PLC-based control unit capable of direct digital and relay integration across perimeter automation networks. It interfaces with external credential verification hardware, including long-range RFID readers, automated number plate recognition (ANPR) systems, push-button consoles, and biometrics.
The control cabinet provides native safety integration through a dual interlock array. Vehicle protection is managed via integrated magnetic loop detector inputs, which signal the bollard to immediately lower or prevent rising when an authorized or transiting vehicle straddles the sensor line. Pedestrian protection is established using external infrared photo sensors (photocells); if an individual or object crosses the beam during an upward cycle, the bollard reverses travel automatically. Manual lowering capability is built into the hydraulic assembly to enable fail-safe manual lowering during power loss or system emergencies.
