DC20~30V Turnstile Servo Controller RS232, RS485, CAN, Providing Modbus Communication -25~55℃, Suitable For Speed Gates, Wing Gates, And Swing Gates

    This DC20‑30V channel servo controller is a high‑performance servo drive unit specially developed for intelligent pedestrian turnstiles. Equipped with RS232, RS485 and CAN interfaces, it supports standard Modbus communication for seamless connection with access control panels and security management platforms.

    Built‑in high‑security anti‑tailgating control algorithm accurately detects tailgating, reverse passing and loitering to improve site security. With industrial‑grade hardware and wide operating temperature from ‑25℃ to 55℃, it delivers stable performance for speed gates, wing gates and swing gates. Widely used in office buildings, industrial parks, stations, residential compounds and public venues. It features precise position control, smooth gate movement, anti‑pinch protection and fault self‑diagnosis to lower onsite maintenance cost.

Q1: What communication interfaces are available? Can it work with common access control systems?

 A: It comes with RS232, RS485 and CAN ports and supports Modbus RTU. It can connect with most access controllers, facial recognition terminals, visitor systems and security platforms without extra converter modules.

Q2: What can the anti‑tailgating function do?

 A: The high‑security anti‑tailgating algorithm identifies normal single‑person passage, tailgating, forced entry, reverse passing and loitering. When abnormal behaviour is detected, the unit can trigger gate locking, alarm signals and status upload to host system for medium‑to‑high security sites.

Q3: Can this controller be used in outdoor open‑air locations?

A: Operating temperature ranges from ‑25℃ to 55℃ for harsh temperature conditions. However the controller itself has no waterproof housing. It shall be installed inside rain‑proof turnstile cabinets. Do not expose it directly to rain, strong sunlight or heavy dust.

Q4: Will voltage fluctuation affect performance?

 A: Wide DC 20‑30V input tolerates small voltage variation. Built‑in over‑voltage, under‑voltage, reverse‑polarity and over‑current protection prevents hardware damage caused by power supply anomalies.

Q5: Which turnstiles are supported? Can gate speed be adjusted?

 A: Designed for speed gates, wing gates and swing gates. Not suitable for tripod turnstiles or heavy vehicle barriers. Opening / closing speed, buffer force and delay parameters can be modified via Modbus for different site requirements.

Q7: Does it support anti‑pinch protection?

 A: Yes. Real‑time load monitoring stops and reverses gate movement when obstacles are detected during operation to avoid pinch injuries in high‑traffic locations.
