• Residential automated gates and barriers
• Light-commercial access control points
• Installations requiring integration with safety devices (photocells, edge sensors)
• Systems needing coordinated inputs from remotes, pushbuttons and safety interlocks

Key specifications

• Central logic board for gate and barrier automation
• Multiple control inputs for commands from remotes, buttons and safety devices
• Dedicated outputs for motor control and auxiliary signaling
• Configurable timing and operational parameters for opening/closing cycles
• Terminal layout designed for straightforward wiring and maintenance
• Suitable for use with common residential and light-commercial actuators

How to use

Mount the control unit in a protected enclosure close to the drive unit and power supply, following local electrical codes. Connect the motor outputs, power supply, safety devices and command inputs to the corresponding terminals according to the manufacturer's wiring diagram. Configure timing, travel limits and safety logic using the on-board settings and any available configuration jumpers or DIP switches. After initial wiring, perform functional tests to verify correct responses to open, close and safety inputs before placing the system into regular operation.

Usage recommendations

Use the control unit with compatible actuators and certified safety devices; regularly inspect connections and perform periodic functional tests. Protect the unit from moisture and excessive dust, and ensure a stable power supply to maintain reliable operation.
