12-24V Single Channel Vehicle Loop Detector for Traffic Control The Reno BX-4 by EDI is a high-performance single-channel loop detector designed for vehicle detection in secure access systems. Engineered for 12–24V DC or 24V AC operation, this detector features dual relay outputs, eight selectable sensitivity levels, and multiple output modes - making it an ideal solution for barrier gates, slide gates, traffic lanes, and industrial access points. Equipped with TruePresence™ detection, delay timers, and automatic sensitivity boost, the BX-4 provides reliable performance even in high-bed vehicle and noisy electrical environments. Its fail memory and LED diagnostics allow for real-time fault indication, making troubleshooting fast and efficient. Designed for use in perimeter access and traffic control applications. Mounts in a standard detector rack or surface enclosure. Harness sold separately. Key Features Single-channel vehicle loop detector for access control and traffic systems Dual relays with independently selectable output modes Eight sensitivity levels for fine-tuned detection accuracy TruePresence™ detection holds call output as long as vehicle is present Optional 2-second output delay and automatic sensitivity boost Detect memory retains presence during brief power interruptions Four selectable loop frequencies to avoid cross-talk interference Diagnostic LEDs indicate power, detect status, and loop faults Conformal-coated circuitry for rugged, long-term reliability Technical Specifications Model: BX-4 Power Input: 10–35V DC, 18–32V AC Current Draw: 50–80 mA max Loop Frequency: 20–100 kHz (4 selectable bands) Sensitivity Settings: 8 levels (0.01% to 1.28% ΔL/L) Relay Outputs: A & B, selectable for presence, pulse-on-entry, pulse-on-exit, or fault Presence Hold Options: TruePresence™ or Limited Presence Response Time:
