DIABLO CONTROLS, INC.

Diablo Controls, Inc. is a manufacturer of vehicle detection and access control components, with a product line centered on inductive loop detectors, probe systems, and the racks that house them. The company's catalog includes plug-in and lead-in vehicle detectors, single-card loop racks, and related accessories. These products are used in parking access, gate control, and traffic management systems to sense vehicle presence. Diablo Controls detectors are specified by operating voltage, loop inductance requirements, and physical dimensions. For example, the DSP-7LP operates on 10 to 30V AC with a minimum loop inductance of 20 uH and a 1 1/2 inch overall height. The DSP-15 LVT accepts 10 to 30V AC/DC, also with 20 uH minimum loop inductance, and measures 3 inches in overall height. The DSP-11 LV runs on 10 to 30V AC/DC and measures 3 inches by 1 1/2 inches. The DSP-20 LV operates on 10 to 30V DC and measures 4 inches by 2 inches with a 2 1/2 inch overall height. The DSP-10 117 is a 117V AC unit with 20 uH minimum loop inductance and a 2 1/2 inch overall height. Lead-in detectors, such as the DML-9LP probe kit, operate on 10 to 30V AC/DC and measure 1 1/2 inches by 3 inches with a 1 1/2 inch overall height. Loop racks include the RK-1R, a single card rack measuring 7/10 inch overall length, 3 inches overall height, and 1 1/2 inches overall width, which includes a relay and works with Diablo detectors DSP-40, DSP-50, DSP-55, DSP-13, and AVI-40. The RK1 single card rack is designed for mounting and connecting a loop or free exit probe vehicle detector card, allowing hard wiring of the DSD-13 Tri-Axis Detection System to the control box. These components are typically installed in parking lots, gate systems, and traffic control cabinets. 3G Electric supplies the Diablo Controls line globally, offering access to loop racks, plug-in detectors, lead-in detectors, and probe kits. The product range covers multiple voltage options, including 10 to 30V AC, 10 to 30V AC/DC, 10 to 30V DC, and 117V AC, to match different control panel requirements. Specifiers can select detectors based on loop inductance, form factor, and compatibility with existing Diablo racks and systems. 3G Electric provides technical specifications and part numbers for each item, supporting procurement and integration for maintenance and new installations.

Frequently asked questions

Common questions about DIABLO CONTROLS, INC. from 3G Electric.

What is the difference between Diablo Controls plug-in and lead-in vehicle detectors?

Diablo Controls plug-in vehicle detectors, such as the DSP-7LP, DSP-15 LVT, DSP-11 LV, DSP-20 LV, and DSP-10 117, are designed to plug into a compatible card rack or backplane. Lead-in detectors, such as the DML-9LP probe kit, are intended for direct connection or probe-based installation. Both types sense vehicle presence via inductive loops. Plug-in models typically specify a minimum loop inductance of 20 uH and operate on various voltages, while lead-in models may include a probe kit for specific installation needs. Selection depends on the control panel interface and wiring method.

Which Diablo Controls loop racks are available and what do they support?

Two single card racks are available: the RK-1R and the RK1. The RK-1R measures 7/10 inch overall length, 3 inches overall height, and 1 1/2 inches overall width, includes a relay, and works with Diablo detectors DSP-40, DSP-50, DSP-55, DSP-13, and AVI-40. The RK1 is designed for mounting and connecting a loop or free exit probe vehicle detector card, and allows hard wiring of the DSD-13 Tri-Axis Detection System to the control box. Both are used in parking access and gate control cabinets.

What are the operating voltage options for Diablo Controls vehicle detectors?

Diablo Controls vehicle detectors are available in several voltage ranges. The DSP-7LP operates on 10 to 30V AC. The DSP-15 LVT and DSP-11 LV operate on 10 to 30V AC/DC. The DSP-20 LV operates on 10 to 30V DC. The DSP-10 117 operates on 117V AC. The DML-9LP lead-in detector operates on 10 to 30V AC/DC. These options allow integration with different control panel power supplies. Always verify the voltage requirement of your specific control system before selecting a detector.

What is the minimum loop inductance required for Diablo Controls detectors?

Most Diablo Controls plug-in vehicle detectors, including the DSP-7LP, DSP-15 LVT, DSP-11 LV, and DSP-10 117, specify a minimum loop inductance of 20 uH. This value indicates the minimum inductance the connected inductive loop must present for reliable detection. The DSP-20 LV does not list a minimum loop inductance in its specifications. When designing or troubleshooting a loop system, ensure the loop meets or exceeds the detector's minimum inductance requirement to maintain proper operation.

What are the physical dimensions of Diablo Controls plug-in detectors?

Diablo Controls plug-in detectors vary in size. The DSP-7LP has an overall height of 1 1/2 inches. The DSP-15 LVT has an overall height of 3 inches. The DSP-11 LV measures 3 inches by 1 1/2 inches. The DSP-20 LV measures 4 inches by 2 inches with an overall height of 2 1/2 inches. The DSP-10 117 has an overall height of 2 1/2 inches. These dimensions are important for panel space planning and ensuring compatibility with existing racks. Always refer to the specific product datasheet for detailed dimensional drawings.

Can Diablo Controls detectors be used in traffic management systems?

Yes, Diablo Controls vehicle detectors are used in parking access, gate control, and traffic management systems to detect vehicle presence. Plug-in models like the DSP-7LP, DSP-15 LVT, DSP-11 LV, DSP-20 LV, and DSP-10 117, as well as lead-in models like the DML-9LP, are designed for inductive loop sensing in these applications. They interface with control systems to signal when a vehicle is present, enabling functions such as gate operation, counting, or access control. Installation should follow the manufacturer's guidelines for loop design and detector configuration.
