LC100 – 100m of loop cable LC500 – 500m of loop cable
More commonly used for a free exit or a safety device, the Procon LD100 is an 11 pin detection relay offering pulse or presence relays and can switch between Detect and Un-detect. The detector is connected to an inductive loop inserted in the road surface. When vehicles pass over the loop the detector switches a relay. This output can be used for a number of functions- Free entry Free exit Safety Arming loop for presence for intercoms or swipe systems operated by vehicles to avoid unwanted calls etc…. Count systems Traffic control systems Directional control using the A-B logic
The LD100 or LD102 is the perfect choice for the installer. The advanced features will aid any installation with the LED status lights and the very wide range of sensitivity settings. You also have features such as the ABS, frequency and extended time feature. Easy to set up with a handy 11 pin “din Rail” mount. Installation advice The key factor of any induction loop is the ground condition it is going to be cut into. There are many ways to install induction loops and in many shapes and sizes. There are no set shapes but the basic rectangle is the most common. Installed into the road or pathway, the induction loop should be positioned where it will detect what passes over it at all times. The induction loop works with the principle of magnetic detection from the mass of a moving vehicle and not a pressure pad as sometimes thought. The most common loop installation is to cut a slot in the road to the approximate depth of 50mm x 6mm in a rectangle shape with a feeder slot cut back to the control panel or controller. Once the cables have been laid and pushed down into the slot this should be backfilled with a hot melt road tar or appropriate sealant.
