Sernis lights the way with road studs for harsh conditions

Portuguese manufacturer Sernis has introduced the SR-40, a reflective road stud that is very much at home in harsh conditions and is snowplough-resistant. Its design includes a solar panel of less than 1W in power, making it perfect for countries with low sun exposure. The stud also has RF low power 868MHz mesh network communication and has microcontroller technology inside each stud. Features include a wake up and sleep function, automatic brightness control and night-level contraction.

Portuguese manufacturer 7640 Sernis has introduced the SR-40, a reflective road stud that is very much at home in harsh conditions and is snowplough-resistant. Its design includes a solar panel of less than 1W in power, making it perfect for countries with low sun exposure.

The stud also has RF low power 868MHz mesh network communication and has microcontroller technology inside each stud. Features include a wake up and sleep function, automatic brightness control and night-level contraction.

The stainless steel, aluminium and polycarbonate body house two uni-directional LEDs and four bi-directional LEDS.

To complement the SR-40, Sernis has produced another snow-plough resistant stud, the inductive power SR-45 IPW. Installation is easier through the plug-and-light concept. A non-wired connection prevents unnecessary drill and deterioration of the road in future interventions. And all road studs are connected to the Control Central Unit to allow several control features.

The 3kg SR-45 IPW uses 230 volts AC and its 8 LEDs consume 5 Watts of power. Sernis says it is suitable for use in roads, tunnels, parks and airports.

The 3112 is an isolated AC voltage to DC voltage module while the 3114 is an isolated AC current to DC voltage module. Both devices can convert up to 400V AC or 5A AC signals to 0~5V DC signals for data acquisition cards to measure while reducing the harmful effects of ground loops, field noise and electrical interference.These modules are suitable for DIN rail mounting, designed for
