The NEO2B is a simplified, robust blower control panel manufactured by AURORA Konrad G. Schulz GmbH & Co. KG for off-highway vehicle operator cabins. It replaces complex HVAC interface panels with an intuitive two-knob layout — one for temperature, one for three-speed blower selection (Low/Medium/High) — plus up to two rocker switches for air conditioning compressor engagement and cabin air recirculation control. The panel is designed for heavy-duty operator environments where tactile controls and mechanical durability take priority over touchscreen sophistication.

What electrical interface does the NEO2B use?

The panel operates on 12V DC vehicle power and requires an ignition input (+12V DC) to enable operation. A 15-second hysteresis period after power-up prevents unintended mode changes during system stabilization. The blower output supports Low, Medium, and High speed selection via dedicated terminals, with a maximum blower output rating of 25 A. Auxiliary outputs for the A/C compressor clutch and coolant pump are rated at 5 A each.

What environmental conditions does the NEO2B withstand?

The front panel carries an IP54 protection rating against dust ingress and water spray from any direction, while the internal electronics are rated for continuous operation from -40 to +85°C — matching the full off-highway temperature envelope encountered by construction, agricultural, and mining machinery. The simplified mechanical interface with rotary knobs and rocker switches eliminates failure-prone touchscreens and membrane keypads, ensuring reliable cabin climate control under vibration, shock, and contamination exposure.
