In asphalt paving, the grade and slope control module is the electronic core of the paver's automatic leveling system. It receives input from grade sensors and slope sensors mounted on the screed, then outputs control signals to the screed lift cylinders to maintain the target paving thickness and cross-slope angle. The S276M 04-21-40110 module replaces the original leveling control unit on asphalt pavers, processing sensor signals with shielded circuit design suited to the electromagnetic interference present on construction sites. The module is supplied as a new unit built to OEM specifications, with connector layout matching the original wiring harness for direct installation.
The module processes signals from the paver's grade sensor to maintain the target screed height relative to the reference surface. By continuously adjusting the screed lift cylinder output, the module helps keep paving thickness within the target range, reducing mat thickness variation that can lead to premature road surface failure.
The slope control function receives input from the screed-mounted slope sensor and adjusts the relative height of the left and right screed sides to maintain the specified cross-slope percentage. This function supports road drainage design requirements by ensuring the paved surface follows the intended slope profile.
The module's internal circuitry is designed with signal shielding to reduce the impact of electromagnetic interference from nearby paver engines, heating elements, and construction-site equipment. This shielding helps maintain stable sensor signal processing during continuous paving operations, where electrical noise from adjacent systems can affect unshielded control units.
The S276M 04-21-40110 module is manufactured to match the original equipment's connector pin configuration, mounting dimensions, and signal processing parameters. This allows maintenance technicians to install the module by connecting it to the existing wiring harness without soldering, adapter plates, or wiring modifications.

The S276M 04-21-40110 grade and slope control module is designed for installation on asphalt pavers equipped with an automatic leveling system using the original 04-21-40110 control unit. Before installation, maintenance personnel should verify that the paver's existing wiring harness connector matches the module's connector configuration and that the grade and slope sensors are functioning within normal ranges. The module is installed by connecting it to the original wiring harness and securing it in the factory mounting location. No wiring modifications, calibration equipment, or software setup are required for a standard replacement. After installation, the module is ready to operate with the paver's existing grade and slope sensors. For buyers unsure whether their paver model uses the 04-21-40110 module, JESTIN recommends providing the paver brand, model, and serial number to confirm compatibility before purchase.
Each S276M 04-21-40110 module is tested before shipment to verify powered-on status, sensor signal input recognition, and control output response. The modules are inspected for connector pin integrity and housing condition to ensure they arrive ready for installation. JESTIN provides a 6-month warranty covering manufacturing defects in materials and workmanship under normal operating conditions. For industrial clients and commercial users maintaining paver fleets, the module offers a cost-effective replacement option that matches OEM specifications for signal processing and connector compatibility. Standard orders ship from Shanghai Port within 7-15 working days of payment confirmation. Payment is accepted via TT, LC, and Western Union.
The 04-21-40110 module is specified as a replacement for asphalt pavers that use the original 04-21-40110 grade and slope control unit. Compatibility depends on the paver's wiring harness and leveling system configuration. Buyers should contact JESTIN with their paver brand, model, and serial number to verify fitment before ordering.
The 04-21-40110 module is designed as a direct replacement matching original signal processing parameters. Once connected to the existing wiring harness and functional grade and slope sensors, it operates without additional calibration equipment or software setup. If the paver's existing sensors are out of calibration, those sensors should be adjusted according to the paver manufacturer's procedure.
The warranty covers manufacturing defects in materials and workmanship, including circuit board failure, connector defects, and signal processing malfunction under normal operating conditions. Damage from improper installation, water immersion beyond design limits, unauthorized modification, or connection to incompatible voltage systems is not covered.
The S276M 04-21-40110 module is designed and specified for asphalt paver grade and slope control systems. It is not intended for use with CNC machinery, land-leveling tractors, or other equipment types. Using the module outside its specified application may result in incompatible signal processing and is not covered by the warranty.
For industrial clients and road contractors seeking a reliable grade and slope control module replacement for asphalt pavers, the S276M 04-21-40110 unit offers OEM-spec compatibility, anti-interference circuit design, and a 6-month warranty. Contact JESTIN with your paver model details to confirm compatibility and request a quotation.
