L4C3
Overview

Overview of the L4C3

Indication Instruments offers the L4C3 Instrument Cluster , a modern vehicle dashboard solution designed for commercial vehicles, agricultural machinery, construction equipment, mining vehicles, and off-highway applications. The L4C3 combines four high-precision Sonceboz stepper motor gauges with a vibrant 5-inch TFT display , delivering the perfect balance of traditional analogue instrumentation and advanced digital visualization. Featuring CAN Bus 2.0B (J1939) communication , multiple analog and digital inputs, integrated audio alerts, and software upgrade capability, the L4C3 provides reliable vehicle monitoring, diagnostics, and operator information in demanding working environments. The L4C3 Instrument Cluster is engineered to provide operators with accurate, real-time vehicle information through a combination of precision analogue gauges and a high-resolution TFT display. The four Sonceboz stepper motor-driven gauges offer smooth and reliable measurement of critical vehicle parameters, while the 5-inch TFT display presents operating data, warning messages, diagnostics, and system information in a clear graphical format. Designed for modern commercial and off-highway vehicles, the cluster supports CAN Bus 2.0B (J1939) communication, enabling seamless integration with electronic control systems while delivering dependable performance in harsh operating conditions.
