The SPC-SFMC-X2424C is a harsh-environment programmable controller from Hunan SonnePower International Co., Ltd., designed as a distributed control node for mobile machinery. Its IP67-rated die-cast aluminum housing and -40 to +85°C operating range allow direct chassis mounting without an auxiliary enclosure. A 60-pin AMP connector provides access to 44 total I/O channels — 24 inputs (digital high/low, analog voltage/current/resistance, pulse, and AB quadrature encoder) and 24 outputs (digital high-side and PWM) — all with short-circuit and over-temperature protection on outputs and miswiring protection on inputs. Up to 16 output channels support current feedback for diagnostics.

What communication interfaces are available?

The controller features two independent CAN 2.0B interfaces supporting CANopen and SAE J1939 protocols, enabling both control-level and diagnostic-level networking on the same vehicle bus architecture. One RS232 serial port provides configuration and debugging access, while a dedicated D+ terminal supports vehicle ignition-start detection for automated power-state management. A blue LED status indicator provides at-a-glance operational state verification.

How is the SPC-SFMC-X2424C programmed?

Programming is performed in CoDeSys 3.5 (IEC 61131-3), the industry-standard development environment for mobile machinery automation. This gives control engineers access to all five IEC languages — Ladder Diagram, Structured Text, Function Block Diagram, Instruction List, and Sequential Function Chart — within a single project. In aerial work platform applications, the SPC-SFMC-X2424C has been deployed as the chassis-level controller, coordinating engine start/stop, outrigger deployment, turret rotation, and boom extension via CAN bus communication with the upper-structure controller (SPC-SFMC-X2424A) and a 7-inch display unit (SPD-070-Ax). The controller also supports 4G and BeiDou/GPS dual-mode positioning when integrated with SonnePower's cloud telemetry platform for remote fleet monitoring.
