⚡ Synergy Logic SLM-RP4: Raspberry Pi 4 PLC

Synergy Logic has introduced the SLM-RP4, an industrial programmable logic controller built around the Raspberry Pi 4 Model B. Designed for automation, machine control, and Industrial IoT applications, this DIN-rail mountable unit integrates modular I/O capabilities via a dedicated backplane.

The controller features an SPI-based backplane that supports up to eight Synergy Logic I/O modules, enabling a total of 128 I/O points. It operates on a 24V DC input and is housed in a fanless aluminum enclosure suitable for harsh environments. Connectivity options include Gigabit Ethernet, dual-band WiFi 5, Bluetooth 5.0, and multiple USB ports for peripheral expansion.

Video output is provided through two micro-HDMI ports, while audio is handled by a 3.5mm jack. The system includes a 16GB microSD card for storage and runs Raspberry Pi OS with OpenPLC pre-installed. This setup allows users to program standard IEC 61131-3 logic directly on the device, leveraging the familiar Raspberry Pi ecosystem for industrial tasks.
