MRS Electronic expands Micro PLC CAN family for versatile, networked vehicle control

MRS Electronic has introduced several new additions to its Micro PLC CAN product family, broadening its offering of compact, programmable controllers for on- and off-highway vehicle applications. Designed to either expand existing CAN networks or operate as standalone main controllers, these devices offer a space-saving, cost-effective solution for decentralized vehicle control.

Flexible, compact, and freely programmable

The Micro PLC CAN family now comprises eight models, each tailored for different use cases—from engine fan control and light management to pressure monitoring in support systems. All controllers are freely configurable and programmable, making them suitable for custom applications in tight installation spaces where traditional large-scale PLCs are impractical or over-featured.

Key use cases include:

• Engine compartment fan control
• Light control with multiple operating modes
• Ground pressure monitoring on vehicle supports

CAN-enabled small controllers with targeted features

All Micro PLC CAN products provide CAN bus connectivity and are programmed using MRS Applics Studio, a visual programming interface designed to simplify development. A basic understanding of digital logic is enough to start creating automation logic without needing advanced programming skills.

Here’s a breakdown of key models:

• Micro PLC CAN Relay 32-bit: Combines the 12 V and 24 V variants into one pin-compatible unit with expanded computing power and voltage range (9–32 V), plus a NO 10 A / NC 5 A relay output.
• Micro PLC CAN 12 V / 24 V: Differ only in voltage; offer up to two analog inputs, one analog input + one digital output, and two overload-protected high-side power outputs or relay outputs.
• Micro PLC CAN 9–30 V: Offers additional flexibility with two PWM-capable outputs and a broader voltage range.
• Micro PLC CAN 4 I/O: All four channels are freely configurable as analog or digital inputs/outputs, including PWM. Includes an additional analog input and full CAN bus compatibility.
• Micro PLC CAN 4 ANA: Features four configurable analog I/Os (0–24 mA or 0–10 V), with optional frequency input functionality.

DTM connector variants for rugged environments

MRS also offers DTM versions of the Micro PLC CAN and 4 ANA units, featuring DEUTSCH DTM connectors and reinforced thermoplastic housings. These are built for high-resistance against moisture, vibration, and temperature fluctuations, making them ideal for agricultural and construction applications. DTM connectors are also available for other MRS modules upon request.
