The M-Duino 38R+ PLC from Industrial Shields is an industrial programmable logic controller featuring 38 total input and output points, including eight relay outputs. Built around the Arduino Mega 2560 platform, this controller combines analog/digital I/O, isolated digital connections, relay switching, and multiple industrial communication interfaces.
Available through AIWTS, the M-Duino 38R+ is suitable for automation projects requiring both signal monitoring and relay-based control.
The M-Duino 38R+ provides 19 inputs and 19 outputs across its industrial I/O configuration.
Its specifications include:
The relay outputs provide switching capabilities for compatible electrical loads.
According to the manufacturer, relay ratings for resistive loads include 230 VAC at a maximum of 4 A and 24 VDC at a maximum of 2 A.
Applications involving inductive loads require additional consideration. Industrial Shields recommends appropriate RC snubber protection based on the characteristics of the connected load.
The M-Duino 38R+ uses the ATmega2560 microcontroller and supports development through the Arduino IDE with Industrial Shields board packages.
Controller specifications include:
This platform provides engineers with an Arduino-based development environment for creating and maintaining industrial control applications.
The M-Duino 38R+ PLC includes multiple communication interfaces for connecting compatible industrial devices.
Available interfaces include:
These communication features support connected monitoring and control systems where multiple interface types are required.
The M-Duino 38R+ operates using a 12–24 VDC power supply and supports ambient operating temperatures between 0°C and 60°C.
Physical specifications include:
The power consumption figure was measured at 24 VDC with all outputs active and no external load. Actual power requirements depend on operating conditions and connected equipment.
The controller must be installed in an appropriate protective enclosure or electrical cabinet according to the manufacturer’s installation instructions.
