Manufacturer: MITSUBISHI
The Mitsubishi AL2-14MR-D is a compact, micro-sized Programmable Logic Controller (PLC) from the Mitsubishi Electric ALPHA 2 (Alpha2) series. It is designed as a cost-effective and simple-to-use automation solution for small-scale applications, replacing traditional relay control panels. This specific model is a unit that integrates a power supply, CPU, digital inputs, and relay outputs into a single, compact device.
Key Features
-
Compact All-in-One Design: Combines the power supply, processor, memory, and I/O in one slim unit, saving panel space.
-
I/O Configuration: 14 I/O Points in total.
-
8 Digital Inputs: 24V DC sinking type.
-
6 Relay Outputs: The “R” in the model number signifies relay outputs, which can switch AC or DC loads.
-
-
Power Supply: 24V DC operating voltage.
-
Programmable: Uses Mitsubishi’s simple ALPHA Programming software, which is based on a ladder logic and function block diagram environment, making it easy for beginners and electricians to learn.
-
Built-in Programming Port: Allows for easy connection to a personal computer for programming and monitoring.
-
Relay Outputs: Can control a wide variety of loads (e.g., contactors, solenoid valves, small motors, indicator lamps) due to the isolation and flexibility of relay contacts.
