Industrial Implementation and Control Scenarios

The MLI-DR32H/D1 is specifically engineered for environments requiring robust electrical isolation and the ability to drive higher current loads directly from the PLC rack.

• Actuator & Solenoid Management: Directly driving 220V AC solenoid valves or motor starters without the need for interposing relays, reducing cabinet space and wiring complexity.

• Safety & Status Indication: Managing large arrays of industrial beacons, sirens, and status indicators across a manufacturing floor.

• Complex Digital Logic: Utilizing the 83ns processing speed to handle high-frequency pulse detection and rapid-fire logic transitions in packaging or material handling systems.

• Global Power Adaptation: Deploying across international facilities due to its flexible 12/24V DC input compatibility, allowing for standardized spare parts inventory.
