RevPi DO 16O Digital Output Module for PLC, 12-24V DC

Overview of the RevPi DO 16O Digital Output Module

The RevPi DO 16O is a high‑performance digital output module designed for integration with PLC systems and industrial automation platforms. It delivers up to sixteen independent, isolated outputs that can be driven by standard 12 V to 24 V DC signals, making it ideal for controlling relays, actuators, indicators, and other low‑power devices in a wide range of applications.

Key Features

• 16 Independent Channels: Each channel operates independently, allowing simultaneous control of multiple devices without cross‑talk or interference.
• Wide Voltage Range: Supports input voltages from 12 V to 24 V DC, providing flexibility for different PLC and automation system requirements.
• Electrical Isolation: Each output is isolated from the module’s internal circuitry, protecting sensitive equipment and ensuring safety in hazardous environments.
• Compact Form Factor: Designed to fit seamlessly into standard RevPi Core/Core 3/Connect chassis or other compatible expansion boards.
• Robust Construction: Built with industrial‑grade components that withstand temperature variations, vibration, and electrical noise common in factory settings.
• Easy Integration: Features standard JST-PH connectors for straightforward wiring to PLC outputs or other control devices.
• Software Compatibility: Works with RevPi’s open‑source software stack, including the Python, Node‑RED, and PLC‑style programming environments.

Technical Specifications

Applications

The versatility of the RevPi DO 16O makes it suitable for a broad spectrum of industrial and research scenarios:

• Factory Automation: Control conveyor belts, robotic grippers, or safety interlocks.
• Process Control: Operate valves, pumps, or temperature sensors in chemical or food processing lines.
• Building Management: Manage HVAC systems, lighting controls, and access control devices.
• Laboratory Equipment: Interface with test rigs, data acquisition systems, or custom instrumentation.
• Energy Management: Switch renewable energy inverters, battery chargers, or smart grid components.

Integration Workflow

Integrating the RevPi DO 16O into an existing PLC setup involves several straightforward steps:

1. Mounting: Insert the module into a compatible RevPi expansion slot or attach it to a custom PCB using standard mounting hardware.
2. Cabling: Connect each output channel to the desired actuator or relay using JST-PH cables. Ensure proper polarity and secure connections.
3. Configuration: Use RevPi’s web interface or command‑line tools to assign logical addresses to each channel, set voltage thresholds, and enable safety features.
4. Programming: Write control logic in the chosen environment (Python, PLC ladder logic, etc.) to toggle outputs based on sensor inputs or process conditions.
5. Testing: Verify that each output responds correctly to software commands and that isolation integrity is maintained under load.

Software Support

The module’s firmware exposes a simple API that can be accessed via:

• RESTful HTTP endpoints for quick integration with web‑based dashboards.
• Python libraries (e.g., revpi.io) for scripting and automation tasks.
• Standard PLC ladder logic modules that map directly to the 16 output channels.

Safety Considerations

When deploying the RevPi DO 16O, adhere to the following safety guidelines:

• Always verify that the input voltage does not exceed 24 V DC to prevent damage.
• Use proper grounding techniques to avoid electric shock hazards.
• Ensure that the load current per channel remains within specified limits (typically <30 mA).
• Implement fail‑safe logic in software so that outputs default to a safe state during communication loss or power failure.

Conclusion

The RevPi DO 16O Digital Output Module offers a reliable, scalable solution for controlling up to sixteen discrete devices within industrial automation and research environments. Its wide voltage compatibility, electrical isolation, and seamless integration with RevPi’s open‑source ecosystem make it an attractive choice for engineers seeking flexibility without compromising on performance or safety.
