SV100-4T-0300L MITSUBISHI Digital Input Module

Product  Description：

Mitsubishi Electric Digital Input Modules are specialized interface components designed to detect and process discrete signals from field devices. These modules act as the sensory input for a Programmable Logic Controller (PLC) system, converting external electrical signals—such as those from push buttons, limit switches, and proximity sensors—into digital data that the CPU can interpret. They are a staple of the MELSEC series, known for their high-speed response and electrical isolation.

Product Parameters

The technical profile of a Mitsubishi Digital Input Module is defined by its electrical compatibility and signal density:

• Input Points: Available in high-density configurations including 16-point, 32-point, and 64-point versions to maximize rack space.

• Rated Input Voltage: Standard models operate at 24V DC, while specialized versions are available for 100V-120V AC and 200V-240V AC applications.

• Input Current: Typically rated at approximately 4mA to 6mA per point to ensure reliable detection while minimizing power consumption.

• ON/OFF Voltage Thresholds: For a 24V DC module, the "ON" voltage is generally 19V or higher, while the "OFF" voltage is 11V or lower.

• Response Time: Features adjustable hardware and software filters, with response times as low as 0.1ms for high-speed detection requirements.

• Insulation Method: Utilizes photocoupler isolation between the input terminals and the internal PLC logic for maximum protection.

Product Advantages

Mitsubishi Digital Input Modules offer several engineering benefits for industrial environments:

• High-Speed Processing: Designed to keep pace with modern high-speed production lines, ensuring that no signal pulse is missed during rapid machine cycles.

• Selectable Wiring Logic: Most DC modules support both "Sink" and "Source" wiring configurations, providing flexibility for different global wiring standards.

• Intelligent Noise Filtering: Built-in digital filters allow users to customize the debounce time, preventing false triggers caused by electrical noise or mechanical vibration.

• Space-Saving Design: The 64-point modules utilize high-density connectors (such as 40-pin headers), allowing for massive I/O counts within a very small control panel footprint.

• Visual Diagnostics: Each input point is paired with a dedicated LED indicator on the front panel, enabling maintenance staff to verify sensor status without a computer.

Product Applications

These modules are the primary interface for various discrete sensing tasks:

• Machine Safety: Monitoring the status of E-stop buttons, safety gates, and light curtains to ensure operator protection.

• Position Sensing: Receiving signals from inductive proximity sensors and limit switches to track the movement of pneumatic cylinders or conveyor belts.

• User Interface: Processing commands from operator control panels, including start/stop buttons and selector switches.

• Process Monitoring: Detecting binary states from pressure switches, level floats, and flow switches in fluid management systems.

• Packaging Lines: Tracking product presence and counting items as they pass through high-speed sorting and boxing machinery.

Important Precautions

To ensure long-term reliability and prevent electrical damage, users should observe the following:

• Common Terminal Current: Ensure that the total current flowing through the "Common" (COM) terminal does not exceed the module's rated limit, especially in high-density modules.

• Wiring Separation: Route input signal wires in separate conduits or trays away from high-voltage motor cables to prevent electromagnetic interference from causing "ghost" signals.

• Voltage Regulation: Use a stabilized 24V DC power supply. Excessive ripple or voltage spikes can damage the photocouplers or lead to inconsistent signal detection.

• Connector Integrity: For modules using 40-pin connectors, ensure the connector is fully seated and locked. Use a dedicated crimping tool for the pins to prevent loose connections.

• External Circuit Protection: When using AC input modules, ensure the circuit is fused appropriately to protect the module internal circuitry from external short circuits.
