GT1572-VNBA MITSUBISHI Digital Input Module

Product  Description：

The Mitsubishi Digital Input Module is a high-performance component within the MELSEC series (primarily the iQ-R, iQ-F, and Q Series) designed to bridge the gap between field sensors and the programmable logic controller (PLC). These modules receive discrete signals—such as ON/OFF, open/closed, or high/low—from devices like pushbuttons, limit switches, and proximity sensors, converting them into digital logic for the PLC processor.

Product Parameters

The specifications of these modules vary depending on the specific series, but they generally follow these technical standards:

• Input Type: Available in DC input (typically 24V DC), AC input (100-240V AC), and dry contact (source/sink) configurations.

• Number of Points: Common configurations include 16, 32, or 64 points per module to accommodate different system scales.

• Rated Input Voltage: Most industrial models operate at 24V DC with a permissible range of 19.2V to 28.8V.

• Input Current: Typically ranges from 4mA to 7mA per point depending on the module model.

• Response Time: Features adjustable filter times to prevent "chattering," usually ranging from 0.1ms to 70ms.

• Isolation Method: Utilizes photocoupler isolation to protect internal PLC circuitry from external electrical surges.

• Connection Type: Offered in terminal block styles, 40-pin connectors, or MIL connectors for high-density wiring.

Product Advantages

Mitsubishi digital input modules are recognized for their industrial-grade reliability and seamless integration within the MELSEC ecosystem.

• High-Speed Processing: They offer ultra-fast response times, which are essential for high-speed production lines and precise synchronization.

• Compact Design: High-density 64-point modules allow for significant space savings within the control cabinet.

• Enhanced Diagnostics: Many models include LED status indicators for every input point, allowing technicians to troubleshoot field wiring issues at a glance.

• Durability: Built to withstand harsh industrial environments, including high temperatures and mechanical vibrations.

• Flexible Wiring: Support for both sink and source wiring allows the same module to be used with various global sensor standards.

Important Considerations and Precautions

To ensure long-term stability and prevent hardware damage, several precautions must be followed during installation and operation.

• Wiring Polarity: Ensure that the common (COM) terminal is correctly wired according to whether you are using sink or source logic; incorrect wiring can prevent signal detection or damage the module.

• Voltage Levels: Never apply AC voltage to a DC input module. Always verify the rated voltage on the module casing before powering the system.

• Noise Mitigation: Keep input signal wires away from high-voltage power cables or motor drive leads to prevent electromagnetic interference from causing false triggers.

• Heat Dissipation: When using high-density modules where all points are frequently ON, ensure the control cabinet has adequate ventilation to prevent overheating.

• Hot Swapping: Most Mitsubishi modules should not be removed or inserted while the PLC base unit is powered on unless the specific backplane supports online module replacement.

Product Applications

These modules serve as the "sensory system" for automated machinery across various sectors.

• Factory Automation: Detecting the presence of parts on a conveyor belt via proximity sensors or photocells.

• Machine Tools: Monitoring the status of safety doors, emergency stop buttons, and limit switches on CNC machines.

• Packaging Industry: Managing high-speed trigger signals for labeling, sorting, and wrapping processes.

• Automotive Assembly: Coordinating robotic cell inputs to ensure parts are correctly positioned before welding or assembly begins.

• Material Handling: Tracking the position of elevators, automated guided vehicles (AGVs), and warehouse cranes.
