CL1XY4-DR1B2 MITSUBISHI

CL1XY4-DR1B2 MITSUBISHI Termination Unit

Product  Description：

The Mitsubishi Termination Unit is a specialized interface component designed for use with Mitsubishi Electric’s programmable logic controllers (PLCs), specifically within the MELSEC series. These units serve as the bridge between field wiring and the PLC’s internal processing modules. By providing a centralized point for signal termination, they simplify the wiring process, reduce the footprint within electrical cabinets, and ensure signal integrity in demanding industrial environments.

Product Parameters

The technical specifications of these units vary depending on the specific model (such as those in the MELSEC-Q or iQ-R Series), but they generally adhere to the following parameters:

• Rated Voltage: Typically supports 24V DC for digital signals, with specific models rated for up to 240V AC for relay outputs.

• Current Rating: Standard terminal blocks usually support 1A to 2A per point, though high-current variants exist.

• Terminal Type: Screw-type terminals or "push-in" spring-loaded terminals for tool-less wiring.

• Connection Density: Available in 16-point, 32-point, and 40-point configurations.

• Mounting Type: Standard 35mm DIN rail mounting.

• Insulation Resistance: Usually rated at 10M Ohm or higher to ensure safety and prevent signal leakage.

• Operating Temperature: Designed for industrial ranges, typically 0 to 55 degrees Celsius.

Product Advantages

Mitsubishi Termination Units are engineered to provide more than just a connection point. Their primary benefits include:

• Space Efficiency: The high-density design allows for a large number of I/O connections in a very narrow width, which is critical for compact control panels.

• Reliability: Built with high-quality materials that resist vibration and thermal expansion, ensuring that connections do not loosen over time.

• Maintenance Speed: Many units feature removable terminal blocks. This allows a technician to replace a faulty module without having to rewire every individual sensor or actuator.

• Error Prevention: Color-coded terminals and clear labeling help installers avoid wiring mistakes during the initial setup.

Precautions for Use

To ensure the longevity of the unit and the safety of the system, several precautions must be observed:

• Wiring Torque: For screw-terminal models, it is vital to apply the manufacturer-specified torque. Over-tightening can strip the threads, while under-tightening leads to arcing and heat buildup.

• Signal Separation: High-voltage AC lines should be routed separately from low-voltage DC signal lines to prevent electromagnetic interference (EMI).

• Environmental Protection: While the units are durable, they should be housed in an enclosure with the appropriate IP rating to protect against conductive dust and moisture.

• Power Down: Always disconnect the power supply before connecting or disconnecting wires to prevent accidental short circuits or damage to the PLC CPU.

Product Applications

These units are ubiquitous in automated industrial sectors where Mitsubishi PLCs are the standard:

• Factory Automation: Used to connect sensors, limit switches, and solenoid valves on assembly lines.

• Automotive Manufacturing: Managing the complex I/O required for robotic welding and paint booths.

• Water Treatment: Terminating signals from flow meters, pressure sensors, and pump controllers.

• Packaging Machinery: Handling the high-speed pulse signals required for counting and sorting applications.
