JRMSI-B1034 YASKAWA Termination Unit

Product  Description：

Yaskawa Termination Units are specialized interface components designed to facilitate the organized and secure connection between field wiring and the I/O modules of a machine controller or drive system. These units act as a centralized wiring hub, converting high-density module connectors (such as 40-pin or 50-pin connectors) into accessible screw or spring-clamp terminals. This physical transition is essential for maintaining signal integrity, simplifying maintenance, and ensuring that field sensors and actuators are correctly integrated into the control architecture.

Product Parameters

The technical profile of a Yaskawa Termination Unit is defined by its electrical capacity and physical connection density:

• Terminal Density: Available in various configurations, commonly supporting 16-point, 32-point, or 50-point terminal blocks to match the associated I/O module.

• Rated Voltage: Designed to handle standard industrial control voltages, typically rated up to 125V AC or 30V DC depending on the specific model.

• Rated Current: Generally supports a continuous current of 1A to 2A per terminal, with higher ratings available for power distribution blocks.

• Insulation Resistance: High-level dielectric strength, typically rated at 500M ohms or higher at 500V DC to prevent cross-channel leakage.

• Wire Compatibility: Supports a wide range of wire gauges, usually from 22 AWG to 14 AWG, accommodating both solid and stranded copper wires.

• Mounting Method: Standard 35mm DIN rail mounting for quick installation and removal within industrial control cabinets.

Product Advantages

Utilizing Yaskawa Termination Units offers several strategic benefits for system integrators and maintenance teams:

• Simplified Wiring and Maintenance: By using pre-assembled cables to link the controller to the termination unit, users eliminate the need for tedious point-to-point wiring at the PLC rack, which significantly reduces the risk of wiring errors.

• Enhanced System Reliability: The use of high-quality terminal blocks ensures a vibration-resistant connection, which is critical for machines operating in high-movement environments like robotics or stamping presses.

• Easy Troubleshooting: Every terminal is clearly labeled with numbering that corresponds to the PLC’s internal address, allowing technicians to quickly probe signals with a multimeter without dismantling the controller.

• Space Optimization: The compact vertical or horizontal design allows for high-density wiring in a small footprint, freeing up valuable space on the control panel's backplane.

• Flexible Termination Options: Available in both traditional screw-type terminals for heavy-duty connections and push-in spring terminals for rapid, tool-less assembly.

Product Applications

These units are foundational components in any distributed or centralized control system:

• Servo Drive Integration: Centralizing the feedback and control signals from multiple Sigma series servomotors to a single controller rack.

• Robotic Control Cabinets: Managing the high volume of I/O signals required for robotic end-effectors, safety interlocks, and sensor arrays.

• Material Handling Systems: Serving as the junction point for long-distance wiring from conveyor sensors and motor starters back to the main MP series controller.

• Precision Assembly Machinery: Organizing the delicate analog and digital signals used in semiconductor bonding or electronic component placement.

• Remote I/O Stations: Acting as the primary wiring interface for distributed I/O blocks located far from the main CPU, connected via fieldbus networks.

Important Precautions

To ensure the safety of the electrical system and the longevity of the hardware, the following precautions are essential:

• Tightening Torque: For screw-terminal versions, always use the manufacturer-specified torque (typically 0.5 to 0.8 Nm). Over-tightening can strip the threads, while under-tightening leads to high-resistance connections and potential fire hazards.

• Cable Length Limits: While termination units allow for organized wiring, ensure the total cable length between the controller and the field device does not exceed the maximum specification for the signal type to avoid voltage drops or signal interference.

• Common Line Capacity: Pay close attention to the common (COM) terminals. Ensure that the total current returning through a single common terminal does not exceed the unit’s maximum rated capacity.

• Proper Shielding: When terminating shielded cables for analog signals or high-speed encoders, ensure the shield is correctly terminated to the ground bar or designated shield terminal to prevent electromagnetic interference.

• Environment Protection: Ensure the termination unit is installed in an enclosure that provides adequate protection against conductive dust, oil mist, and moisture, which can cause short circuits across adjacent terminals.
