MR-J3-D05 MITSUBISHI

MR-J3-D05 MITSUBISHI Central control module

Product  Description：

The MR-J3-D05 is specifically engineered for high-reliability industrial environments. It operates on a $24 \text{ VDC}$ control power supply with a permissible voltage fluctuation of $\pm 10\%$. The unit typically consumes approximately $0.1 \text{ A}$ or less. Its input circuitry is designed for dual-channel safety signals, supporting a response time of $12 \text{ ms}$ or less from the safety input to the output of the servo amplifier’s power stage. The device is compact, with dimensions designed for DIN-rail mounting or direct panel installation to minimize cabinet space. It connects to the servo amplifier via a dedicated safety signal connector and supports the SSCNET III high-speed fiber-optic network communication when integrated into a larger motion control system.

Product Advantages

One of the primary advantages of the MR-J3-D05 is the reduction in hardware complexity. Traditionally, achieving a safety-rated stop required multiple magnetic contactors to disconnect power; this module allows for an electronically controlled "Safe Torque Off" that reduces wear on mechanical components. The use of the module also leads to faster restart times, as the control power to the servo remains active while only the power to the motor is safely cut. Furthermore, its integration with the MR-J3-B series provides superior noise immunity thanks to the fiber-optic communication architecture, ensuring that safety signals are not compromised by electromagnetic interference (EMI) commonly found in industrial plants.

Important Considerations and Precautions

When installing and operating the MR-J3-D05, several safety protocols must be strictly followed. Always ensure that the main power supply is completely discharged before wiring; a wait time of at least 15 minutes after power-off is recommended to avoid residual electric shock. The unit must be installed in a metal control cabinet to meet EMC requirements and protect against environmental contaminants like oil mist or conductive dust. It is critical to perform a safety function test after installation and during periodic maintenance to verify that the STO function correctly disables the motor torque. Users should also ensure that the wiring distance for safety signals is kept within the manufacturer’s specified limits to prevent signal degradation or unexpected latency.

Product Applications

The MR-J3-D05 is widely utilized in industries where human-machine interaction is frequent and safety is paramount. In packaging and food processing, it is used to safely stop machinery when a safety gate is opened or a light curtain is tripped. In automotive assembly lines, it provides the necessary safety category for robotic cells where high-speed motion must be halted instantly for operator access. It is also highly effective in semiconductor manufacturing and textile machinery, where precise motion control must be balanced with strict adherence to global safety certifications. Any application requiring a Category 3 or PL d/SIL 2 safety level on the MELSERVO-J3 platform will typically incorporate this unit.
