Product Description

The RD78G4 motion controller, part of the Melsec RD78G4 module series, is designed for high-precision industrial automation with 32 digital inputs and 32 digital outputs. It supports direct integration of up to 16 servo amplifiers via built-in SSCNET III/H communication, enabling seamless control of High-speed RD78G4 servo systems. Operating within a 24 VDC ±10% voltage range and a temperature tolerance of -10°C to +55°C, this controller ensures reliability in harsh environments. Compatible with EtherCAT, CC-Link IE Field, and PROFINET interfaces, it excels in automotive, robotics, and packaging industries. Key advantages include ultra-fast cycle times (62.5 µs) for real-time synchronization and compact modular design, though its complexity may require specialized programming expertise. Battery capacity for memory backup is 190 mAh, while screen compatibility extends to standard HMI displays for system monitoring. Detection range for positional accuracy reaches ±1 pulse, ideal for high-speed motion applications demanding precision and repeatability.
