Product Description:

Sanyo Denki is a Japanese manufacturer known for its reliable motion control products. It specializes in servo systems, power systems and cooling fans. With decades of experience, the company provides products widely used in automation, robotics and precision equipment industries.

The RBD2A-204 Servo Amplifier is a compact unit designed for efficient motor control. It operates with a dual voltage input system. This dual voltage design ensures that both power and control systems are managed independently. This contributes to operational safety and stability. The main power supply requires DC 24 V at 2 A while the control circuitry operates on DC 5 V at 0.2 A. This setup ensures stable operation and control accuracy. This device features four connector interfaces. CN1 is a 5 pin Molex type for power and control signals that supports POW and ALM indicators. CN2 and CN3 are both 6 pin JST-type connectors for signal input and encoder feedback. CN4 is a 36 pin D-sub connector that is used for motor control and extensive I/O interfacing. These connectors enable smooth integration into various industrial applications. LED indicators include POW for power status and ALM for fault monitoring. This unit also includes a 6 position DIP switch on the side. These switches are used for mode setting, device ID selection, or parameter configuration. This allows fast on site adjustments.

The RBD2A-204 Servo Amplifier is optimized for DIN or panel mounting. Its slim design fits compact enclosures without space concerns. The unit's steel casing includes venting for heat dissipation. This model has a width of approximately 1.5 inches or 38 mm. This slim form factor makes this BL super series servo amplifier suitable for tight installation spaces.
