SC402-012-T3 by Pacific Scientific

The Pacific Scientific SC402-012-T3 servo controller is a precision device within the SC400 Servo Drives series, manufactured by Pacific Scientific for demanding industrial automation tasks. Featuring a robust 24 VDC input voltage and a rated output current of 12 A, this controller delivers efficient power management with a compact 150 x 100 x 40 mm profile. Its primary function is digital closed-loop control of brushless servomotors, providing PID-based torque and velocity regulation in applications where accuracy and repeatability are essential.

Equipped with dual communication interfaces—RS-485 and CANopen—the SC402-012-T3 supports seamless integration into modern control networks. The device’s high-resolution encoder inputs facilitate precise position and speed feedback, while its multiple control modes include four-quadrant torque and velocity control with adjustable acceleration/deceleration parameters. Housed in a panel or DIN-rail mountable enclosure, this controller operates over an ambient temperature range of –10 °C to +50 °C and weighs just 3 kg. An optically and magnetically isolated output stage ensures signal integrity under challenging conditions, and its brushless design eliminates maintenance points for long-term reliability.

Additional protective features safeguard the SC402-012-T3 against under- and overvoltage, overcurrent, short-circuit events, and thermal overload, conforming to stringent industrial safety standards. The device requires no external transformer and supports motors with frame sizes of 3.25 in or 4.25 in, making it compatible with a wide range of Pacific Scientific servomotors. Its space-saving design and efficient PWM output enable lower heat generation and reduced energy consumption. By combining high performance, comprehensive protection, and flexible mounting options, the SC402-012-T3 enhances system uptime and productivity, delivering reliable motion control solutions for advanced industrial automation applications.
