BERGHOF RDC2 Centrotherm 500K Dedicated Servo Motion Controller

RDC2-Centrotherm 500K is a customized motion control PLC developed by BERGHOF Automation Germany exclusively for Centrotherm thermal processing equipment. Programmed under CODESYS environment, it integrates multi-axis servo control, analog temperature sampling and digital logic processing in one compact DIN-rail unit. It serves as the core master controller for diffusion furnaces, coating and solar cell thermal production lines, realizing closed-loop motion and precise temperature regulation simultaneously.

Equipped with multiple DB9 serial communication ports, pluggable spring-cage I/O terminal blocks and dedicated servo expansion slots, this controller supports direct connection to servo drives, PT100 temperature transmitters and limit switches. It features robust anti-vibration industrial casing, wide-range DC power input and built-in short-circuit protection, widely used as replacement spare parts for aging Centrotherm photovoltaic thermal equipment production lines worldwide.
