CT435PD

The Minco CT435PD is a versatile temperature controller designed for precise temperature management. It supports two RTD inputs, compatible with PT100 or PT1000 sensors, and covers a wide temperature sensing range from -70°C to 650°C.

This controller features two independent solid-state open-drain outputs, each capable of handling up to 5A. Each output can be individually configured for PID, on/off, or alarm control, providing flexibility for various applications. The device incorporates automatic tuning to estimate PID coefficients for multiple control types.

Configuration and control are managed via a Modbus over UART interface, allowing multiple units to be connected on a single UART line. It operates from a 5V power supply and is designed in a small package for direct PCB mounting, requiring no additional heatsinking. The 32-bit microprocessor executes two PID loops simultaneously at a configurable rate up to 25 times per second.

Key specifications include 2 inputs, 2 switched outputs, and Limit/PID control technology. The CT435PD is suitable for applications requiring accurate temperature monitoring and control in a compact, low-cost solution.
