CH Series Cost-Effective Universal Input Temperature Controllers

Product Introduction

The CH Series Temperature Controllers are compact and economical instruments designed for reliable temperature regulation across a wide range of industrial and commercial applications. Featuring a universal input that supports both thermocouples and RTD sensors, the CH Series combines stable performance with a short-depth housing, making it ideal for space-constrained installations. Its cost-effective design, simple operation, and dependable control functions make it a popular choice for general-purpose temperature control tasks.

FAQ

Q1: What is the main difference between CH Series and REX-C Series?
A1: Both share similar functions, but CH Series uses a switching power supply (short body, ~80 mm), while REX-C uses transformer-based long body (~110 mm).

Q2: Can CH Series support PID control?
A2: Yes, CH Series supports PID control with auto-tuning in addition to simple On/Off mode.

Q3: Does CH Series support multiple sensor types?
A3: Yes, it supports universal input for thermocouples and RTD sensors.

Q4: Is CH Series suitable for high-precision control?
A4: It is reliable for general applications; for higher accuracy and advanced communication, we recommend TC or TC5 Series.
