Product Description

 

Product Description

Order No.: CTH2 231-7HF32
Specification: SM231 8-channel current input, 0-20mA/4-20mA, isolated 16 bit accuracy, with intelligent PID

Product Overview

1. The bus, power supply, and channels are fully isolated, with high reliability and strong anti-interference ability 
2.16 bit sampling accuracy, using hardware filtering technology for more accurate and stable measurement values 
3. The power supply has reverse protection and surge absorption functions, suitable for harsh industrial environments 
4. Integrated with advanced fuzzy logic control algorithms, it does not consume CPU resources and can achieve accurate temperature control without programming, with good dynamic performance 
5. PID control output can be PWM or analog, bipolar output, which can control heating and cooling
