economical temperature controller Feature 1. operation easy, competitive price 2. 3digit display, two alarms 3. TC/ RTD/ Voltage/ Ampere input 4. strong anti-interference ( arrives to 4 KW), adapt to modulate frequency conversion velocity and so on bad industrial environment 5. new algorithm with fuzzy PID control model and parameter 1. How to select type RTD Pt100 TC K(0-600°C) 2. technical parameter Measuring accuracy 1%F.S Control mode ON/ OFF control, PID direction action (cooling), PID reverse control(heating) Control accuracy ±1°C Control output Relay output voltage output Relay contact burden 3A/ 250VAC POWER 90-250VAC 50/60Hz Anti-interference IE6100 CD902 size W96*H96mm CD702 size72*72mm CD402 size W48*H96mm CD102 size W48*H48mm
