Ultra thin temperature controller - 22.5mm width


New temperature controller in D5 module (with communication) 

Now we re-design the circuit to put the conventional temperature controller into this green tiny rail mounted unit - D5 module.
Rail mounted 22.5mm thin
Apart from the exiting model: AI-7048-D5, AI-7028-D5, AI-3011-D5 and AI-3013-D5, we launched AI-516-D5, AI-516P-D5, AI-519-D5, AI-526-D5 and also AI-526P-D5.

DC Analog Signal Generator

Yudian Indicator AI-501 V7.61
Yudian DC Analog Signal Generator 4-20mA, 0-20mA
 4-20mA DC Signal Generator feature is added to AI-501 V7.61. User can output any DC signal 0-20mA, 4-20mA, 0-5V, 0-10V, 0-20V signal just by having one unit of AI-501-D2-X3-Q V7.61.



Yudian temperature controller series, AI-5 series will introduce a new UL line. Those which complies with UL IEC 61010-1:2010 will be added by suffix -UL. The best selling series AI-509-D2 in black color will be become AI-509-D2-UL-Q.
AI-208 provides standard digital PID temperature control features, including high alarm, low alarm, high deviation alarm, low deviation alarm, thermocouples or Pt100 input, SSR or relay output. The setpoint limitation protects equipment and safety measures for end users.
