Custom Control Panels

Temperature PID Controller - FY400-12V-DC

12 VDC PID Controllers

DIN 1/16

12 Volt PID Controller
RoHS Compliant


Temperature PID Controller - FY400 - 12 Volt - DC
Proportional Integral Derivative Controllers

*Now With BRIGHTER LED's For Daylight Conditions


A field proven Proportional Integral Derivative Controller that handles some of the toughest environments in the World. The use of the latest technology in design, components and manufacturing gives excellent performance and unit stability, while double-sided surface mount technology results in comprehensive functionality at a low price.

12 Volt - DC - Heavy Duty Process and Temperature PID Controller that offers excellent value for money.

We have developed the FY 400-12VDC (DIN 1/16) and the FY 900-12VDC (DIN 1/4) temperature controllers with a 12V DC power supply with brighter LEDs for outside daylight use. These controllers are commonly used outdoors where only a 12V DC battery is available and they operate mainly in outdoor daylight conditions. Both models are IP 65 rated with fully enclosed casings.
