Power Input 90-264VAC 50/60 HZ

Future Design’s 2500 series breaks all the rules for 32nd DIN controllers. Input sample rate of 5 scans per second, current transformer (heater break monitoring) or second analog input (remote setpoint or event input) is included as standard on the 2500. 18 bit A/D and 15 bit D/A offer the highest accuracy for industrial control applications. The 2500 can be supplied with up to 2 control outputs, alarm and communications (or analog retransmission), all in a 32nd DIN package.

The 2500 can also be equipped with a 20VDC/25mA power supply if output 2/alarm 2 is not required. Standard software functionality includes Fuzzy logic + PID, Ramp/Soak, timer function, pump control, dual setpoint (event selectable) and more. With isolated inputs/outputs, UL/CSA and CE, the 2500 can go anywhere and do the job
