The IT6500 has a DB25 analog control interface on the back panel, which allows the user to control the front panel output voltage or current value from 0 - 100% of full scale through 0 – 10 V or 0 – 5 V analog. In addition, the user can also control the output value through 0 – 10 K or 0 – 5 K resistors. The analog control interface meets the control requirements in industrial production and allows the customer to control the output voltage through a PLC without the need to use PC control.
