4.12 External Analog Quantity Function (Option)

IT-M7700 series power supply provides a optional DB25 analog interface(IT-
E1208). The analog interface provides the following capability:

4.12.1 Definition of Analog Interface

Analog signal bandwidth is less than 100 Hz, supports any waveform within sig-
nal bandwidth. When the program signal frequency or amplitude exceeds output
capacity, the output amplitude will be automatically limited. The definitions and
descriptions for analog interface are as follows. The accuracy of the analog
function (input or output) is ≤±1%FS.

When the DUT is a resistive load, it is recommended to select the NC option,
so that the output speed response is fast and the life of the relay can also be
prolonged. For safety reasons, when the DUT is other types of loads, you
need to select the Out Syn option.
Remote control of output voltage and current.
Remote control of output On/Off state.
Remote monitoring of output voltage/current measurement and AC/DC
mode.
Clear the instrument error status.
Remote monitoring of output On/Off state, load status and error status.
