7.7 External analog function (optional)
When the interface card selected by the user is DB25 analog interface (IT-
E1208), the analog interface can realize the external analog function.
The rear panel of the series is optionally configured with a DB25 analog inter-
face, through which, the following functions can be realized:
•
•
•
•
•
•
•
•
•
•
Re-Energy: indicates the regenerative power.
•
AHour: indicates the capacity of charge and discharge, when the battery
simulator function or battery test function is enabled, the capacity data
will be cleared.
•
WHour: indicates energy data, when the battery simulator function or
battery test function is enabled, the energy data will be cleared.
•
Reset Meas: clearing the energy data and capacity data.
•
Reset ReE: clearing the regenerative power data.
Remotely control voltage and current values
Control On/Off state
Remotely monitor CC and CV states as well as voltage and current values
Clear instrument faults
Monitor the instrument loading state, On/Off state and fault state
RS-485 interface connection. For detailed introduction about interface, refer

2.6.5 RS-485 Interface
Before connecting the hardware equipment that controls the analog in-
terface, ensure that the hardware equipment would not output voltage
that is 20% higher than specified value. Otherwise, it would damage the
instrument. For example, during setting of voltage or current, the input
voltage cannot exceed 12V. Otherwise, it would damage the instrument.
Under the analog remote control mode, the analog signal input pin can-
not be suspended, before enabling the external analog function on the
front panel, it is necessary to correctly connect the 1 (Vol_Pro), 15 (Cur_
Pro) and 17 (Cur/Vol_Pro).
There is safe electrical isolation between the analog interface and the
DC terminal. Do not connect any ground wire of the analog interface to
the DC+ or DC- terminal on the instrument's rear panel.
