Overview
The CAEN Mod. R8031 provides 8 or 16 independent 100 V / 10 mA channels in a 19″ rack unit (110/220V AC Powered). Each channel can provide a 100V max voltage and a 10 mA max current. The unit is available with positive, negative and “mixed” (4-8 positive and 4-8 negative) channels.
Channels outputs are delivered through BNC connectors. The HV output RAMP-UP and RAMP-DOWN rates may be selected independently for each channel in the range 1÷50 V/s in 1 V/s steps. The module features 50 nA Iset resolution.
Module control can take place either locally thanks to a 2.8″ Touchscreen Graphic color LCD display with a completely redesigned user interface or remotely, via USB 2.0 or Ethernet.

Consult our connectors reference page for technical information.
A complete set of Software Tools is available to control these units; the user can freely download low level libraries, LabVIEW driver and Graphical application software.
Safety features allows the module to perform as a current generator and includes:
| Overvoltage and Undervoltage warning | When the output voltage differs from the programmed value by more than 2% of set value (minimum 10V). |
| Overcurrent detection | When a channel attempts to exceed the programmed current limit, it signalled to be in “overcurrent” and enter in a TRIP status. The output voltage is varied to keep the current below the programmed limit for a programmable TRIP time, then the channel is switched off. If TRIP is set to “constant current mode”, the channel behaves like a current generator. |
| Hardware VMAX and IMAX | Maximum output voltage and maximum current value can be fixed, via front panel potentiometer, at the same common value for all the board channels. IMAX and VMAX values can be read out via software. |
| Safety Board Interlock | Common Interlock logic for channels enable/disable and individual inputs signal for channel Kill function. |

Max. time an “overcurrent” can last (seconds). A channel in “overcurrent” works as a current generator; output voltage varies in order to keep the output current lower than the programmed value. “Overcurrent” lasting more than set value (1 to 9999) causes the channel to “trip”. Output voltage will drop to zero either at the Ramp-down rate or at the fastest available rate, depending on Power Down setting; in both cases the channel is put in the off state.
If trip= INFINITE, “overcurrent” lasts indefinitely. TRIP range: 0 ÷ 999.9s; 1000 s = Infinite.
