NXI-5102 series overview
The NXI-5102-1000 emulates an adjustable resistance across its test terminals for insulation resistance simulation in high-voltage circuits. It is a resistance module, not a voltage source or an instrument that measures a device’s insulation resistance. The single module has one channel and a setting range of 200 kΩ to 61 MΩ. Operating voltage reaches 1,000 V DC, while resistor power and switching current must be considered when designing the test sequence. The module can be integrated into an NXI-F1000 chassis or operated individually with a 12 V DC supply and LAN or CAN connection. Applications include insulation simulation, high-voltage resistance boxes, BMS test systems and other ATE systems.
Key benefits
Up to 1,000 V DC
The voltage range supports resistance simulation in high-voltage test circuits within the power limits.
Fine adjustment
100 Ω resolution enables graduated resistance setpoints.
One channel per module
The defined single channel can be integrated into a modular test setup.
Remote control
The LAN port supports PC connection of the individually powered module.
System integration
The CAN interface provides another communication path for integration.
Short switching times
Closing in less than 1.1 ms and release in less than 0.1 ms support timed test sequences.
Operating principle and permissible operating point
The module presents a programmed resistance at its banana socket terminals. The resistance setpoint is controlled remotely; in individual operation, an external 12 V DC connection powers the module. Maximum resistor power is 3 W and maximum current during switching is 10 mA. At a given voltage, the selected resistance must keep U²/R at or below 3 W. The full setting range is therefore not available at every voltage up to 1,000 V. Make connections with the supply switched off and design the test setup for the applied high voltage.

Interfaces and operation
| Equipment | Function |
|---|---|
| Banana sockets | Connect the programmed resistance to the test circuit |
| LAN | PC connection and control in individual operation |
| CAN | Communication interface in individual operation |
| NXI rear connectors | Communication, control and power supply in the NXI-F1000 chassis |

Frequently asked questions
Does the module measure insulation resistance?
No. It provides a programmable resistance for simulation in the test circuit.
Can the lowest resistance be used at 1,000 V DC?
The voltage rating alone does not establish this. The 3 W limit constrains the resistance at 1,000 V; the 10 mA limit also applies during switching.
Can the module operate without an NXI chassis?
Yes. Individual operation uses an external 12 V DC supply and a suitable communication connection.
How is the resistance set?
The PC application supports direct resistance setting; Modbus-RTU and SCPI are also available for control.
How fast does the module switch?
Specified closing time is less than 1.1 ms and release time is less than 0.1 ms.
Can it be used in BMS test systems?
Yes, as a programmable resistance element for defined insulation conditions; the overall test system must be designed accordingly.
Can it be used in a high-voltage resistance box?
Yes. The module can be used for this purpose; voltage, current and the 3 W power limit define permissible settings.
Technical consultation and project enquiry
For selection, please specify the voltage range, required resistance values, switching sequence, interfaces and whether the module will be used in a chassis or individually.
