VDIV2:1 2-to-1 Voltage Divider Terminal Input Module


The VDIV2:1 uses precision resistor networks to bring sensors with high output voltages into the datalogger’s common mode range, allowing the datalogger to measure the sensor. The VDIV2:1 divides the sensor’s signal voltage by a factor of two.

Funktionen und Vorteile

  • Connects directly into data logger input terminals
  • Easy to install or remove
  • Low power consumption


Technische Beschreibung

The VDIV2:1 contains two 10 kΩ resistors that have a ratio tolerance of ±0.02%. Increased input settling time may be necessary to accommodate the relatively high resistance of the voltage divider.

Data Logger Considerations

The VDIV2:1 uses two adjacent single-ended analog inputs (one differential channel); an adjacent analog ground channel accepts the "ground prong" of the VDIV2:1. Not all data logger terminal strips have this sequence on all channels, so please check your data logger's wiring panel to confirm channel assignments, especially if you plan to use multiple terminal input modules.

Please note that if a CR10X will be used to measure thermocouples in the same application, newer CR10X Wiring Panels and the CR10XTCR Reference Thermistor (with its accompanying thermocouple cover) are deep enough to cover the data logger input channels with a VDIV2:1 attached; older CR10TCRs are not deep enough.


The VDIV2:1 is measured with either the VoltSE or VoltDiff Instruction in CRBasic, and with Instruction 1 (SE Volts) or 2 (DiffVolts) in Edlog. Each VDIV2:1 can be wired to make one differential measurement or two single-ended measurements.

  1. These two voltage dividers can handle different maximum input voltages.

    • The VDIV2:1 has a maximum input voltage of 10 V.
    • The VDIV10:1 has a maximum input voltage of 50 V.
  2. The CR1000 can measure analog voltages in the ±5 Vdc range. A voltage divider such as the VDIV2:1 is required to reduce 10 Vdc to an acceptable range. For examples of wiring and programs, see the VDIV10:1/VDIV2:1 manual

  3. The CR1000 has analog inputs that measure voltage in a ±5 Vdc range. To measure a 12 Vdc voltage, a voltage divider is needed. In its simplest form, a voltage divider comprises two resistors. Precision differential voltage dividers, such as the VDIV10:1, are available for this purpose.
