VDIV10:1
VDIV10:1
Orderable10-to-1 Voltage Divider Terminal Input Module
Overview
The VDIV10:1 uses precision resistor networks to bring sensors with high output voltages into your data logger’s common mode range, allowing your data logger to measure the sensor. The VDIV10:1 divides the sensor’s signal voltage by a factor of ten.
Technical Description
The VDIV10:1 contains a 90 kΩ resistor and a 10 kΩ resistor. Both resistors have a ratio tolerance of ±0.02%.
The maximum input voltage into the VDIV10:1 should not exceed ±50 V. Increased input settling time may be necessary to accommodate the relatively high resistance of the voltage divider.

Data Logger Considerations
The VDIV10:1 uses two adjacent single-ended analog inputs (one differential channel); an adjacent analog ground channel accepts the "ground prong" of the VDIV10:1. 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 VDIV10:1 attached; older CR10TCRs are not deep enough.
Programming
The VDIV10:1 is measured with either the VoltSE or VoltDiff Instruction in CRBasic, and with Instruction 1 (SE Volts) or 2 (DiffVolts) in Edlog. Each VDIV10:1 can be wired to make one differential measurement or two single-ended measurements.
