Overview

The 40-253-111 is a programmable resistor module with 1 channel which can be set between 1Ω and 62.1Ω with 0.25Ω resolution The 40-253 range provides a simple solution for applications requiring up to 10W of power handling per channel. The 40-253 is available in a variety of resistance ranges and resolution capabilities that meet the needs of most functional test systems. Each channel is able to simulate short or open circuit conditions that can be experienced in a system caused by faulty wiring or sensors.

The 40-253 range is available in 20 standard builds that suit the most common configurations:

  • Narrow resistance range versions, available in 1 or 2 channel variants
  • Medium resistance range version, available in 1 channel variants
  • Wide resistance range version, available in 1 channel variants

A calibration cable assembly can be attached to the module in place of the UUT to enable a DMM to be used for verifying the resistor channels, considerably simplifying the checking of the module's calibration. The associated calibration cable for this product is available for purchase as 40-975-037-1m

For applications requiring greater density with lower power, users should consider the model 40-297 high-density Precision Resistor Modules.
