The 40-251-121 is a programmable resistor module with 2 channels which can be set between 1.5Ω and 925Ω with 0.25Ω resolution
The 40-251 range provides a simple solution for applications requiring up to 2.5W of power handling per channel.
The 40-251 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 40-251 range is available in 50 standard builds that suit the most common configurations:
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.
