Overview
The 40-263-402 is an 8-channel PT500 RTD Simulator. The 40-263 range is a cost effective method of simulating PT100,
PT500 or PT1000 RTDs. It supports 4, 8, 12, 16, 20 or 24 channels in one or two PXI slots. Also, channels are able
to be set as short or open circuit to simulate faulty wiring to a sensor.
The module is available with resistance ranges of 40Ω to 900Ω for PT100 simulation, 200Ω to 4500Ω for PT500 simulation
or 400Ω to 9000Ω for PT1000 simulation. All versions are suitable for simulating a temperature range of approximately
-150°C to >+850°C for their given sensor type. The use of resistance value calls makes programming simple, an
API to convert temperature requests to resistance calls using a model of the sensor being used is also available.
Each channel can operate with a differential input voltage range of greater than ±15V relative to a defined common mode
voltage. The common mode voltage can be set to 0V, +12V, -12V or an external source of up to ±50V.
The X40-263 provides a convenient system for verifying channel resistance using an external DMM connected to the calibration
port. The system allows cascading so one DMM can be used for the verification of multiple modules. Verification can
be performed while the UUT is connected to the module.
Calibration cables are available for this module: 40-975-009
