The 40-262 is a 3U PXI module range that supports 6 (in one slot), 12 or 18 (in two slots) channels of RTD simulation. Based on the 40-260 design principles the module can provide a setting resolution of <8mΩ (PT100) or <90mΩ (PT1000) and a resistance accuracy of better than 0.1% on all channels. Each simulation channel is able to provide a short or open circuit setting to simulate faulty wiring connections to a sensor. Calibration or verification of each resistor channel can be verified by using the calibration port connected to a high performance DMM and a supplied software package.

Each module can be specified with a resistance range of either 90Ω to 250Ω suitable for PT100 simulation (40-262-001/201/101), or 900Ω to 2500Ω suitable for PT1000 simulation (40-262-002/202/102). Both resistance ranges are suitable for simulating a temperature range of approximately -25°C to 410°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, (input range of at least ±15V), +12V (input range of -3V to +27V), -12V (input range of -27V to +3V)  or an external source up to +/-50V.

Calibration cables are available for this module: 40-975-009
