The RTD Simulator Cards (50-262) contain six resistance channels each with exceptional resistance stability and fine setting resolution characteristics. The 50-262 PCI RTD simulator range is offered with two resistance ranges – 90 to 250 Ohm and 900 to 2500 Ohm with the PT100 version providing 8 mOhm setting resolution. Each programmable resistor can be programmed with resistance calls which set the resistance of the module to an accuracy of 0.1%

The Strain Gauge Simulator Cards (50-265) are offered with six bridge channels; each channel simulates a strain gauge bridge. Four different models are offered in the 50-265 PCI strain gauge range, they include 350 Ohm, 1 kOhm, 2 kOhm and 3 kOhm bridges. Each model allows fine adjustment of the bridge resistance to emulate high or low stresses using simple resistance calls. Each channel has a stored value corresponding to the bridge being in balance.

Both of these PCI precision programmable resistor solutions are part of a growing family of switching and simulation products available from Pickering Interfaces in the mature PCI format. “PCI is used extensively in budget conscious test systems using Industrial PC chassis especially for Hardware-in-the-Loop (HIL) simulation,” explains Keith Moore, Managing Director at Pickering Interfaces, adding that against the background of high demand the vendor plans to further expand its range of PCI switching products to address those market opportunities.
