Speedgoat offers a range of programmable resistor modules with up to 18-channels of 8-bit resolution resistor chains in a single PCI slot.

The flexible architecture of our programmable resistor modules allows the card to also be supplied in 12-bit, 16-bit or 24-bit resolution versions, for applications requiring finer resolution, greater resistance range, or higher channel count.

These I/O modules are ideal for simulating the sensors for control and management systems under test, allowing the user to verify system response in design verification or manufacturing test applications.

All switches use instrument grade reed relays with low thermal offset voltage to ensure accurate operation under all conditions and a long service life. For maximum accuracy an on-board EEPROM allows accurate calibration data to be recorded for each resistor in the chain.

Each I/O module comes with Simulink Real-Time™ driver blocks, Simulink test models, a cable, terminal board, and comprehensive documentation.
