SET 1220 – Capacitance Simulation Card
The SET-1220 device is a designed capacitive fuel sensor emulation for NI-SLSC. This card provides eight isolated channels that can emulate capacitance values between 10pF and 800pF. It was designed to emulate capacitive sensors that are typically connected between an excitation voltage on one end and a virtual ground on the other end.
The SET-1220 can be driven through the RTI or through the SLSC chassis via software. RTI inputs are compatible with LVCMOS, LVTTL and TTL logic levels, have low leakage current and offer 24 SPI channels. They are grouped into four by six channels with common clock and slave select signals.
Each emulation channel has its individual enable input to physically disconnect the current output via a relay. A second relay allows to short circuit the emulation input/output. This feature can be used for failure injection and DUT calibration.
