The XFQ-40B multi-channel signal generation verification instrument is an improved version of the SFX-2000 multi-channel signal generator. In addition to the original signal output function of the A-type instrument (where voltage output can only be used as a signal source and cannot be used as a power supply; each output has protection function), it also adds signal measurement function.
The XFQ-40B multi-channel signal generator/calibrator can simulate a total of 11 instrument signals, including 0~10 mA, 4~20 mA, 0~5V, 0~100 mV, 0~1000 Hz, 0~10000 Hz, and 0~390 Ω, from various instrument sensors and transmitters. It can also measure instrument signals of 0~20 mA, 0~20 V, 0~200 mV, and 0~20000 Hz. In addition, it provides a DC24V loop power supply, making it fully suitable for debugging and calibration of new generation automation instruments, automatic control systems, etc. With our XFQ-40B product, multiple instruments can be independently and accurately debugged and calibrated simultaneously without the need for other instruments.
