The HW-20B multi-channel signal generator/calibrator can simulate sensors and transmitters of various industrial process instruments, output 11 standard signals simultaneously, and measure various signals generated by process instruments. Therefore, it is suitable for debugging and calibration of new generation automation instruments and automatic control systems. Due to the fact that the HW-20B is equipped with a 24VDC output for testing two-wire instruments, the use of the HW-20B multi-channel signal generator/calibrator allows for easy and accurate debugging and testing of multiple instruments without the need for additional instruments.
