SP-3128 is a 12bit DAC 8-channel analog output + 4-channel digital input module. Channel 0 to 3 can be programmed to output 0-20mA, 4-20mA current analog signals, and channels 4 to 7 can be programmed to output ±10V, 0-10V voltage analog signals. The module is widely used in industrial measurement and control, intelligent instruments and meters, and process control applications. It has high cost performance; RS-485 communication and analog output channels and modules provide 1500V electrical isolation, which can effectively avoid surge interference and other high-voltage shock damage.
