WBT2C4CU05(2 Channel 4~20mA Standard Signal Conditioner) uses linear photoelectric isolation technology to isolate and transmit 2 channel 4mA～20mA DC current signals. This product is an independent two-way three-isolation product, that is, the input, output and auxiliary power supply of each channel are electrically isolated from each other. This product has the characteristics of high accuracy, high isolation, low drift and low power consumption. It can solve the common mode interference in the signal transmission process of sensors or meters, overcome the ground loop interference and strong electrical interference caused by the long transmission distance of scattered collected signals, and especially is suitable for usage with sensors/transmitters and meters that require electrical isolation.
