This product is a one in two out guide rail type analog signal isolator, with one 4 ~ 20mA DC signal input and the other 4 ~ 20mA DC signal input. The isolation transformer outputs two DC signals, output 1 is 4 ~ 20mADC and output 2 is 4 ~ 20mADC DC current signal; The auxiliary power supply is DC 24V. The function of cx1010 / cx1020 system is to make all Beckhoff fieldbus components (such as bus coupler, bus terminal controller and drive technology) assemble in complex system as distributed control components. At the same time, several same or different bus master stations are allowed to operate in parallel. For example, two PROFIBUS master stations or one PROFIBUS master station and one SERCOS interface master station can exist in one system at the same time.

The hybrid operation of master station and slave station connection has also become possible. A CX system can be conceived as an intelligent gateway in different fieldbuses. It receives data from the fieldbus, processes them through programs, and then provides them to other fieldbuses. Except that the CX variant is in the form of single channel, the performance data of Cx fieldbus master station module is almost the same as that of Beckhoff PC fieldbus card. The number of slave stations that can be connected is only limited by their respective bus systems. The connection of master station or slave station is used to realize the networking of several CX systems with other stations at the fieldbus level. Data transmission through Ethernet is strictly different from that through Ethernet.
