In industrial production, in order to increase the load capacity of the equipment and ensure that the equipment connected to the same signal does not interfere with each other and improve the safety performance of electronic control, it is necessary to collect, calculate, isolated, amplify, convert and deinterference signals from the instrument or sensor, and then obtain standard analog current or voltage signals commonly used in the industry, and safely send them to the secondary instrument or PLC/DCS/PC Used by the machine.Users use analog signal isolators /Isolation amplifier /Isolation change...
