XDH series PLC has EtherCAT motion control master stationfunction.
6. High speed signal acquisition(With 3-10 channels high speed counter)
By selecting different counters, it can count in singlepnase incrementalmode (tne max frequency can reach80kHz),AB phase mode (double frequency and quadruplefrequency are optional,and the max frequency can reach50KHz) and differential mode (the max frequency canreach 200kHz)
High speed control is realized by simple high-speedcounting instruction.
7. Strong expansion capability
XD series PLc basic units can be equipped with rich l/Oexpansion module, analog input and output module.temperature control module, BD board and leftexpansion module,which can easily realize analogcontrol for various purposes
The data exchange between the expansion module andthe ontology has changed from the original parallel porcommunication mode of XC series to the SPl serial portcommunication mode of XD series, so the data exchangespeed is faster than that of the original XC series (2ms/AD)

Why Must a Transformer Core Be Grounded at Only One Point? Isn't Multi-Point Grounding More Reliable?Why Does the Transformer Core Need to Be Grounded?During operation, the transformer core, along with the metal structures, parts, and components that fix the core and windings, are all situated in a strong electric field. Under the influence of this electric field, they acquire a relatively high potential with respect to ground. If the core is not grounded, a potential difference will exist between the core and the grounded clamping structures and tank, which may lead to intermittent discharge.I01/29/2026 -
