SM620 is an 8-channel pulse input module in the SM series hardware products. The SM620_HollySys module connects to the backplane of the chassis via a 64-pin European-style connector and is used in conjunction with the corresponding terminal module. The SM620_HollySys module inputs 8 channels of pulse signals from the field. The frequency measurement and counting functions of the SM620 module can be configured according to user needs. Each channel can be set to frequency measurement function, the SM620_HollySys module can also be set to counting function, and it allows the same SM620 module to have both frequency measurement channels and counting channels.
HollySys SM620, SM711 input and output modules. SM620 adopts a modular design, with the overall structure of the SM620_HollySys module being a box-type plug-in structure, installed on the chassis rail and fixed with a latch. The backplane of the SM620_HollySys module is fixed with an anti-mixing pin. SM620 is an 8-channel pulse input module. The module adopts a chassis installation method and is used in conjunction with the corresponding terminal module via pre-made cables to input 8 channels of pulse signals from the field. The frequency measurement and counting functions of the SM620 module can be configured according to different user needs.
SM620 adopts a modular design, with an overall European-style plug-in structure, chassis installation, latch fixation, and supports hot-swapping. The module and the chassis slot are identified and positioned according to the matching anti-mixing pin, effectively preventing misalignment from causing damage to the hardware. The SM620-A05 version of the PI module only supports signal acquisition for the first 4 channels, with the acquisition function of the last 4 channels reserved; the SM620-B01 version restores 8-channel acquisition.
