Thumbwheel switch multiplex input 2012-11-19

 The FBs-32DGI thumbwheel switch multiplex input module provided in FBs-PLC conduct multiplexing input scan of the eight sets of 4 digit numbers (or 128 independent ON/OFF status) via the embedded I/O ASIC chips (special chips for the FBs-PLC I/O module). It does not occupy any CPU time and the multiplexing scan rate is about 10ms. In addition, because only 24 wires are required by multiplexing input to achieve 32 digits (or 128 bit ON/OFF) input, plus that the FBs-32DGI is only 4cm in width, it turn out to be an ultra high density, lowest cost, and most labor saving solution.
