Analog Inputs
e 1351 System Controller processes each of the analog input channels and makes the value available
to VCL. e parameter sets for each analog input are the same—although Analog 1-4 have a lower
input voltage limit. e analog inputs share the same set of parameters and monitor variables,
distinguished by their individual switch number as illustrated in the switches table (below). eir
usages vary as illustrated in the Figure 4 wiring diagram and as described in the (shared) Virtual
Switch parameter settings, above.
