The GE-Emerson IC693ALG220 4-Channel Analog Voltage Input Module is a programmable logic controller that provides four input channels and converts an analog input signal to a digital signal for use in relevant applications. Inputs must be within ±11V of COM, including any noise present on the inputs. Conversion speed for each of the four channels is one millisecond. This provides an update rate of four milliseconds for any channel. Resolution of the converted signal is 12 bits binary (1 part in 4,096). User data in the %AI registers is in 16-bit 2's complement format.
