2. v ANALOG COMMON 958EN SIMPLIFIED SCHEMATIC THERE IS ONE PORT OF EIGHT DIFFERENTIAL CHANNELS THERE ARE TWO ANALOG COMMONS YOU MUST CONNECT ANALOG COMMON TO EARTH GROUND TO KEEP INPUT CIRCUIT FROM FLOATING Modbus TCP IP Analog Input This circuit employs one pair of fault tolerant 8 1 analog multiplexers to drive 16 channels of current or voltage inputs through input buffers to two single ended channels of a 16 bit A D converter Odd channels drive one A D channel even channels the other Additional circuitry can optionally connect each A D input to OV zero or a precision 5V reference to help accomplish calibration and self test The A D has a native input 16 bit range of 10V Units include an isolated 10 100Mbps Ethernet interface for configuration monitoring calibration and control of the I O Embedded configuration parameters are stored in non volatile memory The A D rescales the inputs via an integrated resistor divider network utilizing a series 25KQ resistor and a 17KQ divider resistor additionally coupled to an internal 5V A D reference via a series 10KO resistor The rescaled signals alternately connect to the ADC The ADC uses a successive approximation algorithm and internal sample amp hold circuit to convert the input signal to a 16 bit serial output stream which is transmitted to the CPU via an SPI interface The I O terminals and the Ethernet port terminals also include
