Analog Input Modules For Analog Input Modules, each of the three channels asynchronously measures the input signals and places the results into a table of values. Each of the three input tables is passed to its associated Main Processor using the I/O bus. The input table in each Main Processor is transferred to its neighbors across the TriBus. The middle value is selected by each Main Processor and the input table in each Main Processor is corrected accordingly. In TMR mode, the mid-value data is used by the control program; in duplex mode, the average is used. Each Analog Input Module is automatically calibrated using multiple reference voltages read through the multiplexer. These voltages determine the gain and bias required to adjust readings of the analog-to-digital converter. Analog Input Modules and termination panels are available to support a wide variety of analog inputs, in both isolated and non-isolated versions: 0 to 5 VDC, 0 to 10 VDC, 4 to 20 mA, thermocouples (types K, J, T and E), and resistive thermal devices (RTD). For specifications, see Analog Input Modules on page 46. Analog Output Modules An Analog Output Module receives three tables of output values, one for each channel from the corresponding Main Processor. Each channel has its own digital-to-analog converter (DAC). One of the three channels is selected to drive the analog outputs. The output is continuously checked for correctness by loop-back inputs on each point which are read by all three microprocessors. If a fault occurs in the driving channel, that channel is declared faulty, and a new channel is selected to drive the field device. The designation of driving channel is rotated among the channels so that all three channels are periodically tested. Each AO Module is guaranteed to remain in calibration for the life of the controller; periodic manual calibration is not required. For specifications, see Analog Output Modules on page 61. Digital Input Modules Every Digital Input Module houses the circuitry for three identical channels (A, B and C). Although the channels reside on the same module, they are completely isolated from each other and operate independently, which means a fault on one channel cannot pass to another. In addition, each channel contains an 8-bit microprocessor called the I/O communication processor which handles communication with its corresponding Main Processor. 12 Chapter 1 Introduction Planning and Installation Guide for Tricon v9–v10 Systems Each of the three input channels asynchronously measures the input signals from each point on the input termination module, determines the respective states of the input signals, and places the values into input tables A, B and C respectively. Each input table is regularly interrogated over the I/O bus by the I/O communication processor located on the corresponding Main Processor. For example, Main Processor A interrogates Input Table A over I/O Bus A. There are two basic types of Digital Input Modules: TMR and Single. For TMR modules, all critical signal paths are 100 percent triplicated for guaranteed safety and maximum availability. On Single modules, only those portions of the signal path which are required to ensure safe operation are triplicated. Single modules are optimized for those safety-critical applications where low cost is more important than maximum availability. For specifications, see Digital Input Modules on page 71. TMR Digital Input Modules On TMR Digital Input Modules, all critical signal paths are 100 percent triplicated to guarantee safety and maximum availability. Each channel conditions signals independently and provides isolation between the field and the Tricon controller.
