Intelligent Technologies (IT.) D77A I/O Module Products Theory of Operation The IT. D77A I/O system consists of a collection of input and output modules connected together by QCPort to a network adapter. The network adapter connects to the industrial network where the controller usually is a PLC or DCS. The input modules collect digital or linear signals from sensors (limit switches, proximity sensors, temperature transmitters, etc.) and deliver these data to the control device.
Intelligent Technologies (IT.) D77A I/O Module Products I/O Function Discrete Input Modules Figure 17 illustrates the basic signal processing operation. When a signal is present at the input point, the module responds with the following sequence: 1. Optical Isolation — Optical isolation protects the I/O circuits and communication circuits from possible damage due to transients and over-voltage. 2.
Intelligent Technologies (IT.) D77A I/O Module Products Discrete Combination Modules Combination modules have the properties of both input and output points in a single module. The behavior of the combination module’s input and output points are the same as those found in discrete input and output modules.
Intelligent Technologies (IT.) D77A I/O Module Products Analog Input Modules Figure 20 illustrates the basic signal processing operation. Analog signals from four separate channels are received by a multiplexer (MUX). The MUX sequentially transfers this data to an analog-to-digital converter (ADC). The ADC measures the analog signal and converts it to a digital value. This digital value is presented to the controller’s central processes unit (CPU).
Intelligent Technologies (IT.) D77A I/O Module Products Analog Output Modules Figure 21 illustrates the basic signal processing operation. Digital data from external sources are extracted from the QCPort and transferred to the controller’s central processor unit (CPU). The digital data from the CPU is transferred to the digital-to-analog converters (DAC). The DAC system converts the digital values to linear signals and provides them to the output terminals.
