CFP-AO-200 - NI Analog Output Module

Description

The cFP-AO-200 (Part number: 777318-200) incorporates an open-circuit location for wiring and sensor investigating and shorting out insurance for wiring mistakes. Each channel is separately configurable. To make establishment and setup less demanding, the National Instruments cFP-AO-200 highlights HotPnP (fitting and-play) tasks, so it is consequently recognized and distinguished by the arrangement programming. With the cFP-AO-200 module, the user can straightforwardly interface with mechanical actuators or units under test and gain high-exactness power. The I/O modules adjust and scale building units to sensor signals, while also performing self-diagnostics to search for issues with the module or with the wiring, such as open momentum circles. The NI cFP AO 200 module has an update rate of 200 Hz. In general, information throughput to the controller or PC relies upon the product circle speeds and the system speeds. This module incorporates eight 0 to 20 mA or 4 to 20 mA simple yield output channels (with an overranging of 0.5 mA), produced with a 12-bit DAC, and with an update rate of 200 Hz. Each yield channel incorporates a checking circuit and LED marker for open current circle location.  The NI cFP-AO-200 requires an outside power supply that gives 5 to 24 VDC. It is protected against short-circuits, and has a 2,300 Vrms transient overvoltage protection between the inter-module communication bus and the I/O channels. The NI device has a maximum conversion rate of 200 updates per second, and a slew rate of 0.4 mA per microsecond. Compact FieldPoint modules incorporate an implicit power conveyance transport that gives different power associations on the module. A field wired power supply associated with the voltage (V) and normal (C) terminals is inside associated with a power circulation transport that gives extra breakout terminals to voltage supply (VSUP) and normal (COM). These terminals give a helpful method to disperse capacity to handle gadgets that require outer power. The device weighs 3.7 oz., and measures 5.00 x 2.60 x 0.94 in. in physical dimensions. It has a recommended operating temperature range of –40 to 70 °C, and a storage temperature range of –55 to 100 °C.

One: PLC analog input module (analog input module), also known as A/D module, converts the continuous analog signal generated by the sensor detection in the field into the digital quantity that the PLC CPU can receive, generally 12-bit binary number, the more digital quantity modules, the higher the resolution. Two: PLC analog output module. The analog output module, also known as D/A module, converts the digital quantity sent by the PLC CPU to the analog output module into the analog quantity (voltage or current) that can be received by the external device. The digital signal received by the analog output module is generally 12-bit binary number, and the more digital quantity modules, the higher the resolution. The digital module is to detect the state of the external switching input. Three: Digital input and output signal is the switching signal, 0 or 1, analog signal, there are two, voltage or current signal, generally the signal transmitted by the transmitter, such as the pressure transformer to detect the pressure of the water pipe, it will output an analog signal 4-20ma or 0-10V signal to the PLC, PLC for data processing, This is the difference between a digital input module and an analog input module.

In the input sampling phase, the PLC successively reads all input status and data by scanning and stores them in the corresponding cell in the I/O image area. After the end of the input sampling, the user program execution and output refresh phase. In both phases, even if the input state and data change, the state and data of the corresponding unit in the I/O map area will not change. Therefore, if the input is a pulse signal, the width of the pulse signal must be greater than one scan cycle to ensure that the input can be read in any case. The acquisition of the switching quantity is realized through the PLC input module, which is generally a DC 24V input. The PLC provides a common point, positive or negative, and then the common point is connected to the limit switch and other devices. When the limit is closed, the path is formed and the signal is introduced into the PLC input point. Specifically why the input point to power inside the state is on, is the function of PLC itself, you do not need to tube. Through the analog module, A/D (analog/digital) module, the external weight signal, temperature signal, pressure signal can be introduced, A/D module can accept the signal is 0-10V, 0-5V, -5-5V voltage signal and 0-20MA, 4-20MA current signal. If the signal obtained by the terminal acquisition module is not these standard signals, but also through the transmitter conversion, after the standard signal enters the A/D module, it will be converted by A/D into a number, the specific range is different PLC is not the same, these converted digital quantities, can be used by the program, conversion, processing, and finally get the required data displayed.
