PCI-6110 - NI Multifunction I/O Device

Description

The PCI-6110 (Part number: 777475-01) is a Multifunction I/O Device from National Instruments. This device offers the latest features to fulfill many measurement requirements. The PCI 6110 NI does not have any switches or jumpers. This device can perform basic measurement and analysis tasks. The PCI 6110 features both analog and digital channels. This device supports digital triggering. These features make this model ideal for stimulus/response applications. The NI PCI-6110 has four differential analog input channels. The input channels are bipolar. This device has the input range of 20 V from -10 V to +10 V, a 12-bit resolution, and a sampling rate of 5 MS/s. The input channels support both AC and DC coupling. The NI DAQ PCI 6110 offers an analog input accuracy of 252 mV. The PCI-6110 also has two analog output channels, and is equipped with a 68-pin male SCSI II type I/O connector. These channels are incorporated in the I/O connector. The output channels have a 16-bit resolution and a sampling rate of 4 MS per second. In addition to analog channels, this device features eight digital channels (with a 5 V/TTL compatibility). These channels can be programmed as input or output channels. The PCI-6110 Multifunction I/O Device supports parallel sampling. This device can read samples from different channels simultaneously. The PCI-6110 device supports NI-DAQ driver software, which enables the device to create customized automated measurements and control applications. The PCI-6110 also has a FIFO buffer, which can store 8192 samples. The device has a power requirement of +5 VDC at 2.5 A. The PCI-6110 Multifunction I/O Device is well suited for a broad range of applications, such as radar, sonar, and ultrasound technologies. This model is also ideal for industrial applications. These applications include lab automation and design verification. This device can additionally be utilized in research projects and the automation of 42 V. The NI device measures 12.3 x 4.2 in. in physical dimensions. It has a recommended operating temperature range of 0 to 45 °C, a storage temperature range of –20 to 70 °C, and a noncondensing humidity range of 5 to 90% RH.

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.
