Module thu thập dữ liệu tốc độ cao 4 kênh AI+ 2 kênh AO+ 3 kênh DI, 4 kênh DO ICP DAS PET-7H24M CR

The PET-7H24M is a high speed data acquisition devices with a built-in Ethernet communication port for data transfer over a network, and includes 4 high-speed 24-bit differential Analog input channels (128 kHz sample and hold for all 4 channels), 2 Analog Output channels, 3 Digital Input channels, 4 Digital Output channels and 1 Encoder Input channel.

The module provides a programmable input range on all analog channels, and the Digital Output can be set to output with short-circuit and over load protection. 1 Encoder Input channel can be configured as Quadrant, Pulse/Direction or CW/CCW input mode. The PET-7H24M also provides 4 kV ESD protection as well as 2500 VDC intra-module isolation. In addition, the 24-bit ADC includes built-in Sinc3 filtering to adjust the appropriate sampling rate and filter out modulator and signal noise. The PET-7H24M is not only suitable for a wide range of mobile/portable measurement applications, but also for precision signal measurement.

1. High speed acquisition via Ethernet

Ethernet has many advantages such as standard reliability, easy installation, long transmission distance and fast transmission speed. Its openness and popularity are not only widely used in the integration of IT, enterprise and field, but also become the mainstream specification for industrial communication.
At present, most of the high-speed synchronous data capture systems are mostly collected by a computer host with data capture cards. When the number of channels increases, more data is needed to capture the card. If the devices to collect data are distributed across multiple sites, you will need to increase the number of computer hosts. At this time, the PET-7H16M/PET-7H24M is used instead of the configuration of the computer and data capture card. The data collected from different sites can be transmitted to the central monitoring computer through the network, which can greatly reduce the complexity and time cost of the built wiring, and has the advantages of real-time monitoring. Of device status and centralized data management. The module can be used for continuous data acquisition, high-speed interval acquisition, and simultaneous acquisition with multiple channels. The maximum acquisition speed of each AI channel can exceed 100 kHz. It is suitable for high-speed data acquisition of various mechanical, electronic and physical signals in industrial production, automatic control, electrochemistry, medicine, etc.

2. Temperature, vibration, strain high speed measurement application

The SG-3000 Series Signal Conditioning Module can be connected to a variety of sensors for current, voltage, thermocouple, resistance temperature sensor (RTD), strain gauge (Strain Gauge), accelerometer Different input signals such as (IEPE Accelerometer) are filtered, isolated, amplified, and converted into an analog voltage or current output in the general measurement range. PET-7H16M/PET-7H24M plus SG-3000 series signal conditioning module will not only monitor voltage, current, temperature, strain, vibration and other diversified signals, but also collect real-time data from different regions and transmit it to the central management system via Ethernet.

3. High voltage and high current high speed measurement application

DN-800 series is a Voltage Attenuator and Current Transformer designed for used in high-voltage and high-current applications. The high-voltage and high-current can be converted into ±10 Vpp attenuated signal, and PET-7H16M/PET-7H24M is able to read the ±10 VDC signals via DN-800 series.
By using DN-800 series and PET-7H16M/PET-7H24M, the power data of all kinds of machines and AC/DC motors can be high-speed measured and retrieved, and then the analyzed data can be quickly used to develop a model to build a failure warning system.
