The PET-7H16M/PET-7H24M is a high speed data acquisition devices with a built-in POE Ethernet communication port for data transfer over a network. PET-7H16M includes 8 high-speed 16-bit single-ended Analog input channels (200 kHz sample and hold for all 8 channels) and PET-7H24M includes 4 high-speed 24-bit differential Analog input channels (128 kHz sample and hold for all 4 channels). All high speed data acquisition modules allow A/D signal conversion simultaneously on each channel and provide the programmable input range on all analog input channels. In addition to supporting Analog Input channels, the module also provides Digital Input / Digital Output / Counter / Encoder with different combinations and different numbers of channels.

The module provides a programmable input range on all analog Input channels, and the Digital Output can be set to output with short-circuit and overload protection. The counter value of DI counters and High-speed counter are latched by ADC sampling time synchronously. The Encoder Input channel can be configured as Quadrant, Pulse/Direction or CW/CCW input mode. The module provides 4 kV ESD protection as well as 2500 VDC intra-module isolation.

The PET-7H16M/PET-7H24M supports more kinds of trigger modes for A/D conversion: software A/D trigger, external clock trigger, external digital signal event trigger (Post-trigger/Pre-trigger/Delay-trigger) and analog trigger. The software trigger can acquire a sample whenever needed, and the continuous A/D acquisition or the acquisition of N data samples begins after the command is triggered. In external clock trigger mode, the speed of the A/D acquisition and the amount of data acquired are controlled by external electrical signals. In digital signal event trigger mode, the A/D acquisition parameters are configured via a command and the A/D acquisition of the N data samples is started while triggered by an external electrical signal. The analog trigger mode triggers when the analog input value is higher or lower than the set specific voltage value, and starts the A/D acquisition of the N data.

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.

15. PoE (Power over Ethernet)
"P" of PET-7H16M means PoE function. The module has integrated Power-over-Ethernet (PoE), it allows power and data to be carried over a single Ethernet cable, so a device can operate solely from the power it receives through the data cable. This innovation allows greater flexibility in office design, higher efficiency in systems design, and faster turnaround time in set-up and implementation. The module feature true IEEE 802.3af-compliant (classification, Class 1) Power over Ethernet (PoE) using both Ethernet pairs (Category 5 Ethernet cable). The module can receive power from an auxiliary power sources like AC adapters and battery in addition to the PoE enabled network. This is a desirable feature when the total system power requirements exceed the PSE’s (power sourcing equipment) load capacity. Furthermore, with the auxiliary power option, the module can be used in a standard Ethernet (non-PoE) system.

When using PoE devices like PET-7H16M/PET-7H24M, you can choose ICP DAS “PoE” switch —“NS-205PSE” as the power source, NS-205PSE automatically detects the connected devices whether they are PoE devices or not. This mechanism ensures NS-205PSE to work with both PoE and non-PoE devices coordinately at the same time. Being as a power source for PoE devices, NS-205PSE requires its power input ranging from +46 ~ +55 VDC.
