1. Introduction
The PET-7H24M is an high speed data acquisition devices built-in a Ethernet communication port
for data transfer over the network and it includes 4 high-speed 24-bit differential Analog input
channels analog inputs (128 KHz sample and hold for 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.
PET-7H24M supports more kinds of trigger modes for A/D conversion: software trigger, analog
Input trigger. The software trigger can acquire a sample whenever needed, Analog input trigger
mode, when the analog input value is higher or lower than the set specific voltage value, it triggers,
and the A/D collection of N data is started.

1.1. Features
The PET-7H24M series family offers the most comprehensive configuration to meet specific
application requirements. The following list shows the features designed to simplify installation,
configuration and application.
Data transmission mode
1. Continuous transmission (Maximum sampling rate of 60 kHz per channel)
After starting A/D acquisition, data is continuously transmitted to the Host PC.
2. After collecting N data samples, the data is transferred to the Host PC (Maximum sampling
rate of 128 kHz per channel)
a. After starting A/D acquisition, the data will be temporarily stored in the memory on the
PET-7H24M module, and wait until a command is received from the Host PC, before
transferring the collected data to the Host PC.
b. The memory capacity allows temporary storage of up to 30 million data samples,
Storage time:
(b1) 125 seconds at a sampling rate of 60 kHz
(b2) 62.5 seconds at a sampling rate of 128 kHz

A/D trigger mode
1. Software A/D Data Acquisition mode
The A/D acquisition parameters are configured via a command from the Host PC. The
continuous A/D acquisition or the acquisition of N data samples begins after the
command is triggered.
2. Analog Input Trigger mode
The A/D acquisition parameters are configured via a command from the Host PC, When
the analog input value is higher or lower than the set specific voltage value, the A/D
acquisition of the N data is started.
Analog Input Trigger
Analog Input Trigger is triggered when the voltage signal of the specified analog input
channel is higher or lower than a certain voltage setting. In addition, the user can also
specify the trigger voltage level range of the input signal. Once the signal leaves the high and
low level region or the signal enters the high and low level region, it is triggered to start the
acquisition.
1. Above High: The signal is triggered above the high level and collects N data.
2. Below Low: The signal is triggered below the low level and collects N data
PET-7H24M Series User Manual, version 1.0.0 P.7
3. Leave-region: Trigger when the signal leaves the high and low level region, collect N data
4. Entry-region: Trigger when the signal enters the high and low level region, collect N data
PET-7H24M Series User Manual, version 1.0.0 P.8
Built-in Web Server
Each PET-7H24M module has a built-in web server that allows users to easily configure,
monitor and control the module from a remote location using a regular web browser.
Communication Security
Account and password are required when logging into the PET-7H24M web server. An IP
address filter is also included, which can be used to allow or deny connections with specific
IP addresses.
Modbus/TCP Protocol
The Modbus/TCP slave function on the Ethernet port can be used to provide data to remote
HMI/SCADA software built with Modbus/TCP driver.
Automatic MDI / MDI-X Crossover for Plug-and-play
RJ-45 port supports automatic MDI/MDI-x that can automatically detect the type of
connection to the Ethernet device without requiring special straight or crossover cables.

Highly Reliable Under Harsh Environment
PET-7H24M is housed in a metal shell/case with a column-like ventilator that helps to cool
the working environment inside the shell/case.
Operating Temperature: -25 ~ +75 °C
Storage Temperature: -30 ~ +80 °C
Humidity: 10 ~ 90% RH (non-condensing)
PoE
The PET-7H24M 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,
PET-7H24M Series User Manual, version 1.0.0 P.10
higher efficiency in systems design, and faster turnaround time in set-up and
implementation. The PET-7H24M module feature true IEEE 802.3af-compliant (classification,
Class 1) Power over Ethernet (PoE) using both Ethernet pairs (Category 5 Ethernet cable).
The PET-7H24M 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 PET-7H24M module can be used in a
standard Ethernet (non-PoE) system.
When using PoE devices like 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 ~ +55VDC.

2. Getting Started
If you are a new user, begin with this chapter, it includes a guided tour that provides a basic
overview of installing, configuring and using the PET-7H24M.
Before starting any task, please check the package contents. If any of the following package
contents are missing or damaged, contact your dealer on distributor.
Before you work with the PET-7H24M, you should have a basic understanding of hardware
specification, such as the dimensions, the usable input-voltage range of the power supply, and the
type of communication interfaces.
For more information about the hardware details, please refer to “1.2. Specification”
For more information about the hardware dimensions, please refer to “1.6. Dimension”

2.1. Mounting the Hardware
The PET-7H24M can be mounted either directly to a wall/panel.
Step 1: Use the included screws and a screw driver to attach the PET-7H24M to the wall/panel
Step 2: Fasten the screws securely
PET-7H24M Series User Manual, version 1.0.0 P.25
2.2. Deploying a Basic PET-7H24M System
Here is a simple application for using the PET-7H24M that is shown below.
There are two ways for the PET-7H24M module getting the power. One is through Ethernet by a
PoE switch; the other is as usual through wiring by an external power. External power should
range from +12 VDC to 48 VDC. The reason we keep the second way is because it might be useful
if someday or somehow you have different applications. PET-7H24M module is equipped with a
LED, which indicates whether the power is supplied by a PoE switch.
PoE
i. Connect PC to the Ethernet port via the PoE switch.
ii. Connect the power supply to the PoE switch, which supplies power to the PET-7H24M.
