What Are the Key Advantages of the PET-7H16M I/O Module?
The key advantages are its extremely high sampling rate, robust data storage capacity, and support for the ubiquitous Modbus TCP protocol over Ethernet. The ICP DAS PET-7H16M module offers eight 16-bit analog input channels with a sampling rate of up to 200,000 samples per second (kS/s) per channel. This capability, combined with a 30,000,000-sample memory capacity, makes it ideal for high-speed data acquisition in industrial control and testing applications.
ICP DAS has released a new high speed Ethernet input-output module PET-7H16M with support of Modbus TCP protocol featuring the sampling rate of up to 200 kS/s per channel. The module also provides 4 digital input channels and 4 digital output channels.
What is a High-Speed Modbus TCP I/O Module?
A high-speed Modbus TCP I/O module is a device designed for fast, accurate measurement and control, communicating data directly over an Ethernet network using the standard Modbus TCP protocol. The PET-7H16M module includes not only high-speed analog inputs but also four digital input channels and four digital output channels. Furthermore, it supports flexible power options, including Power over Ethernet (PoE) or a terminal block power input (+12…+48 V DC).

Who needs this Data Acquisition Module?
This data acquisition module is needed by engineers in industrial automation and testing who require precise, high-frequency data logging and real-time event synchronization. The PET-7H16M provides advanced trigger modes, including pre-trigger and post-trigger functionality based on an external electrical signal, enabling synchronous data acquisition up to 200 kHz. This is critical for capturing transient events in industrial processes.
Analog input features:
The continuous polling of analog channels with the rate of up to 30 kHz per channel and transmission to the PC is possible.
The limited sampling with transmission to the PC at the rate of up to 200 kHz per channel is possible.
The memory capacity allows the storage of up to 30 000 000 samples - 125 seconds at a sampling rate of 30 kHz, and up to 19.6 seconds at a sampling rate of 200 kHz.
Trigger modes:
- Software trigger - the acquisition of data samples begins/ends with a command from the PC.
- External trigger for the selected acquisition - the acquisition of data samples begins/ends after an external electrical signal.
- External trigger for the continuous acquisition - the acquisition of data samples goes synchronously with an external electrical signal.
External trigger for the selected acquisition features:
The external trigger allows beginning/stopping the data sampling with the rate of up to 200 kHz.
- Pre-Trigger – the module performs acquisition and, once an external trigger signal is received, it stops the acquisition and transfers the data to the PC.
- Post-Trigger – the module starts the acquisition, once an external trigger signal is received.
For the operation with PET-7H16M, there are VC, C#, VB.NET API and LabVIEW Toolkit libraries available.
For PET-7H16M please read the manual and specification.
How helps this I/O Module to simplify system integration?
This I/O module simplifies system integration by providing standard Ethernet connectivity with Modbus TCP support and readily available software libraries. The PET-7H16M offers API libraries for popular programming environments like LabVIEW, VC, C#, and VB.NET, allowing engineers to quickly develop applications for continuous polling of analog channels or limited high-speed sampling. Additionally, 1500 V DC Ethernet isolation ensures reliable operation and protection within electrically noisy industrial settings.
