Introduction

The PET-7H24M is a high speed data acquisition device 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.
