PET-7H16M PoE Ethernet High Speed Data Acquisition Module With 8-ch 16-bit Simultaneously Sampled AI, 4-ch DI, 4-ch DO

Description

The PET-7H16M is an high speed data acquisition devices built-in a Ethernet communication port for data transfer over the network and it includes eight high speed 16-bit single-ended analog inputs (200 KHz sample and hold for 8 channels), 4-channel digital inputs and 4-channel digital outputs. It provides programmable input range on all analog channels (±5 V and ±10 V), digital output can be set output with Short-circuit protection and overload protection. The counter value of 4-channel Low-speed DI counters and 1-channel High-speed counter are latched by ADC sampling time synchronously.

PET-7H16M also has qualification for 4 kV ESD protection as well as 2500 VDC intra module isolation. In addition, the 16-bit ADC includes built-in anti-aliasing filtering to adjust the appropriate sampling rate and filter out modulator and signal noise. The PET-7H16M is not only suitable for a wide range of mobile/portable measurement applications, but also for precision signal measurement.

Data Transmission Mode

After starting A/D acquisition, data is continuously transmitted to the Host PC

• After starting A/D acquisition, the data will be temporarily stored in the memory on the PET-7H16M module, and wait until a command is received from the Host PC, before transferring the collected data to the Host PC
• The memory capacity allows temporary storage of up to 30 million data samples, Storage time:
  (a) 125 seconds at a sampling rate of 30 kHz
  (b) 19.6 seconds at a sampling rate of 200 kHz

1. Continuous Transmission (Maximum sampling rate of 30 kHz per channel)
2. After collecting N data samples, the data is transferred to the Host PC (Maximum sampling rate of 200 kHz per channel)
