Product Description
Acromag IP330 16-Bit A/D Analog Input Module – High-Density IndustryPack for Data Acquisition Systems
This used Acromag IP330 is a high-density 16-bit analog-to-digital input module in the IndustryPack (IP) form factor. It is designed to mount on a carrier board (such as VMEbus, ISA, or PCI carriers) to provide precision analog input capabilities for industrial control, data acquisition, and test systems.
The IP330 offers 16 differential or 32 single-ended analog input channels with programmable input ranges (±5V, ±10V, 0-5V, 0-10V). It features a 16-bit successive approximation ADC with a maximum conversion rate of 125KHz (8µs per channel) and a recommended throughput of 67KHz for specified accuracy. The module includes programmable gain (1,2,4,8) per channel, mailbox memory for uninterrupted data acquisition, and multiple scanning modes.
The IP330 has been discontinued by Acromag and replaced by the IP330A.
Condition Note: This unit is untested and sold as-is. It is a pull from surplus test equipment. No carrier board, cables, or software are included.
