High-speed analog input card

May 2003 PLCs, DCSs & Controllers Access Control & Identity Management

An isolated high-speed analog input card for the PCI-bus provides 32 analog input channels with a sampling rate of up to 100 kS/s, 12-bit resolution and 2500 V d.c. isolation protection.

Available from ProMicro, the PCI-1713 features an automatic channel/gain scanning circuit. This design allows the user to perform multichannel sampling with different gains for each channel, and with different combinations of single-ended or differential inputs.

The onboard FIFO buffer can store up to 4K A/D samples and generates an interrupt signal when the FIFO is half full. This provides continuous high-speed data transfer and more predictable performance on a Windows system.

Three kinds of trigger modes for A/D conversion are supported: software triggering, internal pacer triggering and external pacer triggering. The software trigger allows users to acquire a sample while the internal pacer triggers continuous high-speed data acquisition. The PCI-1713 also accepts external trigger sources, allowing synchronous sampling with external devices.
