Multifunction data-acquisition module

Staff - August 1, 2006

The SeaI/O-470 multifunction module can handle applications such as process control, data acquisition, broadcast automation, and facility management. The module provides 16 single-ended or eight differential 12-bit analog inputs, two 12-bit digital-to-analog (D/A) outputs, eight optically isolated digital inputs, and eight open collector digital outputs. The analog-to-digital (A/D) inputs are independently software selectable for 0–5 V, 0–10 V, ±5 V, and ±10 V ranges and can be configured for measuring 0–20-mA current loop. The D/A channels are independently jumper selectable for a 0–5-V or a 0–10-V output range. Eight digital inputs are rated for 5–30 VDC and provide 300-V external isolation, while the SeaI/O-470's eight open collector outputs can be used to switch 24-V devices found in industrial control applications. The module can be connected to a host device via Ethernet, USB, RS-232, or RS-485.
