Availability: In stock
SNAP 1-Ch 4-20 mA Current Loop Analog Output Module

Production Specification

The SNAP-AOA-3 provides a single channel of digital-to-analog conversion. The module has a true differential (floating) output that eliminates ground loops and has a nominal output range of 4-20 mA. The module is transformer isolated and optically isolated from other modules and devices, and is factory calibrated.

Part of the SNAP PAC System, the module mounts on a SNAP PAC rack with a SNAP PAC brain or rack-mounted controller. Analog, digital, and serial I/O modules can all be on the same rack. Such an I/O unit is also well suited for PC-based control or for use as intelligent remote I/O for an Allen-Bradley Logix PLC system, such as ControlLogix, MicroLogix, or CompactLogix.

For a similar module with two channels, see SNAP-AOA-23.
