OPTO 22 - SNAP-AOA-23 _ SNAP 2-Ch 4-20 mA Current Loop Analog Output Module

Quick Specs:

SNAP 2-Ch 4-20 mA Current Loop Analog Output Module

The SNAP-AOA-23 provides two channels of analog current output at a nominal range of 4-20 mA. An external loop power source is required for the current loops. Although the two channels are not isolated from each other, the module is transformer isolated and optically isolated from other modules and devices. The module 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.

If you need channel-to-channel isolation and loop sourcing, see SNAP-AOA-23-iSRC.
