Isolated SNAP 2-Ch 4-20 mA Current Loop Analog Output Module, with Loop Sourcing
$365.00 USD
Price in USA and Canada Only
Availability: In Stock
The SNAP-AOA-23-iSRC module provides two channels of current output with a nominal output range of 4 mA to 20 mA. The module includes built-in loop sourcing capability.
With the connection of a single 24 V power supply, the module sources two 24 V loops. The loop sources are internally connected to the individual outputs. The two channels and their loop sources are isolated from each other; they do not share any field connection. In addition, each loop source is current limited so that an external fault on one loop will not affect the other.
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 MicroLogix or other RSLogix-based PLC system, such as ControlLogix or CompactLogix.
If you need a Factory Mutual-approved version, see the SNAP-AOA-23-iSRC-FM instead.
