SNAP 4-Ch -20mA to +20mA Analog Current Input Module

Data Sheet

The SNAP-AIMA-4 provides four channels of -20 mA to +20 mA analog current input. The module does not supply loop excitation current. Although the four channels are not isolated from each other, the module is transformer isolated and optically isolated from other modules and devices.

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.

NOTE: This module can be used with SNAP Ethernet-based brains and on-the-rack controllers. See SNAP-AIMA for a two-channel module that can also be used with legacy SNAP serial brains.

For a similar module with 32 channels, see the SNAP-AIMA-32 (requires a SNAP PAC brain or R-series controller).

For a similar module that provides two isolated channels, see SNAP-AIMA-i.

For a module that provides two isolated channels and supplies loop excitation, see SNAP-AIMA-iSRC.

Build your system in the SNAP I/O Configurator.

Case Study: AAQUA NV

Antwerp-based AAQUA NV has specialized in engineering and constructing industrial wastewater treatment plants since 1999, with customers all over the world. Where possible, the company also adds value to customer waste, either by recycling wastewater to drinking water quality or by capturing the energy in the water to reduce fuel costs.

Initially AAQUA often worked with a subcontractor to automate treatment, but in 2005 they began offering automation themselves. To do so, the small company needed an automation system that was Ethernet based, flexible, reliable, offered remote access, and was easy to learn.

In this case study, read how they found that system and how they use it today.
