SNAP 8-Ch -10VDC to +10VDC Analog Input Module

Production Specification

The SNAP-AIV-8 provides eight channels of analog voltage input. Each channel can be configured for -10 to +10 VDC or -5 to +5 VDC operation. Although the eight 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.

Compatibility: This module can be used only with SNAP PAC controllers and brains.

NOTE: This module does not provide channel-to-channel isolation. If you need an isolated module, see the two-channel SNAP-AIV-i module.

Build your system in the SNAP I/O Configurator.
