Availability: Obsolete
OBSOLETE SNAP 32-Ch -10VDC to +10VDC Analog Input Module

Production Specification

*** NOTE: This part is OBSOLETE and no longer available. ***
Please consider SNAP-AIV-32 or contact Opto 22 Pre-Sales engineers for more information.

The SNAP-AIV-32-FM analog input module provides 32 channels of analog voltage input. Each channel can be configured for -10 to +10 VDC or -5 to +5 VDC operation. Although the 32 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 brains and on-the-rack controllers.

For field wiring, use the SNAP-HD-CBF6 wiring harness with flying leads, or the convenient SNAP-AIV-HDB-FM breakout board with a SNAP-HD-BF6 cable.

Other options: Build your system in the SNAP I/O Configurator.
