OPT-SNAP-AICTD-8

SNAP-AICTD-8 SNAP 8-Ch Analog Temperature Input Module - ICTD

The SNAP-AICTD-8 provides four channels of analog temperature input from any industry-standard Integrated Circuit
Temperature Device (ICTD). Simple two-wire connections are made to the pluggable terminal strip on top of the module.
Although the eight channels are not isolated from each other, the module is transformer isolated and optically isolated
from other modules and devices.
 
This module can be used with SNAP PAC brains and R-series controllers.
 
Part of the SNAP PAC System, the module mounts on a SNAP PAC rack with a SNAP PAC brain or rack-mounted
controller. (This module cannot be used with legacy SNAP brains.) 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.
