ICTD Temperature Input Module, Eight Channels

Description

The SNAP-AICTD-8 module provides temperature input data

from any industry-standard Integrated Circuit Temperature

Device (ICTD). It has eight channels of input. The SNAP-AICTD-

8 can be used only with SNAP PAC brains and rack-mounted

controllers (standard wired and Wired+Wireless models).

The simple two-wire connections are made to the terminal

strip on top of the module. Up to 2,000 feet of ordinary hook-

up wire is used to connect the sensor to the input terminal

strip.

The module is compatible with all industry-standard ICTD

probes, including the AD-590 family from Analog Devices and

Opto 22’s part number ICTD.
