SNAP-AICTD (Two channels)
Four-channel module wiring is shown on the next page.
IMPORTANT: The mounting rack connector has 24 pins; the
module connector has 20 pins. The extra pins on the
mounting rack connector prevent misalignment of the
module during installation.
Description
SNAP-AICTD and SNAP-AICTD-4 modules provide
temperature input data from any industry-standard Integrated
Circuit Temperature Device (ICTD). The SNAP-AICTD has two
channels, and the SNAP-AICTD-4 has four channels. See the
table on
I/O processor compatibility.
The simple two-wire connections are made to the pluggable
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.
Both modules are compatible with all industry-standard ICTD
probes, including the AD-590 family from Analog Devices and
Opto 22’s part number ICTD.
