SNAP-AIRTD
See additional wiring details on the following 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
The SNAP-AIRTD module provides a nominal input range of -200° to
+850° C.
Since both inputs share the same reference terminal, use isolated
RTD probes.
