Thermistor Input Module 0–40 K, 0–20 K, 0–10 K, or 0–5 K Ohm
Description
The SNAP-AIR40K-4 module provides four channels of analog
to digital conversion, ideal for thermistors used in HVAC
applications or for reading the resistance of potentiometer
input. See the table on
The default input range is 0 to 40 K Ohms. The module can
also be configured for 0 to 20 K, 0 to 10 K, or 0 to 5 K Ohms.
NOTE: Resistance probes must be isolated from each other.
SNAP-AIR40K-4
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.
