Space Temperature Sensor
Product Information Sheet
809-6590
Overview
The 809-6590 is wall mounted space temperature
sensor. It is suited for a wide variety of applications.
The temperature sensor has a 10KΩ thermistor. The
sensor has been tested by CPC to maintain less than
0.72°F error between -40 and 248°F.
Installation
The sensor connections to the input point on the 16AI
board are not polarity sensitive. The sensor is
connected as shown below in the Sensor Wiring
Diagram. The sensor can be wired to any available
point on the 16AI board. Connect one lead to the 0V
input, and connect the other lead to the SIG input.
