Description:
The TC620/621 are solid-state temperature sensors that are easy to program and interface with control equipment. The TC620 senses the temperature internally, and the TC621 uses an external thermistor. Figure 1 shows how the devices are connected. The data sheet for the TC620/621 describes how to calculate the correct resistance value for any desired temperature. It also gives a graphical depiction of the outputs for varying temperatures.
