Description
The SNAP-AIR400K-8 module has eight channels of analog to digital conversion that convert resistance to temperature or to ohms. The module is ideal for NTC thermisters commonly used in HVAC, refrigeration, and process control applications. It may also be used with PTC thermisters in resistance sensing applications.
The SNAP-AIR400K-8 reads variable resistance type transducers, and it has 12 resistance input ranges from 500 Ohms to 400 K Ohms, plus Autorange. Range dependent resolution is from 20 milliohms to 16 Ohms. SNAP PAC brains and PAC Control provide direct temperature readings for four popular thermistors using the Steinhart-Hart equation. You may also enter custom coefficients for unsupported thermistor curves.
