SNAP 8-Ch Analog Resistor/thermistor Input, 400 K Ohms

生产规范

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.

Part of the SNAP PAC System, the module mounts on aSNAP PAC架用snap pacbrainorrack-mounted controller。模拟,数字和串行I/O模块都可以在同一机架上。这样的I/O单元也非常适合基于PC的控制或用作智能遥控器I/O用于Allen-Bradley Logix PLC system,例如Controllogix,Microlologix或Compactlogix。

兼容性:该模块可以与Snap Pac Brains和R系列控制器一起使用。最小要求:大脑或控制器固件R9.3C和PAC项目R9.3002(PAC控制R9.3B)。
