The SNAP-AIRTD-8U analog input module provides 8 input channels, each individually software configurable. This module is commonly used for 3-wire RTD temperature inputs but is also suited to high-resolution resistance measurements. It features open circuit detection if any wire breaks.
You can individually configure each of the module's 8 points for a variety of behaviors, including a fixed temperature range for nickel, platinum, or copper RTD inputs; a fixed range in ohms; or two types of auto-ranging where the module scrolls within a range (in ohms) and chooses the best resolution.
SNAP-AIRTD-8U在顶部有一个插件端子，并带有弹簧钳连接器，可轻松接线。盒子中提供了一个带有模块的插入工具。
所有8个输入共享相同的参考终端。确保使用隔离的RTD探针。
SNAP-AIRTD-8U需要使用固件R9.5A或更高的SNAP PAC Brain或R系列控制器。该模块不能与传统的大脑或控制器一起使用。
