产品细节: 1794-IF8IH 是具有隔离输入的HART模拟模块
Alen-Bradley 1794-IF8IH FLEX /0模块是具有隔离输入的HART模拟模块,它已被北美危险场所认证标准批准在危险的工业环境中安全运行Alen-Bradley 1794-IF8H FLEX 1/0模块有8个离输入,也是单端输入。它与Alen-Bradley Flex l/0 1794-TB3 1794-TB3S终端基座兼容。它使用适马-德尔塔转换类型,可以处理单极性和双极性分辨率,其单极性分辨率为16位,双极性分辨率为15位加号。该FLEX /0模块的外部DC电范围为19.2至31.2伏DC,交流纹波为5%。它的尺寸是3.7 x 3.7 x 2.6英寸。
Alen-Bradley 1794-IF8IH FLEX /0 HART模拟模块经过工厂校准,但如果模块的预期应用需要现场校准,也可以进行现场校准,它在5优DC下具有80毫安的Flexbus额定电流,该模块在31.2伏DC下的最大功耗额定值为4.8瓦,在31.2伏DC下的最大散热额定值为每小时16.4 BTU。Allen-Bradley 1794-1IF8IH FLEX /模块可以在32至131华氏度的温度范围内安全运行,并且具有开放式外壳。它所需的电线尺寸将取决于它所安装的终端基座,但是电线必须始终被屏蔽,并且它应该在信号端口上的2类电线中,在电源端口上的3类电线中
Product introduction
Product Details: The 1794-IF8IH is a HART analog module with isolated inputs
The Alen-Bradley 1794-IF8IH FLEX /0 module is a HART simulation module with isolated inputs that has been approved by the North American Hazardous Place Certification Standard for safe operation in hazardous industrial environments. The Alen-Bradley 1794-IF8H FLEX 1/0 module has 8 isolated inputs. Also single-ended input. It is compatible with the Alen-Bradley Flex l/0 1794-TB3 1794-TB3S terminal dock. It uses the Sigma Delta conversion type and can handle both unipolar and bipolar resolutions, with a unipolar resolution of 16 bits and a bipolar resolution of 15 bits plus. The FLEX /0 module has an external DC range of 19.2 to 31.2 volts DC and an AC ripple of 5%. It measures 3.7 x 3.7 x 2.6 inches.
The Alen-Bradley 1794-IF8IH FLEX /0 HART analog module is factory calibrated, but can also be field calibrated if the module's intended application requires field calibration, and it has a Flexbus current rating of 80 mA at 5 optimal DC. The module has a maximum power consumption rating of 4.8 watts at 31.2 volts DC and a maximum heat dissipation rating of 16.4 BTU per hour at 31.2 volts DC. Allen-Bradley 1794-1IF8IH FLEX/module can operate safely in a temperature range of 32 to 131 degrees Fahrenheit and has an open housing. The size of the wire it needs will depend on the terminal base it is mounted on, but the wire must always be shielded, and it should be in the Class 2 wire on the signal port and the Class 3 wire on the power port
