產(chǎn)品細節(jié): 1794-IF8IH 是具有隔離輸入的HART模擬模塊
Alen-Bradley 1794-IF8IH FLEX /0模塊是具有隔離輸入的HART模擬模塊,它已被北美危險場所認證標(biāo)準(zhǔn)批準(zhǔn)在危險的工業(yè)環(huán)境中安全運行Alen-Bradley 1794-IF8H FLEX 1/0模塊有8個離輸入,也是單端輸入。它與Alen-Bradley Flex l/0 1794-TB3 1794-TB3S終端基座兼容。它使用適馬-德爾塔轉(zhuǎn)換類型,可以處理單極性和雙極性分辨率,其單極性分辨率為16位,雙極性分辨率為15位加號。該FLEX /0模塊的外部DC電范圍為19.2至31.2伏DC,交流紋波為5%。它的尺寸是3.7 x 3.7 x 2.6英寸。
Alen-Bradley 1794-IF8IH FLEX /0 HART模擬模塊經(jīng)過工廠校準(zhǔn),但如果模塊的預(yù)期應(yīng)用需要現(xiàn)場校準(zhǔn),也可以進行現(xiàn)場校準(zhǔn),它在5優(yōu)DC下具有80毫安的Flexbus額定電流,該模塊在31.2伏DC下的最大功耗額定值為4.8瓦,在31.2伏DC下的最大散熱額定值為每小時16.4 BTU。Allen-Bradley 1794-1IF8IH FLEX /模塊可以在32至131華氏度的溫度范圍內(nèi)安全運行,并且具有開放式外殼。它所需的電線尺寸將取決于它所安裝的終端基座,但是電線必須始終被屏蔽,并且它應(yīng)該在信號端口上的2類電線中,在電源端口上的3類電線中

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
