Description

T797HL is a specific signal conditioning module for smart field instruments with HART (Highway Addressable Remote Transducer). The module powering the front-end equipment through the back-stage current loop collection mode and transmitting the voltage to an industry standard isolated 3.7-22mA output current. The module also offers an isolated micro-power which can be used for the peripheral devices. In addition, the module can realize the half duplex communication of the field and control area by means of an integrated HART signal channel, which greatly reduces the cost for wiring between the field and the control area also shown in detail in Design Reference. This accurate isolated voltage signal to 3.7-22mA current conversion can be used in a variety of analog instrument input ports such as PLC and DCS systems, or similar. In addition, this module has extremely small SIP9 form factor with excellent temperature drift characteristics of less than 50PPM / ℃ across the entire -40 ℃ to +85 ℃ operating temperature range. This module adopts unique electro magnetic isolation mode that allows it to withstand 2kVAC isolation test voltage between input and output.
