TW147HL is a specific signal conditioning module for smart field instruments with HART, The isolation module is designed for transmitting the
PWM input signal to output isolated standard 4~20mA through output loop-powered .Meanwhile the module can offer a isolation
micro-power for the pre-devices. The module also has an integrated HART signal channel. according to the recommended solutions, it can
realize the Half duplex communication between the field and control area. which greatly reduce the wiring cost between the field and the
control area.
The module adopts unique electromagnetic isolation mode and high performance power feedback. The module achieves the function
of transmitting PWM signal to isolated standard 4~20mA accurately, which can match instruments analog input port(such as PLC , DCS ,
etc).
In addition, this module has small package (SIP9) and excellent temperature drift characteristics (at -40 ℃ ~ +85 ℃ operating
temperature range drift is less than 50PPM / ℃). This module can bear 2KVAC isolation voltage between the input and output.
