Overview
Description
The SLG47011V HART Modem is a demonstration board that shows the implementation of the industrial HART protocol on a mixed-signal IC from Renesas. The board contains both logical parts - Host Device and Field Device - to respectively simulate the work of the master (controller) and the remote (sensor) device. For both parts, SLG47011V ICs are used as a modulator/demodulator front-end between the user interface (UART) and HART interface (FSK modulation).
Features
- HART physical layer and 4mA to 20mA current loop interfaces support
- HART modem is tested according to the HART protocol test specification (FSK Physical Layer Test Specification, HCF_TEST-2, Revision 2.2 document) (not a HART-certified device)
- Two separate devices connected through a communication line on a single PCB (Field device and Host device)
- Selectable power modes (Loop/External power selection for Field device), Internal/External current loop source selection. External analog input for a current loop. Loop current control
- Galvanic isolation for both Host and Field devices
