Modbus RTU/ASCII slave to HART master gateway with 2 HART ports
Tính năng
I-9720 is a Modbus RTU/ASCII slave to HART master gateway with two HART ports. It can be used in Windows / WinCE / Linux 9K series PAC for Modbus master to get HART device data easily. It provides adjustable HART loop power (27VDC) and loop resistor (250 ohm, 2W) to simplify HART network wiring. Free HG_Tool is used for module configuration and HART device data monitor quickly.
