It can run in point-to-point or multi-drop configuration with up to 15 HART slave devices, and it allows two HART masters on the network. A selectable 250 Ω loop resistor is set by DIP switch, so the unit can be fitted without an external resistor where one is required.Configuration is carried out with the free HC_Tool utility over an RS-232 configuration port, and firmware can be updated through the same COM port. Fiber break detection and a built-in watchdog help with fault diagnosis, while 4 kV ESD protection and UL1577 isolation on the HART port support reliable installation. The unit mounts on a DIN rail and is rated for an operating temperature of -25 ~ +75 °C.ApplicationsCurrent measuringPetrochemical industryEnvironment monitoringTunnel monitoringMonitor systemsBuilding monitoring
