Don’t let the simple looks of the Rail 350 fool you, this is a powerful, feature rich multifunction meter. The Rail 350’s ‘Right First Time’ setup includes the Auto-rotation functionality for CTs which may be installed incorrectly. This effort to minimize and correct any installation issues, married to the 5 year warranty and extensive data sets available via the communication options makes this the perfect system meter for any sub-metering roll-out. Standard feature on the Rail 350 is 2 pulse outputs, which can be configured for kWh and kvarh. To aid with installation and commissioning the meter offers a pulse test function to simulate pulses without any load being measured, allowing installation engineers to check cabling is complete. Standard communications are RS485 Modbus, however the Rail 350 is available with a range of powerful IP communications options MODBUS TCP and other TCP/IP protocols such as HTTP, FTP, TFTP, SNMP. The various TCP/IP protocols make this the ideal meter to interface directly with energy management software and building control solutions, without the need for data loggers or concentrators. The web pages on the IP enabled Rail 350 allows the user to view important instantaneous values and access the setup pages should the need arise to change any of the parameters.
