RS-485 I/O Expansion Unit Catalog
■The RU-87Pn series RS-485 remote I/O expansion unit is designed to acquire and control remote I/O through RS-485 connections. It comprises
▲A CPU module with none-volatile memory to backup/restore I/O module configurations; LED indicators to diagnose the I/O module; and a RS-485 port for 1.2 Km long distance communication.
▲A power module
▲A backplane with a number of I/O slots for flexible I/O configuration.
▲With its patent-pending technologies, namely auto configuration and hot swap, it saves lots of labor on the set up and maintenance of the automation systems. Reliable 3-piece construction enables users to hot swap modules during operation, without rewiring. All I/O module data are backed up in the non-volatile memory of the RU-87Pn. After hot-swapping a module, all settings are automatically loaded to recover.
▲Furthermore, with the RS-485 network communication interface and more than 30 I/O modules for choice, users can apply the unit to nearly any automation system.
