Product Description

ARTU-KJ8 Series Remote Terminal Unit

General

ARTU distributed monitoring and control devices is a high-performance components used in intelligent power distribution, industrial automation, and other fields.Products include: remote control unit, remote signaling unit.It has a channel status light and a communication status light.It has two-way communication interface,one is used to set the general parameters
and commissioning,another is used to read and set the "four remote" value.Product's address and baud rate can be set by PC and local DIP switch.Products using the software and hardware "watchdog" technology to prevent freezing.
The user's Guide applies to ARTU distributed monitoring and control devices
