This product is now discontinued, but details are still available in our 'Legacy Products' section for information only.

Enable the remote power management of 8 devices over the Internet, Intranet or locally through an RS232 terminal connection.

The M8 Master is a power distribution and control unit with a built-in web server, Ethernet port and serial RS232 connection. It enables the user to control the power supply (turn on/off or restart), of up to 8 power sockets either remotely through a network, or locally through its serial RS232 connection. The number of controlled sockets can be increased to 40 by connecting up to four S8 (Slave) units using one IP address (total load 100 A / 230 V).

Product Features

Two password levels plus various administrator/user rights and security masks 

Two separate power inputs improve security and increase total current load (20 A / 230 V)

Twin mode controls a pair of power outlets at once (intended for servers with redundant power supplies)

Configuration functions are performed using ePS-Finder, a convenient tool for discovering, configuring and setting the IP address of ePowerSwitch devices on your network

Restart delay can be chosen between 5 and 60 seconds between off/on for activity at all power outlets
