ECO-422-8 Return

 

 

ECO-422-8 is a changeover unit for RS-232/422. The changeover unit supports 8 changeover channels, and each channel has main & backup RS-232/422 inputs and 1 output. The changeover from main channel to backup channel is realized via Relay. Main channel supports loop-thru when power is off. 8 channels can be set to GPI1 group and GPI2 group via the DIP switch of its rear panel. Each group supports special changeover control button and GPI control interface, and the changeover mode can be selected via AUTO button of its front panel.  ECO-422-8 can also be controlled via PC on RS-232/422 port.

 

Featuring the function of GPI cascading, ECO-422-8 is convenient for users to expand the size of the changeover unit. Dual power supply unit design ensures the stability and reliability of the system.

 

ECO-422-8 is ideal for changeover between Main & Backup Control Systems in Broadcast Control System or in other occasions where RS-232/422 interface changeover is needed.
