ABB 3BSE025986R0401 S800 I/O System

ABB 3BSE025986R0401 S800 I/O System

DESCRIPTION

S800 I/O is a comprehensive, distributed  and modular process  I/O system that communicates with parent controllers over  industry-standard  field buses. Thanks to  its broad connectivity  it fits a wide range of  process controllers  from ABB and others. By permitting installation in the field, close  to sensors and actuators, S800 I/O reduces the installation  cost by reducing the  cost of cabling. And  thanks to features  such as “hot swap” of  modules, “on-line”  reconfiguration and  redundancy options,  it contributes to  keeping production –  and thereby profits –  up.
