STBACO1225K

The Schneider Electric STBACO1225K is a 2-channel, isolated analog voltage output module from the Advantys STB distributed I/O system. This module is designed to generate precise 0-10V or ±10V DC control signals for driving field actuators such as proportional valves, variable speed drives, or process controllers. It features channel-to-channel and channel-to-bus isolation for enhanced noise immunity and signal integrity in industrial automation environments.
