Product description

INTERBUS ST digital output modules for AC voltages

The digital INTERBUS output modules are designed for the connection of digital actuators, such as electromechanical valves, contactors or lamps.

In addition to the standard IB ST 24 BDO modules, the range is rounded off by modules with extended functionality.

The scope of functions provided by the standard models covers the majority of applications. On top of this, several modules provide additional electronic functions, such as:

- Output channels in up to four electrically isolated groups

- Separate electronic short-circuit protection for each output channel

- Higher output current

which are needed in individual applications.

All the typical advantages of INTERBUS-ST handling, such as multi-wire connection methods and plug-in electronics are provided by both product lines.
