## Summary description

Expansion module KL04NSB by SALUS designed to connect to the KL08NSB rail. Provides additional I/O extension for compatible SALUS control rails. Intended for mounting on DIN-rail and integration into building automation or heating control systems to increase channel capacity and expand system functionality.

## Long description

The SALUS KL04NSB expansion module is designed to extend the input/output capacity of compatible SALUS control rails by adding four additional channels. Intended for mounting on standard DIN-rail, this compact module connects directly to the KL08NSB rail to increase system capacity and enable additional sensor or actuator connections in building automation and heating control installations. The module is suitable for integration where incremental expansion of control points is required without replacing the main rail.
Advantages
The KL04NSB provides a straightforward way to grow an existing SALUS KL08NSB rail installation by adding extra I/O channels without reconfiguring the entire system. Its DIN-rail compatible form factor simplifies installation in electrical cabinets and control panels, while direct compatibility with SALUS rails ensures consistent electrical and communication behavior. The compact design reduces space requirements and helps maintain organized wiring inside distribution enclosures.

How to use
Mount the KL04NSB module on a standard 35 mm DIN-rail near the existing KL08NSB rail and establish the mechanical and electrical connection according to the SALUS rail alignment.
