Siemens N 148 Series Interface Module

This Interface module provides a Compact relay between control systems and field devices in automation environments. It is designed for integration into industrial process control setups requiring a 24V supply and compatibility with standard approval frameworks. The unit operates across typical indoor plant temperatures and is intended for DIN-rail mounting where space efficiency and straightforward electrical interfacing are priorities.

• Operates from 24V supply for direct control system compatibility
• Rated for continuous use between -5°C and +45°C for ambient stability
• Narrow 36mm width for high-density DIN-rail assemblies
• Low-profile 60mm depth for Compact cabinet layouts

• Suitable for signal interfacing in factory automation control racks
• Ideal for linking sensors and actuators in process control systems
• Used with PLC cabinets where approved modules are required
• Can be used for electrical isolation between subsystems in installations

It is developed to fit on DIN-rail profiles, enabling tool-free installation in standard control enclosures.

It is intended for indoor industrial environments operating within the specified ambient temperature range.

The device accepts a 24V supply voltage, allowing direct connection to common PLC and control system power rails without intermediate converters.
