Siemens 39SAMCAN APACS+ CAN Communication Module Industrial Interface

Product Description

Overview

The Siemens 39SAMCAN is a high-performance communication module designed for the APACS+ / Quadlog automation series. It serves as a gateway between control modules and decentralized field devices using the CANbus protocol, enabling seamless integration of sensors, drives, and third-party hardware into industrial control systems. Its modular, rack-mounted design allows flexible deployment across complex plant operations.

Product Description

The 39SAMCAN acts as a protocol translator and high-speed interface for CAN-based networks, translating internal control data into CAN messages. It is commonly applied in automotive manufacturing, mobile machinery, and precision motion control systems. The module supports both standard and extended CAN frames and integrates directly with Siemens APACS+ racks and DIN-sized backplanes.
