Product Description:

The 0RMSM1135.4G-EG is a networking module from B&R Automation that belongs to the 0RM GateManager Modules series. Designed as an industrial gateway, it provides a secure bridge between remote equipment and supervisory systems, allowing remote monitoring of controllers or panels without requiring on-site access. By combining wired Ethernet and optional cellular uplinks in a DIN-rail format, the product supports centralized device management while fitting into standard control cabinets used across manufacturing, process, and utility automation. It is suited for applications that need secure remote connectivity between field devices and higher-level networks.

At its core, the module runs on a ARM Cortex-A5 processor clocked at 563 MHz, giving it enough compute power for encryption, firewall inspection, and five device agent sessions. Network traffic enters through a shielded RJ45 port that follows the 10BASE-T/100BASE-TX physical layer. A separate SMA connector handles the single cellular uplink so remote sites can be reached when wired service is unavailable. Two digital inputs and two digital outputs allow alarms or resets to be triggered directly from the enclosure, keeping critical control pathways independent of the data network. Even during peak traffic, the unit draws only 5 W, which simplifies power budgeting in crowded panels, and the housing carries an IP20 protection class suitable for installation in ventilated electrical closets.

In control cabinets where space is at a premium, the module’s compact mechanics are an advantage. The weight is only 0.5 kg, and the enclosure footprint measures 97 mm in depth, 107 mm in height, and 32 mm in width, so multiple gateways can be lined up on a single DIN rail without exceeding common rail loading limits. These proportions also help maintain airflow around neighboring drives and PLCs while preserving clearance for surrounding cabinet components.
