Overview Manuals Specifications Application Diagnostics & Protection Installation

Features:

  • Enables connection of Expansion Units (EUs) to the Central Controller (CC) via RS-485 up to 600 meters (1,969 feet) without signal degradation
  • Operates across multiple baud rates from 9.6 kbps to 187.5 kbps, allowing system tuning for speed or cable length
  • Features a wide storage temperature range and a robust physical form factor suitable for challenging environmental conditions
In the world of industrial automation, large factories and processing plants create a significant challenge: physical distance. Sensors and actuators located hundreds of meters from the main control room would traditionally require massive, expensive bundles of cable running back to a central point. The 6ES5304-3UB11 directly solves this problem by acting as the master interface for a distributed I/O network. Designed specifically for the S5 series (including S5-135U and S5-155U systems), this IM304 module allows a single Central Controller (CC) to communicate reliably with up to 4 Expansion Units (EUs) placed directly in the field, as long as they are within 600 meters.

The ability to communicate over long distances must be balanced against the speed of data transmission, as the physical properties of copper cables cause higher signal degradation at faster speeds. The 6ES5304-3UB11 provides crucial flexibility by supporting a range of standard RS-485 baud rates, including 9.6 kbps, 19.2 kbps, 93.75 kbps, and up to 187.5 kbps. This allows system integrators to make a key engineering trade-off. For a maximally distant expansion rack at the full 600 meters, a conservative lower baud rate like 9.6 kbps could be selected to ensure ultra-reliable, error-free data exchange.

Industrial control is not an office job; components are frequently subjected to temperature extremes, vibration, dust, and electrical noise. The 6ES5304-3UB11 is engineered to withstand these conditions, ensuring high system uptime in demanding applications like steel mills, offshore platforms, and mining operations. It features an IP20 protection rating, meaning the module's body is protected against solid objects greater than 12mm, making it safe for installation in standard control cabinets. More critically, the module boasts an exceptionally wide storage temperature range from -40°C to +70°C.

The 6ES5304-3UB11 Siemens Interface Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

General

  • Manufacturer Siemens
  • Model 6ES5304-3UB11
  • Condition New Original ready stock
  • Product Family 6ES5374-1KH21,6ES5526-3LG0,6ES5535-3LB12
Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
  • Distributed System Expansion: Connects remote I/O sub-racks (Expansion Units running an IM 314 module) back to the main chassis, removing the requirement to keep all I/O cards within the primary control cabinet.
  • High-Availability & Fault-Tolerant Systems: Acts as a hardware coupling module to interconnect central processing controllers inside redundant fault-tolerant PLCs.
  • Red FAULT LED Indication: Features a prominent front-panel physical FAULT LED indicator that immediately illuminates if bus crosstalk drops or a cable connection breaks.
  • Hardware Connection Monitoring: Continuously scans the physical connection layer to the remote IM 314 units. If line continuity is severed or a remote rack loses input power, the module flags a line error to the host CPU.
  • Timeout Interrupt Handling: Automatically triggers a time-out or peripheral fault organization block (e.g., OB 22 or OB 32 in STEP 5) inside the master CPU if communication frames do not complete safely within designated cycle ticks.
  • Galvanic Protection: Employs ruggedized isolation barriers across the serial interface connections, insulating the internal S5 backplane logic from ground loops or unexpected electrical surges originating down the 600m cable path.
  • Power Shutdown: Turn off the power supply on the central rack before handling. Never hot-swap an S5 module.
  • Rack Placement: Insert the IM 304 module into the dedicated interface slot of the S5 Central Unit / Main Chassis.
  • Cable Interconnection: Connect the specialized, shielded S5 interconnecting cable to the front port of the module, routing it out to the remote expansion chassis. Ensure the connector screws are tightened to establish a reliable shield ground.
Description
The 6ES5304-3UB11 is an IM 304 interface module designed for installation in the main unit of Siemens SIMATIC S5 automation systems. Its primary function is to enable decentralized I/O configurations, allowing remote input/output modules to be placed at significant distances from the central controller while maintaining reliable and deterministic communication. 

The 6ES5304-3UB11 supports a maximum connection length of up to 600 meters (approximately 1,968 feet) between the Electronics Device (ED) at the remote site and the Central Device (CD) located in the main control rack. This extended distance capability eliminates the need for multiple intermediary controllers or complex signal repeaters, simplifying system architecture and reducing overall hardware costs. 

By enabling this decentralized architecture, the 6ES5304-3UB11 significantly reduces field wiring requirements. Instead of running hundreds of individual sensor and actuator wires all the way back to a central cabinet, installers can place local I/O stations near the machinery they serve.

Technical notes
The 6ES5304-3UB11 is a Siemens SIMATIC S5 IM304 interface module enabling distributed I/O configurations. Operating on 5V DC, it connects the Central Controller (CC) to Expansion Units (EUs) over RS-485 up to 600 meters. It supports 9.6 to 187.5 kbps data rates, is certified for harsh environments (UL, RoHS), and is a legacy part, discontinued for new projects.
