2736628 PHOENIX Inline Fieldline Extension Module
Product Dimensions:
Product Description (Detailed Explanation)
The 2736628 (Technical designation: FLS IB M12 DI 8 M12) is an IP67-rated device that functions as a remote I/O node for INTERBUS networks. It features 8 digital inputs, typically used for connecting proximity sensors, limit switches, or push-buttons using standard M12 circular connectors.
The “Fieldline” design philosophy focuses on “cabinet-free” installation. The housing is ruggedized to withstand water, dust, and mechanical stress, making it a reliable choice for modular machine building where I/O points are distributed across large areas.

Product Advantages (Key Benefits)
-
Cabinet-Free Installation: The IP67 rating allows the module to be mounted directly on the machine frame, drastically reducing wiring costs and enclosure size.
-
Fast Installation: Utilizing M12 plug-and-play connectors eliminates the need for terminal blocks and individual wire stripping, reducing commissioning time.
-
Comprehensive Diagnostics: Each input features an LED indicator for status, and the module provides bus-level diagnostics to identify power failures or network interruptions quickly.
-
Mechanical Durability: The housing is resistant to vibrations, shocks, and common industrial lubricants, ensuring a long service life in harsh environments.
-
Modular Scalability: Easily integrates into existing INTERBUS loops, allowing for quick expansion of field sensors.
Precautions (Important Notes)
-
INTERBUS Topology: Ensure that the total cable length and number of devices in the INTERBUS ring do not exceed the specified system limits to maintain signal integrity.
-
Connector Tightening: M12 connectors must be tightened to the recommended torque (typically 0.4 Nm) to maintain the IP67 seal.
-
Unused Ports: All unused M12 sockets must be covered with protective caps to prevent moisture and dust from entering the electronics.
-
Sensor Power: Monitor the total sensor current draw. The module distributes 24V DC to the sensors; exceeding the maximum supply current can trigger protective shutdowns.
Product Applications (Typical Use Cases)
-
Conveyor Systems: Distributed sensing for pallet detection, sorting gates, and emergency stop monitoring across large logistics centers.
-
Automotive Production Lines: Connecting proximity sensors on robotic welding cells where space for control cabinets is limited.
-
Packaging Machinery: Modular I/O for decentralized control of capping, labeling, and filling stations.
-
Machine Tooling: Mounting directly on CNC frames to collect data from limit switches and tool presence sensors.
