IL2302-B318-0000
by Beckhoff
The Beckhoff IL2302-B318-0000 coupler box unit from the IL Coupler Box Units series by Beckhoff provides a robust interface for industrial automation applications. Featuring 4 inputs + 4 outputs channels, it delivers versatile signal distribution and isolation in PROFIBUS networks. Designed for reliable operation on 24 V DC (-15%/+20%) rated load voltage, the unit supports a maximum output current of 0.5 A per channel, enabling efficient control of ohmic, inductive, and lamp loads. Its primary function is to isolate, condition, and relay digital signals between field devices and control systems, ensuring stable and precise data exchange.
Incorporating advanced technical specifications, the IL2302-B318-0000 draws a typical auxiliary supply current of 20 mA and features an input filter time of 3.0 ms to suppress noise and optimize signal integrity. Connections are handled via robust M12 screw type I/O connectors and an M8 female, 4-pin, A-coded downstream connector, while power feed is provided through an M8 male, 4-pin, A-coded connector. Each channel includes individual output short-circuit protection, and the sensor supply is short-circuit proof with a maximum supply current of 0.5 A. Signal thresholds conform to Signal Voltage 0: -3…+5 V and Signal Voltage 1: 11…30 V, fully complying with EN 61131-2, type 2 standards.
Built for demanding industrial environments, the IL2302-B318-0000 operates reliably across an operating temperature range of 0…+55°C and can be stored between -25…+85°C. Its durable polyamide housing and protected connectors ensure resilience against shock and vibration, aligning with EN 60068-2-6 and EN 60068-2-27. The module’s compliance with EN 61131-2, type 2 provides assurance of signal integrity and safety. By integrating this coupler box into automation systems, engineers benefit from simplified wiring, enhanced signal isolation, and improved system uptime in high-performance industrial applications.
