Product Description:
The IL2300-B510 is a coupler box manufactured by Beckhoff and belongs to the IL Coupler Box Units series. This unit serves as an interface that joins localized digital I/O points to a higher-level control system through Beckhoff’s IP-Link backplane. By providing both input and output channels in a sealed housing, it allows sensors and actuators on a machine frame to be wired directly at the point of use, reducing control-cabinet wiring and simplifying decentralized automation layouts.
The device is a Coupler Box with IP-Link, indicating that internal communication to the upstream Bus Coupler uses the IP-Link serial backplane instead of discrete wiring. Four separate sensor channels are available through its 4 digital inputs, and each channel can switch states independently to feed status information to the controller. Actuator control is handled by 4 digital outputs that deliver field-level power for solenoids or indicator lights. Communication is accomplished over the CAN physical layer using the CANopen protocol, so the box appears as a standard slave node in distributed I/O scans. Between the module and the IP-Link master, data is transferred at 2 Mbit/s, keeping cycle times short for motion or safety-related logic. An optical fiber extension interface allows longer distances without electrical noise coupling.
Mechanical integrity is provided by a housing molded from PA6 (polyamide), with the internal electronics fully encapsulated in polyurethane to resist vibration and moisture. External ingress protection is rated at IP65/66/67, allowing washdown or outdoor placement in any mounting orientation. Field wiring snaps into place with an 8 mm snap-on connector system, while two 2 x M3 mounting holes secure the unit to machine plates. Copper-zinc gold-plated contacts and nickel-plated brass metal parts maintain low contact resistance, and the module is not programmable, so all parameterization is handled by the host controller.
