Beckhoff IL2301 B310-0000 Profi-bus Coupler Box

Beckhoff IL2301-B310-0000 Coupler Box is a PROFIBUS fieldbus interface module that provides 4 digital inputs and 4 digital outputs for 24 V DC devices. It connects to a PROFIBUS DP network via a 1 x M12 socket, 5-pin, B-coded, enabling reliable communication between the bus and local I/O. This compact coupler, part of Beckhoff’s IL23xx family, delivers a fast 3 ms response time and supports a maximum of 0.5 A per output channel, making it suitable for discrete control tasks in automated systems. The unit is powered from a 24 V DC supply and wires to a 24 V logic level across its four input and four output channels. Typical applications include distributing digital I/O to sensors and actuators across machinery on factory floors, such as packaging lines or automated assembly cells, where compact PROFIBUS connectivity and robust 24 V signaling are required.
