Description
Decentralized industrial environments require rugged, high-performance I/O routing directly at the machine interface. The BECKHOFF IP2041-B518 is an IP67-rated Fieldbus Box designed to distribute 8 digital output signals over a high-speed CANopen network. Operating at a nominal 24 V DC, this module offers robust switching capabilities, delivering up to 2 A per individual channel with short-circuit protection, making it ideal for commanding valves, actuators, and contactors directly in harsh environments without an electrical cabinet.
Equipped with an integrated T-connector for the CANopen bus line, the IP2041-B518 simplifies linear network topology by allowing incoming and outgoing fieldbus lines to be daisy-chained without additional external splitters. Its M8 connection interface ensures tight, vibration-resistant connections for digital signals, while its polyamide housing stands up to moisture, dust, and mechanical stress in demanding physical plants.
Features
- 8 independent 24 V DC digital outputs rated at 2 A per channel (12 A cumulative limit).
- Built-in CANopen physical interface via integrated M12 T-connector.
- Automatic baud rate detection from 10 kbaud up to 1 Mbaud.
- Short-circuit proof outputs with individual diagnostics.
- IP65/66/67 environmental protection for direct machine mounting.
- Standard M8 screw-type connection interfaces for reliable field signaling.
Applications
- Decentralized packaging machinery and sorting lines.
- Automobile assembly plants and robotic welding stations.
- Material handling conveyor lines.
- Pneumatic valve manifold control.

Installation Guidelines
- Mount the module directly to flat machinery frames using the 2 pre-molded mounting holes (3.5 mm diameter, compatible with M3 screws).
- Ensure all unused M8 and M12 interfaces are fitted with matching protective caps to maintain the integrity of the IP67 moisture seal.
- Verify that overall power consumption does not exceed the maximum aggregate limit of 12 A across all output channels.
- Observe standard shielding practices for the CANopen trunk line, using shielded copper cables designed for high-noise industrial sectors.
