Description
Designed for decentralized automation setups, the Beckhoff EP1518-0002 serves as an IP67-rated EtherCAT Box that integrates eight digital inputs into a rugged, cabinet-free housing. This compact module is optimized for direct machine mounting, eliminating the need for protective enclosures. Two of the eight inputs are highly versatile, supporting configuration as 32-bit up/down counters to handle pulse processing. The module fully integrates with EtherCAT networks, using Distributed Clocks (DC) to ensure high-precision temporal synchronization across the plant floor.
Features
-
Digital Inputs: 8 digital inputs with adjustable filter times from 0 to 100 ms to eliminate signal noise.

Installation Guidelines
To ensure trouble-free operation and maintain the rated IP67 protection, observe the following field installation guidelines:
-
Torque Requirements: All M8 and M12 connectors must be tightened to their specified torque values to ensure an airtight, moisture-proof seal. Unused sockets must be sealed with protective caps.
-
Grounding and Shielding: Ensure the EtherCAT Box is securely mounted to a grounded metallic surface or bracket. Use shielded Ethernet cables with proper termination at the M8 bus connectors.
-
Cable Routing: Avoid routing signal and sensor lines adjacent to high-power motor cables or variable frequency drive (VFD) wiring to prevent electromagnetic interference.
-
Power Distribution: Respect the maximum current carrying capacities of the M8 power connectors when daisy-chaining modules to avoid voltage drops across the segment.
