BECKHOFF EP3162-0002 EtherCAT Box 2-Channel Analog Input Module

Description

Processing analog signals directly in harsh field environments is simplified with the EP3162-0002 EtherCAT Box. This IP67-rated decentralized module features two highly flexible, galvanically isolated analog inputs that are software-parameterizable for either voltage (-10/0 to +10 V) or current (-20/0/4 to +20 mA) signals on a per-channel basis. By executing analog-to-digital conversion directly at the sensor location, this module minimizes signal degradation over long wire runs, enabling clean 16-bit measurement resolution across distributed fieldbus networks.

The device features dual-channel isolation to eliminate ground loop issues, making it highly reliable in electrically noisy industrial applications. Connectivity is facilitated through robust, industry-standard M12 connectors for the sensor lines and M8 connectors for the EtherCAT fieldbus and power supply daisy-chaining. With integrated Distributed Clocks (DC) support, the module guarantees precise, synchronized data acquisition across large-scale industrial machinery.

Features

• Two single-ended, individually parameterizable analog input channels.
• Supports standard industrial signal ranges: -10 to +10 V, 0 to 10 V, -20 to +20 mA, 0 to 20 mA, and 4 to 20 mA.
• Complete galvanic isolation between individual input channels for high signal integrity.
• Fast analog-to-digital conversion time of approximately 100 microseconds per channel.
• High-precision 16-bit digital resolution (including sign).
• Distributed Clocks (DC) support for high-fidelity clock synchronization in time-critical tasks.
• Rugged IP65/66/67 physical housing for direct mounting outside of control cabinets.

Applications

• Decentralized process instrumentation and sensor monitoring in heavy industrial plants.
• Hydraulics and pneumatic system pressure, flow, and temperature tracking.
• Machine-mount data acquisition systems in automotive assembly and packaging lines.
• Test bench environments requiring high-speed, synchronized analog measurements.

Installation Guidelines

• Mounting: Screw the module directly onto flat machine surfaces using the integrated mounting holes. Ensure the mounting plane is grounded.
• Shielding: Use fully shielded M12 sensor cables and shielded M8 EtherCAT cabling to preserve signal integrity and prevent electromagnetic interference (EMI).
• Power Daisy Chaining: When utilizing the downstream M8 power output, verify that the total current draw of downstream modules does not exceed the maximum power bus capacity.
• Sealing: Unused M12 and M8 ports must be sealed with appropriate IP67 protection caps to maintain environmental integrity.
