Description

The BECKHOFF ER8309-1022 is a multi-functional EtherCAT Box designed for direct field installation in demanding industrial environments. By integrating a versatile combination of digital, analog, and specialized current-controlled pulse-width modulation (PWMi) channels into a single, compact unit, this module enables decentralized physical signal acquisition and control without requiring an electrical control cabinet.

The unit establishes direct communication with an EtherCAT industrial network through shielded M8 screw-type connectors, maintaining signal integrity and high transmission rates. Its specialized architecture combines digital inputs/outputs, standard current analog inputs, an analog output, and a high-frequency PWMi output to handle complex field devices like proportional valves, sensors, and actuators from a single decentralized point.

Features

• Highly integrated multi-signal processing, minimizing the requirement for separate specialized I/O boxes.
• 8 digital channels that are individually configurable as either inputs or outputs.
• 2 single-ended analog inputs supporting standard 0 to 20 mA or 4 to 20 mA operational ranges with 12-bit resolution.
• 1 single-ended analog output supporting 0 to 20 mA or 4 to 20 mA signals with 12-bit resolution.
• 1 current-controlled PWMi output capable of delivering up to 1.2 A at a maximum frequency of 30 kHz, optimal for proportional valve applications.
• Physical environmental protection rating of IP65, IP66, and IP67 when fully connected and mated.
• Dedicated sensor supply sourced from the control voltage (Us) and actuator/load supply sourced from the auxiliary voltage (Up).

Applications

• Decentralized machine mounting and remote field-level signal acquisition.
• Hydraulic and pneumatic system control utilizing current-controlled proportional valves.
• Process monitoring involving analog pressure, flow, and temperature transmitters.
• Material handling systems and machinery operating in wet, dusty, or high-vibration conditions.

Installation Guidelines

1. Verify that the physical part number on the unit matches your system configuration requirements.
2. Ensure all power sources, including control voltage (Us) and auxiliary load voltage (Up), are completely de-energized before mounting or connecting.
3. Mount the EtherCAT Box securely onto a flat machine surface using appropriate fastening screws. Ensure the installation position aligns with your system drainage and cable routing plans.
4. Connect the incoming and outgoing EtherCAT cables to the M8 communication sockets. Hand-tighten the screw collars to ensure proper sealing.
5. Wire the sensors, actuators, and analog connections to the respective M12 sockets. Use shielded cables where necessary, especially for analog input/output and PWMi channels, to prevent electromagnetic interference.
6. Ensure all unused M8 and M12 sockets are sealed with protective caps to maintain the IP65/66/67 environmental rating.
7. Apply Us and Up voltages, check status LEDs for correct system boot, and proceed with TwinCAT system configuration and scan.
