Key Specification
Core Features & Advantages
-
Essential and Mandatory for Any EtherCAT Station: The module's standout feature is that it is not optional for a correctly functioning EtherCAT system. Every I/O station connected via an EK1100 EtherCAT Coupler must be physically terminated on the right-hand side with an EL9011 end cover to protect the E‑bus and signal the end of the station to the system .
-
Simple Passive Design with High Reliability: As it contains no electronic components, this terminal has an extremely low failure rate and adds a mere 5 mm to the width of the station . Its sole purpose is to provide mechanical and electrical protection to the exposed contacts of the preceding terminal.
-
Robust and Tested for Industrial Environments: Designed for reliability, this end cover operates over a wide -25°C to +60°C temperature range and features CE, UL, and ATEX approvals for use in potentially explosive atmospheres .
Typical Applications
The EL9011 is used as a standard system component in all EtherCAT I/O stations where it provides protection for the communication bus. Its applications include:
-
EtherCAT I/O Stations: Used to terminate the bus in all Beckhoff installations, ensuring the integrity of the E‑bus .
-
Machine & Control Cabinets: Fitted as the final component in a row of I/O terminals to protect against dust and accidental contact.
FAQ
Q1: What is the purpose of this end cap?
The EL9011 end cap is used to terminate an EtherCAT station on the right-hand end. It covers the exposed E-bus contacts on the last terminal, protecting them from contamination and preventing communication errors. It is an essential component for every EK1100 EtherCAT station .
Q2: Is the EL9011 required for every EtherCAT station?
Yes. Every bus station must be physically terminated on the right-hand side with an end cap such as the EL9011. This is mandatory for proper system operation .
Q3: Does the EL9011 require any configuration?
No. This is a passive terminal that contains no electronic components, so no address or configuration settings are required in TwinCAT System Manager .
Q4: What is the weight of this part?
The EL9011 is quite lightweight, weighing approximately 8 to 10 g .
Q5: Does the EL9011 carry any electrical current?
No. The EL9011 is a purely mechanical component; it is a passive end cap and does not carry electrical current .
Q6: What certifications does this module hold?
The EL9011 carries CE, CCC, UL, ATEX, and IECEx certifications. The ATEX marking is II 3 G Ex ec IIC T4 Gc .
Q7: What is the operating temperature range of this module?
The operating temperature range is -25°C to +60°C, with a storage temperature range of -40°C to +85°C .
Q8: Can I use the EL9011 with any EtherCAT Terminal?
Yes. The EL9011 is compatible with all EtherCAT Terminals and can be mounted side-by-side regardless of whether the terminals have power contacts .
