Information About EL4122
The EL4122 belongs to Beckhoff’s advanced EL4xxx series of EtherCAT analog output terminals, engineered for precise current signal generation in automation systems. Each of the two channels delivers 4–20 mA current signals with 16-bit resolution, allowing fine control of actuators, valves, and analog devices. Its output stages are powered by the 24 V DC supply and share a common ground potential, simplifying wiring while maintaining high electrical integrity. The terminal features distributed clock capability for synchronization with other EtherCAT devices, ensuring deterministic signal timing. Built-in short-circuit protection and a configurable watchdog function further enhance safety and reliability. With its robust design and compliance with industry EMC standards, the EL4122 is suited for demanding process control, instrumentation, and machine automation environments.
Key Features:
- Dual Analog Outputs: Two 4–20 mA output channels provide independent current control for analog actuators and process loops.
- High Signal Resolution: 16-bit digital-to-analog conversion ensures precise and smooth current generation.
- Electrical Isolation: 500 V isolation between E-bus and signal voltage protects connected devices and prevents interference.
- Distributed Clock Synchronization: Enables microsecond-level synchronization with other EtherCAT components for time-critical operations.
- Short-Circuit Protection: Safeguards outputs against overload and wiring faults for long-term durability.
- Fast Output Performance: Delivers up to 15,000 samples per second for responsive analog control.
- Parameterizable Watchdog: Monitors output activity and automatically triggers user-defined safety states in case of system faults.
- Compact Modular Design: Fits seamlessly into EtherCAT systems, allowing flexible and scalable I/O configurations.
- EMC-Compliant Reliability: Meets EN 61000-6-2/6-4 standards for electromagnetic compatibility in industrial environments.
- Wide Operating Range: Performs consistently from -25°C to +55°C and up to 95% humidity for industrial use.
The EL4122 delivers the reliability and precision required for current-based control, process automation, and instrumentation tasks in EtherCAT-based systems.
