Product Overview
The Beckhoff KL2134 is a high-performance digital output terminal designed for integration into Beckhoff’s modular I/O system,specifically within the KL-series EtherCAT Box or CX-series control platforms.This compact and reliable module provides four independent channels of transistor-based digital outputs,making it ideal for controlling low-power actuators,relays,solenoids,indicator lights,and other 24VDC field devices in industrial automation environments.As a key component of Beckhoff’s distributed I/O architecture,the Beckhoff KL2134 enables efficient signal transmission from the PLC controller to the machine level,reducing cabinet space and wiring complexity.
Engineered for robustness and precision,the Beckhoff KL2134 supports sinking output configuration(NPN),where the module provides the ground path for the load.Each output channel is capable of switching up to 0.5 A,with short-circuit and overload protection built-in to ensure system safety and longevity.The module communicates via the high-speed EtherCAT fieldbus,enabling deterministic data exchange with cycle times as low as 100µs,which is essential for time-critical applications.The Beckhoff KL2134 is DIN rail mounted,features LED status indicators for each channel,and operates within a wide temperature range,making it suitable for harsh industrial conditions.Whether used in packaging machinery,material handling systems,or process automation,the Beckhoff KL2134 delivers consistent performance and seamless integration.

Installation and Maintenance
Pre-installation preparation:Before installing the Beckhoff KL2134,ensure the DIN rail is securely mounted and free of debris.Verify that the power supply matches the 24 VDC nominal voltage and is properly grounded.Check the load requirements to ensure they do not exceed 0.5 A per channel.Plan the terminal block layout to minimize wire length and avoid high-voltage or high-noise lines near the signal cables.Confirm that the EtherCAT network topology supports the addition of the Beckhoff KL2134 and that the master controller is configured accordingly.
Maintenance recommendations:Periodically inspect the Beckhoff KL2134 for signs of overheating,discoloration,or loose connections.Clean the module surface with a dry,lint-free cloth to remove dust accumulation.Monitor the LED indicators during operation to verify correct output activation and detect any fault conditions.If a channel fails,check the connected load for short circuits or overcurrent conditions before replacing the module.Avoid exposing the Beckhoff KL2134 to moisture or corrosive atmospheres,and ensure the control cabinet maintains adequate ventilation.
