Description
For demanding safety-critical applications in automated environments, the BECKHOFF EK1960-0000 provides a highly integrated, stand-alone TwinSAFE Compact Controller. This specialized unit consolidates safety logic execution and dense physical I/O routing directly into one compact design. It functions as a flexible link unit between safe input and output signals, enabling immediate local processing while seamlessly interfacing with standard EtherCAT Terminal (ELxxxx) systems.
The controller incorporates 20 safe digital inputs and 24 safe digital outputs within a single housing, utilizing a space-saving 1-wire connection technology. Engineered to satisfy stringent global functional safety standards, the module processes complex logic instructions using the Safety over EtherCAT (FSoE) protocol, achieving extremely low cycle times down to approximately 1 ms. This makes it an ideal central controller for safety networks in complex machinery and processing systems.
Features
- Consolidated safety design housing 20 safe digital inputs (24 V DC) and 24 safe digital outputs (24 V DC, 2 A).
- Seamless communication integration via the TwinSAFE/Safety over EtherCAT (FSoE) protocol.
- Fast internal execution logic featuring typical cycle times of approximately 1 ms depending on project scope.
- High-capacity digital outputs supporting up to 2 A with a 50% simultaneity factor.
- Certified for use in high-risk applications up to SIL 3 (EN 61508:2010) and PL e, Category 4 (EN ISO 13849-1:2015).
- Highly reliable 1-wire connection technology to minimize installation space and control cabinet wiring.
Applications
- Emergency stop circuit monitoring and safety door interlocking.
- Optoelectronic protective devices (light curtains, laser scanners).
- Robotic cell protection and material handling safety zones.
- High-density machinery manufacturing and complex assembly systems.

Installation Guidelines
- Always mount the controller horizontally on a standard 35 mm DIN rail to maintain thermal specification parameters.
- Verify that the supply voltage matches the specified limits of the US (system power) and UP (peripheral power) circuits before commissioning.
- Implement proper ground and shielding practices on the RJ45 network cabling to protect logic circuits from electromagnetic interference.
- Install the module in an enclosure matching at least IP54 rating when operating in dusty or humid industrial environments, as the module itself is rated IP20.
