Information About EL1918
The EL1918 is part of Beckhoff’s TwinSAFE safety series and is designed as an eight-channel safety input terminal with configurable operating parameters. It is built in a compact HD-style housing with LED indicators and supports 1- or 2-wire connection technology for diverse safety sensor types. The module integrates seamlessly into TwinSAFE architectures and can transmit safety-relevant signals via FSoE to controllers such as EL6910-based systems. Typical applications include emergency stop circuits, light curtains, safety switches, and other SIL-oriented safety devices requiring configurable test pulses and safe digital input processing.
Key Features
- Eight Fail-Safe Inputs: Supports safe digital signal acquisition for various certified safety sensors.
- TwinSAFE / FSoE Communication: Ensures secure transmission of safety data to TwinSAFE Logic devices.
- Integrated Safety Logic: Can act as a safety controller with functionality similar to the EL6910.
- Highly Configurable Test Pulses: Fine-granular pulse configuration for all eight channels.
- HD Housing Design: Slim 12 mm terminal width for dense I/O installations.
- DIN-Rail Mounting: Compatible with standard 35 mm EN 60715 DIN rails for easy installation.
- LED Status Indicators: Provides clear visual status feedback for each channel.
- Service-Friendly Parameter Handling: Safety parameters are stored externally, allowing quick terminal replacement.
The EL1918 delivers the reliability and precision required for advanced machine safety and secure EtherCAT-based automation.
