Product Description

In industrial automation systems made especially for safety-critical applications, the Beckhoff EL1918 is a crucial part. This device is an 8-channel digital input terminal for the EL EtherCAT Terminal series. Compatibility with a variety of sensors and actuators is ensured by its operation on a 24 V DC power supply, which is a common voltage in industrial control systems. The "digital" aspect of the input means that it perceives signals as distinct on/off states, which makes it perfect for identifying things like when a limit switch is triggered or an item is present or absent. Integration of the EL1918 with Beckhoff's safety technology, TwinSAFE, is one of its most notable characteristics. TwinSAFE ensures excellent integrity and responsiveness by using the "black channel" approach, which transmits safety-related data on the same EtherCAT network as regular communication data. Internal safety-related logic operations may be carried out by the terminal thanks to its support for TwinSAFE Logic. In crucial circumstances, this feature allows for quicker response times and less strain on the central controller. Because the EL1918 supports up to 128 secure connections, it can manage intricate safety configurations with a large number of sensors and actuators.

Dependability and safety are given top priority in the EL1918's design. The EN ISO 13849-1:2015 safety standard (Cat. 4, PL e) certifies that it satisfies strict performance level and fault tolerance standards. According to this specification, the device is appropriate for uses such as emergency stop systems and hazardous area protection where a high degree of safety is crucial. Additionally, each channel may have a different set of test pulses configured by the terminal. By enabling users to customize the device to certain sensor types and operational needs, this feature improves diagnostic capabilities and guarantees dependable operation. The EL1918's ability to identify and respond to problems within a user-defined period is further enhanced by the "≤ watchdog time (parameterizable)" fault response time specification.

With its small size and low weight (around 50 g), the EL1918 is a good choice for applications that need limited space. The cabinet layout and design are made more flexible by its horizontal installation position. A basic degree of protection for industrial settings is provided by the device's IP20 protection classification, which shields it from solid objects bigger than 12 mm, such as fingers. With compatibility for both 1- and 2-wire connection technologies, the terminal offers versatility in integrating sensors. Wake Industrial provides clients with peace of mind and a guarantee of product quality by offering a one-year warranty on the EL1918.
