Beckhoff EL1904 EtherCAT Terminal, 4-channel digital input, 24 V DC

The EL1904 TwinSAFE component is a digital input terminal for sensors with potential-free contacts for 24 V DC. It has four fail-safe inputs. The signals are transmitted via FSoE to a TwinSAFE Logic-capable component and can be used there to evaluate them in terms of safety. The EL1904 has safety parameters to adapt the functionality specifically to the respective safety-oriented requirements (e.g., 1-channel evaluation vs. 2-channel evaluation, testing of the individual channels). The safety parameters are not stored directly on the component, but are transmitted to the input terminal via a TwinSAFE Logic-capable component when the safety application is started. This simplifies service procedures, because the component can simply be replaced. The safety-relevant parameters are transferred to the new component when the safety application is restarted. Special features: 4 safe inputs cross-circuit detection 1-channel vs. 2-channel evaluation directly on the component testing of the channels can be activated individually https://www.beckhoff.com/en-en/support/download-finder/search-result/?download_group=35673106&download_item=35675115 https://www.beckhoff.com/en-en/products/automation/twinsafe/twinsafe-hardware/el1904.html?
