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

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
