BECKHOFF - EL1904 - EtherCAT TwinSAFE 4-Channel Digital Input Terminal

BECKHOFF – EL1904-0000 – EtherCAT TwinSAFE 4-Channel Digital Input Terminal

Main Category: Electronics | Sub-Category: Electronic Cards | Status: New Original Components
BECKHOFF Part Number: EL19040000 | ICDC Part Number: ICDC-000589

Description:

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.
