Product Description:
EL1xxx | EtherCAT Terminals, digital input
The EtherCAT Terminals from the EL1xxx, ES1xxx and ELX1xxx series are intended for the acquisition of binary signals. Typically, these are mechanical contacts such as break contacts or make contacts, electronic sensors such as inductive proximity switches, optical sensors or other methods in order to generate a low/high signal in the sense of control technology. This signal is transmitted via EtherCAT to the higher-level automation device for further processing. The terminal variants differ by different signal thresholds, number of channels, connection options and/or input filter times. The portfolio is rounded off by additional functions such as XFC (timestamp/oversampling), safety or combined input/output terminals.
EL1918 | EtherCAT Terminal, 8-channel digital input, 24 V DC, TwinSAFE, TwinSAFE Logic
The EL1918 TwinSAFE component is a digital input terminal for sensors with potential-free contacts for 24 V DC. The EtherCAT terminal has eight fail-safe inputs, which are transmitted via FSoE to a TwinSAFE Logic-capable component.
The EL1918 has safety parameters to specifically adapt the functionality to the respective safety requirements. Thus, for example, test pulses can be configured with fine granularity for all eight channels in order to be able to connect as many types of sensors as possible.
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 EL1918:
For applications without integrated TwinSAFE Logic, the EL1918-2200 can be used.
