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.

Special features EL1918:

• 8 safe inputs

• integrated TwinSAFE Logic (functionality similar to the EL6910)

• up to 128 safe connections

• fine granular configuration of the test pulses of the individual channels

For applications without integrated TwinSAFE Logic, the EL1918-2200 can

be used.

Special features EL1918-2200:

• 8 safe inputs

• fine granular configuration of the test pulses of the individual channels

• TwinSAFE Logic not integrated

The safety-relevant parameters are transferred to the new component when

the safety application is restarted.

A further highlight of the EL1918 is the integration of the functionality of the

EL6910 TwinSAFE Logic. The EL1918 can also be used as a safety controller

at any time. In the default case, the EL1918 is a simple input terminal,

whose input signals are transmitted via FSoE to a TwinSAFE Logic-capable

component. It can be used directly as a safety controller in order to process

input signals directly in the terminal so as to forward only accumulated

information to a TwinSAFE Logic, or a complete safety application can be

implemented on the EL1918. The range of functions corresponds to that of

the EL6910. The only difference is the limitation of the number of possible

safe connections to 128. Apart from that, all the advantages of the new

generation of safety controllers can be used (see EL6910 customizing,

incremental download, analog value processing, etc.).

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
