eBay NEW Beckhoff EL1904 4-Channel Digital Input Terminal Twin Safe 24V DC In Box The EL1904 TwinSAFE assembly is a digital input terminal for the sensor with a potential free contact of 24 V DC.  It has four fail safe inputs. Signals are transmitted to components with TwinSAFE Logic function through FSoE and can be used to evaluate their security. EL1904 has safety parameters, which can be specially adjusted according to their respective safety requirements (for example, 1-channel evaluation and 2-channel evaluation, and testing of each channel). Security parameters are not directly stored on components, but are transferred to input terminals through components with TwinSAFE Logic function when starting security applications.  This simplifies the service program because components can be easily replaced.  When you restart a secure application, security related parameters are transferred to the new component.
