3.2.1 The I/O construction kit is extended safely The integrated TwinSAFE safety solution is the logical continuation of the open, PC-based Beckhoff control philosophy. Due to their modularity and versatility, the TwinSAFE components fit seamlessly into the Beckhoff control system. The I/O components are available in the formats Bus Terminal, EtherCAT Terminal, EtherCAT plug-in module and EtherCAT Box. -
Page 18: The Fail-Safe Principle (Fail Stop)
The basic rule for a safety system such as TwinSAFE is that failure of a part, a system component or the overall system must never lead to a dangerous condition. CAUTION Safe state! The safe state of the TwinSAFE system is always the switched-off and de-energized state. Version: 2.0.0 EL2912 and EL2912-2200... -
Page 19: Product Description
Product description Product description EL2912 and EL2912-2200 The EL2912 is a safe output terminal with two fail-safe outputs, each with 2 A (24 V The EL2912 meets the requirements of the following standards: • EN 61508:2010 (SIL 3) • EN 62061:2005/A2:2015 (SIL CL 3) • EN ISO 13849-1:2015 (Cat. 4, PL e). The TwinSAFE terminal has the typical design of a 12 mm EtherCAT Terminal. The outputs use the voltage of the power contacts. -

Page 37: Fig. 15 Max. Cable Length
When connecting a single actuator via its own continuous cabling (or via a sheathed cable), the maximum permitted cable length is 100 m. The use of contact points, connectors or small wire cross-sections in the wiring reduces the maximum expansion. Cable routing Fig. 16: Cable routing EL2912 and EL2912-2200 Version: 2.0.0... - Page 38 The common routing of signals together with other clocked signals in a common cable also reduces the maximum propagation, since crosstalk of the signals can occur over long cable lengths and cause diagnostic messages.
