Beckhoff KL6904 Bus Terminal Bus Terminal
TwinSAFE Logic Bus Terminal with 4 digital outputs 24V DC, 0.5 A, Safety standard: DIN EN ISO 13849-1:2008 (Cat 4, PL e) and IEC 61508:2010 (SIL 3)
TwinSAFE enables networks with up to 1,024 TwinSAFE devices.
The KL6904 TwinSAFE Logic Bus Terminal can establish 15 connections (TwinSAFE connections).
Multiple Logic Terminals are cascadable within a network.
The Bus Terminal features certified safety function blocks, which are configured according to the application to be realised.
Functions such as emergency stop, safety door monitoring, etc. can thus easily be selected and linked.
All blocks can be freely connected among each other and are complemented by operators such as AND, OR, etc.
The required functions are configured via the TwinCAT System Manager and loaded into the KL6904 Logic Terminal via the fieldbus.
The TwinSAFE logic terminal has four safe, local outputs, so that safety applications can be realised with only two components (KL1904 and KL6904).
The KL6904 is suitable for applications up to DIN EN ISO 13849-1:2008 (Cat 4, PL e) and IEC 61508:2010 (SIL 3).
