Product Description

The KL6904-0000 from Beckhoff is an important module in the KL Analog Input Series. It has a design as an output unit link unit for safe input and output signals. The module uses 2-wire connection technology, which makes it compatible and easy to be integrated in already existing systems. With 4 outputs, this module will work efficiently on several applications, the output current being 0.5 A (with a minimum of 20 mA), thus providing reliable output for optimum performance.

Equipped with the TwinSAFE/Safety over EtherCAT protocol, the KL6904-0000 ensures highly superior safety communication in automated environments. Its fault response time is parameterizable to be less than or equal to the watchdog time and, thus, flexible with regards to safety management. The current consumption of the module on power contacts is dependent on load, with a maximum being 250 mA from the K-bus, which means that the module does not draw a lot of power from the K-bus at all.

It has a horizontal installation position and is made of strong polycarbonate housing, weighing approximately 100 g. It is used for safety critical applications in which it fulfills the requirements of high standards like DIN EN ISO 13849-1:2008 (Category 4, Performance Level e) and EN 61508:2010 (SIL 3), hence making it very useful for securing major applications. On top of that, the module has a protection rating of IP20, making it highly reliable for its use in any kind of operational condition. The KL6904-0000 is ATEX and IECEx approved, so safe for use in potentially explosive atmospheres with Ex marking II 3 G Ex ec IIC T4 Gc. Compact dimensions of 24 mm x 100 mm x 68 mm allow for ideal installations in restricted spaces within new and modern automation systems.
