Product Description:

The Beckhoff KL2641 Bus Terminal supports manual and automatic operation modes. The unit is designed to work with 230 V AC power. It offers a maximum output current of 16 A and switching capacity up to 5 kVA. The terminal is designed for universal switching applications.

The KL2641 Bus Terminal from the KL Series is equipped with a single normally open (NO) relay contact designed for direct switching of mains voltages. It can handle maximum switching voltages up to 440 V AC. The relay is capable of switching currents up to 10 A that is suitable for high demand industrial loads. The terminal ensures galvanic isolation between the field side and the bus system that enhances operational safety. The maximum switching current is 16 A AC and it supports ohmic, inductive and lamp loads. The unit features a typical current consumption of 65 mA plus load on power contacts and 5 mA on the K-bus. The contact material is AgSnO₂. The terminal includes two inputs and two outputs in the process image for status and control. The relay can perform up to 1,000,000 mechanical operating cycles. It supports manual switching when the controller is unavailable.

The KL2641 bus terminal offers a bi-stable relay contact for stable switching without continuous coil power. It supports a maximum starting current of 16 A for electronic ballast tests. The module weight is approximately 110 g. The relay coil control is interrupted during manual operation. The model is ideal for applications where both manual and automatic switching are necessary. The bus terminal displays operating mode clearly and provides robust switching capacity for industrial and commercial uses. Order this bus terminal today from Wake Industrial.
