Product Description

The KL1904 compact terminal by Beckhoff offers superior safety and performance with the KL Analog Input Series. It provides 4 inputs based on 2-wire connection technology for an error-free and efficient input system to cover a broad range of applications. It supports communication via high-speed secure data exchange with an enhancement in system safety through TwinSAFE/Safety over EtherCAT. Its typical response time of 4 ms makes it possible to read and write inputs to the K-bus at high speed, which is often crucial in many safety-related processes.

The KL1904 compact terminal shows its very good safety standards by meeting and even exceeding the ones for DIN EN ISO 13849-1:2008 (Cat. 4, PL e) and for EN 61508:2010 (SIL 3) for a very reliable application. The fault response time is smaller than or equal to the watchdog time, while the terminal can be parameterized in order to meet system requirements. In fact, its current consumption from the K-bus of 48 mA made it an energy-efficient option for different installations. The KL1904 is a horizontal installation that fits perfectly in a wide system configuration allowing for flexibility in location.

With its polycarbonate housing and signal LEDs, the KL1904 terminal has a very lightweight weight of approximately 50 g and can be fitted into compact design structures at 12 mm x 100 mm x 68 mm. Its protection rating is IP20, making it a good choice for industrial environments; the ATEX and IECEx markings confirm suitability for potentially explosive atmospheres. Moreover, the KL1904 offers a sturdy, reliable, and safe input solution for demanding automation environments while maintaining high performance even when stringent safety requirements have to be met.
