KL1819
by Beckhoff
The KL1819 module by Beckhoff is a precision-engineered input device within the renowned KL Analog Input Modules series, designed for robust industrial automation environments. This compact module provides 16 digital input channels with a nominal voltage of 24 V DC and a tolerance range of -15%/+20%. It employs advanced 1-wire connection technology for streamlined wiring and integration into control cabinets. At just approx. 60 g in weight, the KL1819 offers a high density of inputs without imposing significant mechanical load on DIN-rail installations. Compliance with EN 61131-2, type 1/3 ensures broad compatibility with industrial sensors and input devices.
Performance characteristics of the KL1819 emphasize rapid response and low interference for mission-critical applications. Each channel exhibits a typical input filter delay of 0.2 ms, minimizing signal noise and ensuring swift logic transitions. The module’s "0" signal voltage range of -3…+5 V and "1" signal voltage range of 11…30 V conform strictly to EN 61131-2, type 3 specifications, guaranteeing unambiguous digital recognition. It draws only typ. 3 mA per input channel, while the current consumption on the K-bus is typ. 20 mA and power contact consumption stands at typ. 4 mA + load. Internally, the KL1819 maps all channels directly into the process image as a bit width of 16 inputs, facilitating straightforward programming and high-speed data exchange.
Reliability and seamless integration underpin the KL1819’s appeal in advanced automation systems. Rated for an operating temperature range of -25…+60 °C and a storage temperature window of -40…+85 °C, the module tolerates harsh environmental conditions and thermal cycling. Its compact dimensions support dense module populations on standard mounting rails, optimizing cabinet footprint. Backed by a one-year warranty, the KL1819 ensures dependable performance in sectors such as conveyor control, packaging machinery, and remote I/O distribution. When paired with Beckhoff’s CX or TwinCAT controllers, this module delivers a reliable, high-speed interface for digital inputs across diverse industrial automation applications.
