KL1408 Beckhoff 8-channel Digital Input Terminal 24VDC 3.0 Ms 5 MA 500 Vrms
1.Overview of the KL1408 Beckhoff
The KL1408 is a high-density, 8-channel digital input terminal module from Beckhoff, Germany, designed specifically for industrial automation control systems. Using single-wire connection technology, it transmits binary 24 V DC control signals from the field to the host controller in an electrically isolated manner. It is a key component of the Beckhoff Bus Terminal I/O system.
Key Features
8-Channel Digital Input: Each terminal integrates eight independent channels, significantly saving control cabinet space and improving system integration.
Galvanic Isolation: 500 Vrms (K-bus/field potential) isolation effectively suppresses field interference and ensures stable system operation.
LED Status Indicator: Each channel features a separate LED that displays the input signal status in real time, facilitating on-site commissioning and maintenance.
Input Filtering: Built-in 3 ms input filtering eliminates mechanical switch chatter and improves signal reliability.
Single-Wire Connection: Utilizing single-wire technology, wiring is simplified, reducing wiring effort and installation costs. Low-power operation: The K-bus consumes only 5 mA, reducing overall system energy consumption and making it suitable for large-scale I/O expansion.
