Each of its eight channels includes LED indicators that clearly show input states, simplifying diagnostics and commissioning. The terminal implements a 3 ms input filter, which prevents mechanical switch bounce and improves signal accuracy during operation. With a 1-wire connection system and compact IP20 housing, the KL1408 integrates easily into control cabinets and supports efficient signal handling in industrial automation environments. Key Features Eight-channel digital input module: captures multiple 24 V DC signals for flexible process-level monitoring. Fast signal processing: 3 ms input filter reduces switch bounce and improves stability of mechanical input devices. Compact Bus Terminal form factor: fits densely into automation racks while maintaining full channel functionality. LED status indication: provides clear channel-by-channel signal visualization for easy troubleshooting and commissioning. 1-wire connection system: simplifies wiring and supports rapid installation in distributed I/O assemblies. Wide operating temperature range: functions reliably from −25°C to +60°C for diverse industrial environments. IP20 protection class: suitable for enclosed cabinet installations with standard control hardware. Type 1/3 input specification: ensures compatibility with a broad range of digital field devices and sensors. The KL1408 delivers the reliability and precision required for accurate 24 V DC signal acquisition in modern industrial automation systems.
