Information About KL3458
The KL3458 is part of Beckhoff’s KL series of analog input terminals, designed for efficient acquisition of multiple current signals within distributed automation systems. It processes 4…20 mA signals across eight channels, digitizing them with 12-bit resolution and transmitting them securely via the K-bus to higher-level controllers. Its compact 12 mm housing allows high packing density, making it an excellent choice for applications requiring many input channels in limited cabinet space. With overload detection, surge resistance, and LED status indicators, the KL3458 ensures reliable and safe operation in industrial environments.
Key Features:
-
Eight Analog Input Channels: Provides 8 single-ended channels for acquiring current signals in the 4…20 mA range.
-
High-Resolution Measurement: Converts signals with 12-bit resolution, ensuring accurate data for automation tasks.
-
Compact High-Density Design: Combines eight inputs in a slim 12 mm housing, optimizing control cabinet space.
-
Robust Electrical Isolation: Offers 500 V separation between K-bus and signal voltage for secure operation.
-
Overload and Wire-Break Detection: Includes diagnostics via error LEDs to identify signal issues quickly.
-
Fast Signal Processing: Achieves ~4 ms conversion time for responsive current measurement.
-
Industrial Reliability: Withstands up to 30 V surge protection and maintains < ±0.3% measurement error.
-
Seamless System Integration: Connects directly via K-bus with no additional addressing or configuration required.
The KL3458 delivers the reliability and precision required for space-efficient current signal acquisition in automation systems.
