The Beckhoff KL3202 is a high-precision, 2-channel analog input terminal from the Beckhoff Bus Terminal (BK) system. It is designed for the reliable acquisition of standard voltage and current signals in industrial automation and control applications. As part of the versatile Beckhoff I/O system, the KL3202 connects directly to sensors and transmitters, converting their analog signals into digital process data for the PLC.
This module is an essential component for engineers and system integrators who require accurate and robust measurement of process variables like pressure, temperature, flow, or level within a centralized or decentralized EtherCAT automation architecture.
Key Features & Benefits
-
Dual-Channel Versatility: Two isolated input channels in a single, compact module, saving space and cost in control cabinet design.
-
Wide Signal Range Support: Configurable per channel for voltages of ±10 V and currents of 0/4…20 mA, making it compatible with a vast array of industrial sensors.
-
High Resolution: Features a 16-bit analog-to-digital converter, ensuring precise measurement and fine resolution of the input signal for accurate process monitoring and control.
-
Internal Supply for Sensors: Includes an integrated 24 V supply for 2-wire measuring transducers (current loop power), simplifying wiring and eliminating the need for an external power source for the sensors.
-
Electrical Isolation: The channels are electrically isolated from the bus terminal (K-bus). This protects the sensitive control system from potential damage caused by ground loops or electrical noise in the field.
-
Seamless Integration: Fully integrates with the Beckhoff TwinCAT automation software. Configuration and parameterization are handled effortlessly within the engineering environment.
