Beckhoff KL3454 is a standard bus terminal module under the KL series Bus Terminal system, serving as a 4-channel analog input terminal matched with Beckhoff PLC main controllers. It converts external analog voltage or current field signals into digital signals and transmits data to the upper PLC control system via the backplane bus. This module collects analog data from on-site sensors including pressure transmitters, temperature transmitters, flow sensors and level sensors, realizing real-time analog signal acquisition for industrial automatic closed-loop control, data monitoring and parameter feedback.
4 Independent Analog Input Channels Four fully isolated signal acquisition channels, supporting simultaneous sampling of multiple field analog signals to expand PLC analog input points efficiently.
12-bit High Resolution Conversion 12-bit A/D conversion ensures stable signal acquisition with low quantization error, meeting general industrial measurement and control precision requirements.
Wide Standard Signal Compatibility Supports universal industrial analog signals: 0–10 V voltage signal and 4–20 mA current signal, compatible with most mainstream industrial sensors on the market.
Channel-wise Electrical Isolation Design Each input channel features isolation protection, effectively suppresses electromagnetic interference from field equipment and avoids cross-talk between different signal loops.
Compact Modular DIN Rail Installation Standard Bus Terminal slim housing, snap-on DIN rail mounting, freely combined with other KL series digital/analog modules to build customized I/O stations flexibly.
Intuitive LED Status Indicator Built-in channel status LED lights for power indication and channel fault diagnosis, allowing quick troubleshooting without extra debugging tools.
Stable Backplane Bus Communication Data transmission via Beckhoff standard K-bus backplane, high anti-interference ability and reliable long-term operation in cabinet environments.
