Beckhoff KL3172 2-Channel Analog Input Terminal

Overview

KL3172 Original New in Stock

Parameters

Note: Specifications are indicative. The KL3172 is a K-Bus analog input terminal with diagnostics. Exact resolution, accuracy, input impedance, supported diagnostic functions, and update rates must be verified against the current Beckhoff datasheet for your revision. The KL series differs from the EtherCAT EL series in the bus system used.

Core Advantages

1. Monitored 0–10 V Input
Combines standard 0–10 V voltage measurement with integrated diagnostics, enabling both signal acquisition and fault visibility in one terminal.

2. Integrated Input Diagnostics
Provides diagnostic feedback on input status and fault conditions (e.g., overrange/underrange, wire break where supported), enabling faster fault detection and reduced downtime.

3. Two Inputs in a 12 mm Housing
Two independent analog voltage inputs with diagnostics in a compact Bus Terminal housing, suitable for critical dual-sensor acquisition in K-Bus systems.

4. Standard 0–10 V Interface
Measures the widely used 0–10 V signal, compatible with a broad range of sensors, transmitters, and analog signal sources.

5. Per-Channel Configuration
Measurement scaling and filter settings are configurable per channel through the Bus Coupler/Controller. Confirm the exact configuration options in the datasheet.

6. K-Bus System Integration
Integrates into the Beckhoff Bus Terminal system via the K-Bus, working with Bus Couplers and Bus Terminal Controllers for fieldbus connectivity.

7. Channel-Wise Status and Diagnostic LEDs
LEDs per channel indicate input state and diagnostic conditions, supporting fast commissioning and troubleshooting.

Applications

• Monitored sensor acquisition — 0–10 V pressure, flow, level, and position transmitters requiring fault feedback.

• Machine building — analog signal acquisition with diagnostics in motion, clamping, and process control.

• Process technology — measurement of standard analog process signals with fault detection.

• Legacy K-Bus systems — expansion and maintenance with diagnostic capability.

• OEM equipment — embedded diagnostic analog input in industrial machines.

• Test benches — analog signal acquisition with monitoring in validation and R&D rigs.

• Building automation — 0–10 V sensor acquisition with diagnostics for HVAC and energy systems.

FAQ

Q1: What is the KL3172 used for?
It is a 2-channel analog input terminal with integrated diagnostics for the Beckhoff K-Bus Bus Terminal system, used to measure 0–10 V voltage signals from sensors and transmitters with fault feedback.

Q2: What is the difference between KL3062 and KL3172?
Both are 2-channel 0–10 V analog input terminals for the K-Bus system; the KL3172 adds integrated diagnostics for input status monitoring. Confirm the exact differences in the current datasheet.

Q3: What is the difference between KL3162 and KL3172?
The KL3162 measures bipolar ±10 V with 16-bit resolution and diagnostics; the KL3172 measures unipolar 0–10 V with diagnostics. Choose based on signal polarity and resolution requirements.

Q4: What diagnostic functions are supported?
Diagnostics may include overrange, underrange, and wire break (where supported) detection depending on configuration. Confirm the exact supported diagnostic functions in the current datasheet.

Q5: What resolution does it provide?
Typically 12-bit resolution, but the exact resolution must be confirmed in the current datasheet.

Q6: How is the terminal configured?
Configuration is performed through the Bus Coupler or Bus Terminal Controller (e.g., via KS2000 or TwinCAT). Confirm the exact workflow in the datasheet.

Q7: Does it require an external 24 V supply?
The terminal logic is powered from the K-Bus; the analog input stage may require a field supply depending on the variant. Confirm the exact supply requirements in the datasheet.

Q8: Is the KL3172 suitable for safety functions?
No. It is a standard automation terminal and is not a certified safety component. Use appropriately certified hardware for safety-related signal acquisition.
