GKR04-2S LENZE

GKR04-2S analog module

Product  Description：

Lenze Analog Modules, particularly prominent within the Lenze I/O System 1000 and the decentralized g500/8400 drive series, are highly precise signal acquisition and generation components. These modules serve as the analytical sensor and actuator interfaces for advanced motion control and machine automation architectures. They convert real-world continuous variables—such as pressure, speed, temperature, and torque—into digital values for processing by a central controller, or conversely, transform digital controller commands into smooth analog outputs to modulate drive systems.

Product Parameters

The technical baseline of Lenze Analog Modules focuses on precision conversion rates and diverse signal compatibility:

• Signal Configurations: Multi-channel options supporting standard voltage input ranges of 0 to 10V DC and -10 to 10V DC, as well as current loop ranges of 0 to 20mA and 4 to 20mA DC.

• Digital Resolution: High-fidelity processing utilizing 12-bit or 16-bit Analog-to-Digital (A/D) and Digital-to-Analog (D/A) resolution parameters, providing precise quantization of process signals.

• Internal Cycle and Conversion Time: Optimized for high-speed cyclic production, with standard conversion times averaging 2 to 4 milliseconds across all channels, or faster for specialized motion capture.

• Backplane Bus Power Consumption: Extremely low overhead, typically drawing approximately 70mA from the internal 5V or 24V DC backplane communication rail.

• Destruction and Overvoltage Limits: Integrated circuit safety tolerances with a destruction threshold commonly rated up to 30V DC for voltage inputs and 40mA for current loops.

• Galvanic Isolation: Robust dielectric isolation, typically verified at 500V DC between individual channels, the internal backplane bus, and the primary I/O power supply.

Product Advantages

Lenze Analog Modules provide distinctive performance features optimized for machine manufacturing and synchronized multi-axis operations:

• Ultra-Slim and Modular Design: With a slice width often measuring a mere 12.5 mm, these modules optimize cabinet density and minimize physical mounting space.

• Precise Synchronized Touch Probe Inputs: Designed to handle microsecond-level time-stamped signals, ensuring that high-speed position or registration data is transferred to the motion bus without jitter.

• Integrated Parameterizable Filters: Advanced internal data smoothing functions allow engineers to activate software filtering via commissioning tools, effectively suppressing high-frequency interference.

• Intelligent Status and Out-of-Range Indicators: Equipped with multi-colored channel-specific LEDs that flag wire-break scenarios or out-of-range sensor currents instantly, streamlining local hardware diagnostics.

• Tool-Free Assembly and Wiring: Utilizes standard spring-clamp terminal blocks and a clip-on DIN rail design, which eliminates manual screwing and reduces assembly errors during field deployment.

Product Applications

These analog interface modules are crucial for coordinating high-precision machinery and material handling applications:

• Intralogistics and Conveyor Drives: Interfacing with ultrasonic distance sensors to provide smooth acceleration and braking profiles on synchronized sorting lanes.

• Specialized Tension Control: Managing signal tracking from load cells and dancer arms in textile, paper-converting, and winding machinery to maintain uniform material tension.

• Extrusion and Thermal Regulation: Processing real-time feedback from high-temperature RTD or thermocouple transmitters used in plastic molding and food processing equipment.

• Variable Speed Pump and Fan Control: Delivering precise speed references to Lenze 8400 or i500 inverters based on continuous fluid flow or air pressure feedback.

• Test Benches and Dynamometers: Capturing high-resolution torque and mechanical strain data via specialized strain gauge analog input slices.

Important Precautions

To preserve signal fidelity and safeguard internal electronics against premature failure, the following directives must be executed:

• Strict Voltage Limitation: The input electronics are not natively protected against excessive overvoltages. Ensure that the sensor output voltage never exceeds the designated module limit to prevent catastrophic burning of the input circuit.

• Single-Point Shielding Protocols: Always implement high-quality shielded twisted-pair cables for all analog runs. The cable shield must be terminated cleanly at a single designated ground point to avoid circulating ground loops.

• Wiring Segregation Boundaries: Run all low-voltage analog paths through isolated wire trays situated at least 100mm away from three-phase AC motor leads and high-power inverter output cables.

• Configuration of Unused Channels: Unused analog channels can pick up ambient electromagnetic noise and generate false errors. Deactivate unused loops within the programming software or short-circuit the corresponding terminal points.

• Terminal Strip Length Management: When stripping field wires for insertion into the spring-clamp terminals, strictly adhere to the 10mm specification. Exposed bare conductors can result in inter-channel short circuits or contamination-induced faults.
