KEBA AF455/A Analog Card K2-400
The AF455/A Analog Card is a component designed for KEBA Kemro K2-400 injection molding machine controllers, specifically tailored for handling analog signals in industrial automation applications. Below is a detailed breakdown of its features, functions, and relevance to the KEBA system:
Key Features of the AF455/A Analog Card
- Analog Signal Processing
- Supports 4 analog input channels (e.g., for pressure, temperature, or position sensors).
- May include 2 analog output channels (for controlling valves, heaters, or actuators).
- Handles 0–10V DC or 4–20mA signals (common in industrial sensors).
- Compatibility
- Designed for KEBA Kemro K2-400 controllers, a modular PLC system used in injection molding machines.
- Integrates with KEBA’s KemroView HMI software for configuration and monitoring.
- Precision & Reliability
- High-resolution ADC/DAC converters for accurate signal processing.
- Industrial-grade design (wide temperature range, shock/vibration resistance).
- Diagnostics & Safety
- Built-in self-test functions for fault detection.
- May support overvoltage/undervoltage protection for analog inputs.
Applications in Injection Molding
The AF455/A is used to interface with sensors and actuators critical to the injection molding process, such as:
- Mold temperature control (via thermocouples or RTDs).
- Hydraulic pressure monitoring (e.g., clamp force, injection pressure).
- Position feedback (e.g., screw position, ejector movement).
- Output control (e.g., regulating heater bands, proportional valves).

Integration with KEBA Kemro K2-400
- The card plugs into the K2-400’s backplane, allowing seamless communication with the CPU.
- Configuration is done via KemroView software, where users can assign input/output ranges, scaling, and alarms.
- Supports real-time data logging for process optimization.
Troubleshooting & Maintenance
- Common Issues:
- Noisy signals (check shielding/grounding).
- Offset errors (recalibrate in KemroView).
- Card not detected (verify backplane connection).
- Maintenance:
- Regular cleaning of connectors.
- Periodic calibration (if required by KEBA guidelines).
Alternatives & Upgrades
- KEBA may offer newer versions (e.g., AF455/B) with enhanced features like higher resolution or additional channels.
- Third-party analog cards may be compatible but require KEBA certification for safety-critical applications.
Where to Buy
- Official KEBA Distributors: Ensure compatibility and warranty support.
- Industrial Automation Suppliers: Such as RS Components, Farnell, or Digi-Key (if stocked).
- Used/Refurbished Markets: For cost savings, but verify authenticity.
