KEBA DI-325/B Digital Input Module Detailed Product Description I. Product Overview
KEBA DI-325/B Digital Input Module Detailed Product Description I. Product Overview
The KEBA DI-325/B is a 32-channel digital input module produced by the Austrian KEBA factory. It is compatible with all series of industrial control systems from KEBA and is specifically designed for the multi-channel switch signal acquisition of large-scale automation equipment. The module adopts a standard rack structure and integrates 32 isolated input points. It has industrial-level anti-interference, wide temperature operation, and stable bus communication capabilities. It is widely used in injection molding machines, large machine tools, automated production lines, die-casting machinery and other main industrial equipment, and is a core component for large-capacity signal acquisition in the automation control system.
II. Core Functions
32 Independent Digital Inputs
It integrates 32 integrated input channels, which can simultaneously connect various on-site switch signals. The number of points is sufficient to meet the centralized acquisition requirements of the entire machine for multiple points such as limit switches, sensors, buttons, alarms, and travel detection, significantly reducing the number of module installations.
** Standard 24V DC Industrial Input Standard
It is compatible with mainstream industrial 24V DC signals and can be compatible with all common on-site input elements such as NPN-type sensors, photoelectric switches, proximity switches, mechanical limit switches, emergency stop switches, and relay passive contacts. It has extremely strong versatility.
Photoelectric Isolation Anti-interference Design
The module uses a photoelectric isolation architecture, completely isolating the strong interference side lines from the internal circuits of the control system, effectively isolating electromagnetic waves generated by motors, frequency converters, and solenoid valves, eliminating signal mis-triggering and signal drift, and ensuring stable equipment operation.
Intuitive Channel Status Display
Each input channel is equipped with an independent status indicator light. The indicator light is on when the signal is connected, and off when the signal is disconnected. This makes on-site debugging, line maintenance, and fault troubleshooting clear and straightforward, significantly reducing the difficulty of operation and maintenance.
Built-in Multiple Electrical Protection
It comes with input overvoltage protection, reverse voltage protection, channel current limiting protection, and static protection functions, which can withstand instantaneous voltage fluctuations in the on-site lines and incorrect wiring operations, and is less likely to be damaged by external line faults.
High-speed Stable Bus Communication
It seamlessly connects with the KEBA dedicated system bus, with rapid signal upload response and strong real-time data transmission, without any delay or packet loss, and can precisely match the high-speed operation control logic of the equipment.

VI. Installation, Use and Maintenance Instructions
When the equipment is powered off, smoothly insert the DI-325/B into the corresponding slot on the main control rack of the KEBA system. Ensure that the back bus interface is closely adhered and locked. According to the equipment's electrical drawing, uniformly and neatly connect the 24V input signal lines, distinguish the positive and negative poles of the lines, and avoid reverse connection or incorrect connection.
During daily use, simply observe the indicator lights on the panel to determine the signal connection status. Regularly clean the dust accumulated on the module surface to ensure smooth ventilation and heat dissipation. When there is a signal anomaly, prioritize troubleshooting the external lines and sensing elements. After confirming that the line troubleshooting is correct, then test the module status. Under normal working conditions, almost no daily maintenance is required.
