The Grundig NEA02 AES 0 is a digital input/output module designed for use with Lid Dialog 112 programmable controllers and other Grundig automation systems. This module provides signal conditioning and isolation between field devices and the PLC, enabling reliable data exchange in industrial applications such as material handling, packaging, and assembly machinery. The NEA02 AES 0 is built for operation in demanding environments, with robust electrical characteristics and protection against overvoltage and transient surges. It is part of Grundig's automation component family, known for compatibility with legacy systems.
The module typically offers a mix of digital inputs (e.g., 8 or 16 channels) and digital outputs (e.g., 8 or 16 channels), with input ratings of 24 V DC and output ratings of 24 V DC / 0.5 A per channel. Inputs are opto-isolated from the controller logic, preventing ground loops and electrical noise from affecting the PLC. Outputs are protected against short circuits and overloads. The module includes LED indicators for power and per-channel I/O status, facilitating on-site diagnostics. It connects to the controller via a ribbon cable or backplane connector and to field wiring via removable screw terminal blocks.
The NEA02 AES 0 operates from a 24 V DC power supply and consumes approximately 100 mA. It is designed for DIN rail mounting and has a compact footprint, allowing efficient use of control cabinet space. The operating temperature range is 0 to 55°C, with storage from -20 to 70°C. The module is certified for CE compliance. It is a direct replacement part for Lid Dialog 112 systems and can also be used in other Grundig automation racks.

The NEA02 AES 0 module interfaces between field sensors/actuators and the Lid Dialog 112 PLC. Input channels convert 24 V DC signals from switches, proximity sensors, or limit switches into logic levels readable by the PLC. Output channels receive logic signals from the PLC and drive external devices such as solenoid valves, contactors, or indicator lamps. The opto-isolation prevents electrical noise from the field wiring from reaching the controller, ensuring reliable operation. The diagnostic LEDs show the status of each channel, allowing operators to quickly identify faults.
The Grundig NEA02 AES 0 is used in legacy Grundig and Lid Dialog 112 automation systems, typically in small to medium industrial machinery, including packaging machines, conveyor control, and assembly lines. It serves as a replacement module for failed I/O boards.
