Grundig NEA02 AES 0 Digital I O Module for Deckel Dialog 112 PLC Systems

Product Overview

The Grundig NEA02 AES 0 is a digital input/output module specifically designed for use with Deckel Dialog 112 programmable logic controllers, commonly found in CNC milling machines and other industrial equipment. This module provides signal conditioning and isolation between the PLC and field devices such as limit switches, pushbuttons, relays, and solenoid valves. The NEA02 AES 0 is part of Grundig's automation component series and is essential for maintaining and repairing Dialog 112 controlled machinery. It is built for reliability in industrial environments.

Key Features of NEA02 AES 0

The module typically offers a combination of digital inputs (8-16 channels) and digital outputs (8-16 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. Outputs are protected against short circuits and overloads. LED indicators provide per-channel status for easy troubleshooting. The module connects to the Dialog 112 controller via a ribbon cable or backplane connector, and to field wiring via removable screw terminal blocks. It is powered by 24 V DC from the system.

The NEA02 AES 0 is designed for DIN rail mounting and has a compact footprint. It operates in temperatures from 0 to 55°C. The module is a direct replacement for failed I/O boards in Deckel Dialog 112 systems. It complies with relevant CE and RoHS standards.

Functional Description

The NEA02 AES 0 interfaces between the Dialog 112 CPU and field devices. Input channels read 24 V DC signals from sensors and switches, opto-isolate them, and pass the logic levels to the CPU. Output channels receive commands from the CPU and drive external loads. The per-channel LEDs indicate the state of each I/O point for quick diagnostics. The module can be replaced without re-wiring if removable terminal blocks are used. The module is essential for keeping older Deckel Dialog 112 controlled machines operational.

Applications

This I/O module is used in Deckel Dialog 112 CNC milling machines, machining centers, and other Grundig-controlled industrial equipment. It serves as a spare or replacement part for maintenance and repair.
