System compatibility

This set belongs to MODICON Compact A120 series rack system. Compatible with Compact series CPU and power supply modules. The rack carries DAO216 output and DEO216 input modules to build discrete on-off control system. Suitable for packaging machinery, conveyor systems, small process skid legacy automation system renovation and replacement as industrial spare part.

Function

A120 Aluminium 200 is the aluminium rack with built-in backplane bus, it provides mechanical mounting and bus signal transmission for I/O modules. DEO216 (AS-BDEO-216): 16-channel 24VDC digital input module, collects on/off signals from field limit switches, push buttons and proximity sensors, transmits status to PLC CPU. DAO216 (AS-BDAO-216): 16-channel 24VDC digital output module, receives logic commands from PLC, switches field loads such as solenoid valves, indicator lights and auxiliary relays. Each module has LED channel status indication and built-in hardware self-diagnosis. Widely used for machine discrete control in legacy MODICON Compact automation system.

Installation

Cut off rack power before installation. Mount A120 Aluminium 200 rack on DIN rail. Insert DEO216 and DAO216 modules into rack slots and lock. Check gold finger contact condition. Connect field sensor and actuator wiring to module terminal blocks. Configure I/O address mapping, test input reading and output action, complete function test before formal operation.

Interface

Backplane bus connector on rack, field terminal blocks for DEO216 DI and DAO216 DO, channel status LED indicators for each I/O module.

Feature

MODICON A120 Aluminium 200 Compact aluminium rack, sturdy aluminium frame, integrated backplane bus. DEO216 16-point 24VDC input, DAO216 16-point 24VDC output, per-channel LED indication, industrial anti-interference design. This discontinued legacy industrial spare part set used for old MODICON Compact PLC discrete I/O control maintenance and replacement.

Diagnostic

Rack module not detected: check rack backplane power supply and module seating for A120 assembly. DEO216 no input reading: inspect field sensor 24VDC supply, wiring polarity and wire breakage. DAO216 no output action: verify PLC program logic, load wiring and terminal contact. Intermittent I/O fault: check loose terminals and component aging.

Product Brief

A120 ALUMINIUM 200 + DAO 216 + DEO 216 is AEG MODICON Compact series aluminium rack assembly with 16-point digital input and 16-point digital output modules. It forms a complete discrete I/O station for Modicon Compact PLC, classic spare part for legacy industrial machine automation overhaul.
