Module Capabilities

The Schneider ASB804016 output module delivers 16 discrete channels for driving solenoids and indicator lamps. This compact unit belongs to the Modicon 800 series I/O family. It provides high-side switching with built-in short-circuit protection. Machine builders rely on this module for reliable actuator control.

Channel Configuration and Output Ratings

Each of the 16 outputs delivers 0.5 amperes at 24 V DC continuously. The module supports inductive loads up to 1 henry without external suppression. It also drives resistive and capacitive loads with equal reliability. All channels share a common power return connection. This architecture simplifies field wiring for grouped loads significantly.

Protection Features and Fault Tolerance

The Schneider ASB804016 incorporates thermal shutdown for overtemperature conditions. It includes overload protection that limits current at 1.2 amperes per channel. A diagnostic feedback signal reports open-load or short-circuit faults. The module automatically restores output after clearing the fault condition. This self-protection reduces downtime and replacement costs.

LED Status Indication

Sixteen green LEDs display the real-time on/off state of each output. A single red LED signals any module-level fault or communication error. These indicators help operators verify field device activation quickly. The front panel includes clear labeling for each channel number. This visibility simplifies troubleshooting during system commissioning.

Communication and Backplane Interface

The module interfaces with the rack backplane using an 8-bit parallel protocol. It exchanges I/O status data with the CPU every scan cycle. The unit supports both local and remote rack configurations seamlessly. Configuration software automatically assigns the module’s I/O addresses. This plug-and-play behavior accelerates system setup significantly.

Physical Dimensions and Mounting

This output module measures 130 millimeters in width and 55 millimeters in height. Its depth totals 75 millimeters including the front connector. The unit weighs 0.38 kilograms for easy installation. It slides into any standard slot of the ASH827103 rack. A locking lever secures the module firmly in position.

Electrical Characteristics and Power Consumption

The Schneider ASB804016 draws 80 milliamperes from the 5 V DC backplane. It also requires 50 milliamperes from the external 24 V DC supply. Total power dissipation reaches 2.5 watts under full load. The module uses MOSFET output stages for efficient switching. This semiconductor design minimizes heat generation inside the cabinet.

Field Wiring and Connector Details

A removable 20-pin screw terminal block accepts field wiring connections. The terminals accommodate wire sizes from 0.2 to 1.5 square millimeters. Each channel includes an individual fuse holder for optional protection. The connector block features polarized keys to prevent incorrect insertion. This design simplifies field maintenance and module replacement.

Environmental Ratings

The unit operates between 0°C and 55°C ambient temperature. It tolerates humidity from 5% to 95% without condensation. The module meets EN 61131-2 standards for industrial control equipment. Its IP20-rated housing protects against accidental contact. The design includes conformal coating for moisture resistance.
