Siemens 6ES5456-6AA11 Digital Output Module

This digital output module drives actuators and indicators from SIMATIC S5 systems. It converts internal logic signals into field-ready 24V DC switching power. Therefore, this component controls solenoids, contactors, and signal lamps reliably.

Physical Dimensions and Weight Specifications

The Siemens 6ES5456-6AA11 occupies one standard slot in the S5 rack. Its housing measures 233 mm in depth for backplane connectivity. The module weighs approximately 0.42 kg for easy handling during installation. Consequently, technicians can mount this unit without additional rack reinforcement.

Interface Types and Connection Layout

The Siemens 6ES5456-6AA11 provides a 48-pin front connector for field wiring. A separate 20-pin backplane connector supplies power and data signals. The front panel carries one LED indicator per output channel. Hence, operators can see switching states from a distance.

Component Count and Channel Configuration

This module contains one main PCB with eight independent output channels. Each channel uses a power MOSFET rated for 0.5A continuous current. You will also find optocouplers isolating each output from the backplane bus. An onboard snubber diode protects each transistor from inductive load spikes.

Energy Storage and Switching Performance

The Siemens 6ES5456-6AA11 includes a small capacitor per output channel. These capacitors absorb transient energy from inductive loads. The module switches outputs on or off within 150 microseconds. This fast response suits high-speed sorting and positioning applications.

Protection Features and Operating Limits

Each output channel includes short-circuit protection with automatic restart. The module also features overtemperature shutdown for the entire driver array. Users can operate this unit in temperatures from 0°C to 55°C. A common ground connection simplifies wiring for all eight channels.
