Siemens 6ES5444-1AA22 Output Card

This output card drives actuators from SIMATIC S5 PLC systems. It provides 32 digital channels for controlling solenoids, contactors, and indicators. Therefore, this component suits factory automation and machine control applications.

Physical Dimensions and Weight Specifications

The Siemens 6ES5444-1AA22 occupies one standard slot in the S5 rack. Its housing measures 233 mm in depth for backplane connectivity. The module weighs approximately 0.46 kg for straightforward handling. Consequently, technicians can install this unit without additional rack reinforcement.

Interface Types and Connection Layout

The Siemens 6ES5444-1AA22 provides a 48-pin front connector for field wiring. A 20-pin backplane connector supplies power and data from the CPU. The front panel carries 32 green LED indicators for output status. Hence, operators can monitor all channels at a quick glance.

Component Count and Channel Configuration

This output card contains one main board with 32 transistor output channels. Each channel provides 0.3A continuous current at 24V DC. You will also find optocoupler isolation between the backplane and field side. An onboard serial-to-parallel converter reduces backplane pin count.

Energy Storage and Power Consumption

The Siemens 6ES5444-1AA22 draws 95 mA from the 5V backplane supply. It requires an external 24V supply for output load power. A small capacitor bank absorbs voltage spikes from inductive loads. This storage protects the transistors during solenoid switching events.

Output Performance and Diagnostic Features

The module updates all 32 outputs within a 1 ms cycle time. Each channel includes short-circuit detection with automatic shutdown. Users can read diagnostic status via the S5 programming software. This feature reduces downtime during field wiring faults.
