Siemens 6ES5441-4UA13 Digital Output Module for SIMATIC S5

The Siemens 6ES5441-4UA13 drives actuators and indicators from SIMATIC S5 PLCs. You can install this module directly into any standard S5 rack slot. It provides sixteen transistor output channels for 24 V DC loads. This unit suits solenoid valves, contactors, and signaling lamps.

Technical Specifications and Hardware Layout

This digital output module measures 233 mm in height. Its width reaches 54 mm, and the depth equals 182 mm. The Siemens 6ES5441-4UA13 weighs approximately 0.72 kilograms. A single internal PCB holds all output driving and isolation circuits. The module provides sixteen sinking transistor outputs for DC loads. It stores no energy in capacitors or internal batteries. One 48-pin front connector handles all field wiring connections. Sixteen red LEDs display the real-time status of each channel.

Output Specifications and Electrical Ratings

The Siemens 6ES5441-4UA13 switches outputs at 24 V DC nominal. Each channel handles a continuous current of 0.5 A maximum. The total current per common group reaches 4 A. Short-circuit protection shuts down an individual channel during overload. Consequently, this module survives wiring faults without permanent damage. Output switching frequency reaches 100 Hz for rapid cycling tasks. Each channel includes an internal freewheeling diode for inductive loads. The module’s optical isolation separates the field side from the backplane logic.

Installation and Practical Application Tips

You must snap this module firmly into a standard S5 rack slot. Transitioning to wiring, use 0.5 mm² to 1.5 mm² stranded copper wire. The screw-type terminals require a 3 mm flathead screwdriver for tightening. For inductive loads, the internal diodes provide adequate suppression. The operating temperature range extends from 0°C to 60°C reliably. This module consumes only 80 mA from the backplane bus.
