MeloAuto-Trusted PLC & DCS Parts Supplier
This Siemens digital output module provides high-density switching with diagnostic capabilities. The Siemens 6ES5441-8MA11 drives up to 32 output channels for extensive control tasks. Its advanced design includes comprehensive fault detection for reliable operation. This module suits complex machine control and process automation applications. The Siemens 6ES5441-8MA11 delivers robust performance with integrated monitoring features.
Physical Dimensions and Mounting Specifications
The module measures 232 mm in height and 25 mm in width. Its overall depth reaches 160 mm including the front connector. This unit weighs approximately 0.58 kilograms for stable rack installation. The housing supports standard 35 mm DIN rail mounting in S5 racks. The Siemens 6ES5441-8MA11 features a 48-pin front connector for all output wiring. This connector accepts conductor cross-sections from 0.5 mm² to 2.5 mm².
Output Specifications and Electrical Characteristics
Each output channel provides a switching capacity of 0.5 A at 24 V DC. The total current per module reaches 8 A across all active channels. Output voltage ranges from 20.4 V to 28.8 V DC for reliable operation. The module draws a typical current of 180 mA from the backplane supply. The Siemens 6ES5441-8MA11 includes internal flyback diodes for inductive load protection. Each channel features short-circuit protection with automatic current limiting. An LED indicator shows the status of each individual output channel.
Diagnostic and Monitoring Features
This module provides read-back capability for output status verification. It detects open-circuit and short-circuit conditions on each channel. A common fault output signals any detected errors for system monitoring. The module includes thermal protection against overload conditions. The Siemens 6ES5441-8MA11 stores fault events in an internal diagnostic buffer. This buffer holds the last 20 fault records for troubleshooting. Output turn-on delay measures approximately 0.5 milliseconds for fast response. Turn-off delay reaches 1 millisecond for consistent switching performance.

Application and Wiring Guidelines
Mount this module in any available slot of the S5 rack system. Connect the output devices to the designated terminals on the front connector. Use twisted-pair cables for long-distance wiring to reduce interference. The Siemens 6ES5441-8MA11 operates effectively between 0°C and 60°C. Ensure adequate clearance around the module for proper heat dissipation. Wire the common return line to the 24 V DC ground terminal. Monitor the diagnostic LEDs and read-back data for fault detection.
