Description

The Siemens 6ES5441-8MA11 is a digital output module from the SIMATIC S5 441 series, engineered for use with the S5-90U, S5-95U, S5-100U, ET 100U, and ET 200U compact PLC systems . This non-isolated (non-floating) module provides 8 transistor outputs at 24V DC, each capable of delivering 0.5A, serving as the primary interface for the PLC to drive field actuators such as small solenoid valves, signaling lamps, and interposing relays .

The 6ES5441-8MA11 represents a cost-effective and reliable output solution for applications where galvanic isolation is not a critical requirement . As part of the SIMATIC S5 platform, this module has become an essential spare part for the extensive installed base of S5 systems still operating in manufacturing and process facilities worldwide. The module utilizes electronic transistor switching to ensure high-frequency response and wear-free operation compared to mechanical relay outputs .

 

Application Scenarios

In a mid-sized automotive parts manufacturing plant operating an S5-95U-controlled assembly conveyor system, the Siemens 6ES5441-8MA11 plays a critical role in actuating pneumatic cylinders and controlling indicator lamps along the production line. When the plant’s original output modules began showing signs of wear and intermittent failures due to age, the maintenance team replaced them with the 6ES5441-8MA11. The module’s 0.5A per channel capacity proved sufficient to drive the plant’s small solenoid valves and pilot relays, restoring reliable machine sequencing and eliminating production stoppages caused by output failures .

The Siemens 6ES5441-8MA11 finds its primary application in small to medium-scale automation systems using the S5-90U, S5-95U, and S5-100U platforms . Typical deployments include conveyor control systems actuating diverters and stops, packaging machinery controlling sealing bars and cutters, machine tools managing coolant valves and work lights, assembly lines operating pneumatic actuators and pick-and-place devices, and small process skids controlling dosing valves and alarms . The module’s compact design and non-isolated architecture make it an ideal choice for applications with standard output requirements where cost efficiency is prioritized over isolation .
