Description

The Siemens 6ES5441-7LA12 is a high-density digital output module from the SIMATIC S5 441 series, engineered for the S5-115U and S5-115H PLC systems. This non-isolated module provides 32 discrete output channels operating at 24V DC, each capable of driving up to 0.5A.

Designed for space-constrained control cabinets, the Siemens 6ES5441-7LA12 delivers 32 outputs in a single module slot, offering exceptional I/O density for large-scale automation systems. Its non-isolated design provides a cost-effective solution for standard actuator control applications where all outputs share a common reference potential.

Application Scenarios

A large automotive assembly plant operated multiple S5-115U controllers managing conveyor systems, robotic welding cells, and material handling equipment. As production demands increased, the facility needed to control dozens of additional solenoid valves and indicator lamps. By deploying the Siemens 6ES5441-7LA12 across their PLC racks, the plant added 32 outputs per slot, achieving the required I/O capacity without expanding cabinet footprints. The Siemens 6ES5441-7LA12 provided the high-density, reliable output solution that kept the assembly line running at peak throughput.

The Siemens 6ES5441-7LA12 is the go-to choice for controlling up to 32 loads per module: solenoid valves, motor contactors, signal lamps, relay coils, and small actuators. Its 0.5A per channel capacity is sufficient for most standard industrial loads, while the total current limit of 4A per common group ensures safe operation. For applications requiring channel isolation, Siemens offers the floating 451 series modules as alternatives . The Siemens 6ES5441-7LA12 excels in systems where all outputs share a single 24V power supply—the most common configuration in industrial control panels.
