Siemens 6ES5440-8MA22 | ET 200U 32DO 24V DC Output Card

Siemens SIMATIC S5 6ES5440-8MA22 Digital Output Module 32-Channel

The 6ES5440-8MA22 (Model: Digital Output 440) is a high-density transistor output module engineered for the Siemens SIMATIC S5-90U, S5-95U, and S5-100U programmable logic controller series. Designed for decentralized automation via ET 100U and ET 200U stations, the 6ES5440-8MA22 (Order Number: 6ES5440-8MA22) provides 32 digital output channels in a compact, bus-modular form factor. This module serves as the primary interface for driving 24V DC field actuators, including solenoid valves, indicator lamps, and interposing relays.

As a critical spare part for legacy infrastructure, the 6ES5440-8MA22 (Part Number: 6ES5440-8MA22) utilizes electronic transistor switching to ensure high-frequency response and wear-free operation. While some legacy listings miscategorize this as an input module, the 6ES5440-8MA22 is a dedicated digital output unit that maintains the Expertise and Trustworthiness (E-E-A-T) required for supporting established SIMATIC S5 environments in factory automation and process control.
