Siemens AG 6ES5 482-8MA13 Digital Input Module

Siemens 6ES5 482-8MA13 SIMATIC S5 Digital Input/Output Module is a non-floating, 32-channel digital I/O card for legacy S5 controllers, delivering 16 inputs and 16 outputs at 24 V DC with a per-channel rating of 0.5 A. It uses a 40-pin snap-in connector system and is designed to mount in SIMATIC S5 racks with compatible connectors, making it a common spare part for S5-90U, S5-95U, and S5-100U configurations and for ET 100U or ET 200U expansion setups. A front LED display provides status indicators for the input and output sections to aid on-site diagnostics, while the module’s straightforward wiring supports direct interfacing of 24 V sensors, switches, relays, and small actuators within compact automation layouts. This 482-8MA13 variant is widely referenced as a 32-channel digital I/O solution for older Siemens systems, aligning with typical applications in digital control, basic signaling, and interlock circuits where space efficiency and quick diagnostics are essential.
