Performance and Application Benefits
The 6ES5482-3BA11 combines 16 inputs and 16 high-current outputs in a single module, saving valuable rack space in S5 automation systems. Moreover, the 2.0 A per channel output capability allows direct driving of relays, contactors, and small motors without external interposing devices. In addition, the optical isolation protects the CPU from electrical noise and voltage surges on both field inputs and outputs. Consequently, the built-in filtering on inputs eliminates contact bounce from mechanical switches, preventing false triggers. Furthermore, the output channels include short-circuit and thermal protection for enhanced reliability. Therefore, this module is well-suited for compact control applications requiring high-current outputs, including small conveyor systems, packaging machines, and hydraulic control panels.
