Siemens 6ES7142-4BF00-0AA0 Central Processing Unit Module

Siemens 6ES7142-4BF00-0AA0 is an ET 200 PRO digital output module offering eight 24 V DC output channels rated up to 0.5 A per channel, designed to switch field devices in SIMATIC ET 200 PRO installations. The unit ships with a bus module and is intended for use within the ET 200 PRO I/O system; the required IO connection module (6ES7194-4..00-0AA0) must be ordered separately to complete the assembly. It includes module diagnostics to monitor output status and fault conditions, helping with maintenance and fault isolation in automation lines. The module operates on 24 V DC and is listed in product listings as IP65-rated in certain configurations, enabling use in harsher environments when installed with appropriate enclosures. Typical applications include remote digital output control in automated machinery, process lines, and packaging equipment where reliable 24 V DC actuation of loads such as solenoids, relays, or indicator devices is needed within an ET 200 PRO system.
