The Siemens 6ES7138-4CA01-0AA0 is a compact PLC I/O module designed for distributed automation applications. It operates on 24 V DC and is commonly installed in control cabinets where space is limited but reliable signal handling is still required. This module is used to expand I/O capability close to the machine or process, reducing wiring complexity and improving response time.
With dimensions of 81 × 15 × 52 mm, this module is narrow and space-efficient. It mounts easily alongside other I/O modules on the same base or rail, making it suitable for compact panels and decentralised installations.
