Siemens 6ES7141-5AH00-0BA0 SIMATIC ET 200AL DI 16x24VDC 8xM12 IP67 Remote I/O Module

The Siemens 6ES7141-5AH00-0BA0 is a SIMATIC ET 200AL digital input module with 16 sink-type 24 V DC channels wired through 8 M12 connectors, built for IP65/67 machine-mounted installation without a control cabinet. It draws 30 mA quiescent current, supplies up to 1.4 A total to its 8 encoder outputs, and operates from -30 to 55 C.

Selection Notes

The 16-channel, 8x M12 count over the 8-channel sibling doubles sensor density on the same IP67 housing depth, so it is the pick when a machine zone needs more than 8 digital sensors within one drop-cable run. Support for safety-related tripping of standard modules from FS01 (PLd / Cat. 3 / SIL 2) lets it feed a fail-safe F-CPU logic function without a dedicated F-module when PLd or SIL 2 is sufficient. The -30 to 55 C range and up to 5000 m altitude rating match the smaller-channel variant, so mixing both on one machine does not change the environmental envelope.
