Siemens 6ES7441-2AA05-0AE0 SIMATIC S7-400 CP 441-2 2-Channel Point-to-Point Comm Module

The Siemens 6ES7441-2AA05-0AE0 is a SIMATIC S7-400 CP 441-2 coupling module for point-to-point connections, with 2 variable interfaces each configurable as 20 mA TTY, RS 422/485, or RS 232 at up to 115.2 kbit/s. It adds the RK 512 protocol driver on top of 3964(R), ASCII, and printer support, letting two independent serial links run from one module slot.

Technical Specifications

Selection Notes

Choose the CP 441-2 over the single-interface variant in the same family when the application needs two independent point-to-point links, or specifically the RK 512 protocol, on one module slot rather than dedicating two slots to single-channel modules. Each of its two interfaces is separately variable between TTY, RS 422/485, and RS 232, so the two links do not have to share the same electrical standard.

Applications

Two independently configurable serial channels with 3964(R), ASCII, RK 512, and printer protocol support suit racks that must talk to two separate third-party serial devices, such as a host computer over RK 512 and a report printer, from a single S7-400 slot.
