Eight-channel marshalled termination assembly for redundant ET 200M analog input wiring.
Siemens 6ES7650-1AA51-2XX0 is an eight-channel analog input marshalled termination assembly for the ET 200M analog input module 6ES7331-7NF00-0AB0, E-Stand 5 or higher. It supports 1–5 V and 0/4–20 mA field signals with redundant module connection.
The anthracite-gray housing is the later design; Siemens states that its function is the same as 6ES7650-1AA50-2XX0. Redundant power inputs, channel fuses, power LEDs, shield connections, pluggable field terminals and per-channel HART handheld access simplify cabinet marshalling and maintenance.

Terminate and protect eight analog field channels in PCS 7 and ET 200M cabinets.
Support redundant power and dual I/O-module connection for higher-availability input architectures.
Siemens SiePortal identifies 6ES7650-1AA51-2XX0 with the lifecycle wording End Prod.Lifecycl. and names 6ES7650-1AA52-2XX0 as the successor type. The successor must be checked against the installed I/O module, cabinet dimensions, connectors, signal ranges and wiring before migration.
Siemens specifies 6ES7331-7NF00-0AB0 at E-Stand 5 or higher.
The documented signal ranges are 1–5 V and 0/4–20 mA.
Yes. It provides redundant power inputs and dual connectors for redundant I/O-module operation.
Each channel uses a 0.5 A fast fuse as standard; Siemens also documents an optional 1.5 A fast fuse.
Yes. The assembly provides HART handheld terminal connectivity for each channel.
Verify the exact order code, companion module revision, jumper positions, fuse ratings, supply feeds, terminal wiring and cabinet footprint.
