Specialist brandAnswers below use Siemens official product documentation for this exact order number.
No. -0AA0 is CPU CR40; CPU CR40s uses 6ES7288-1CR40-0AA1. Verify the suffix on the installed device.
It has 24 digital inputs and 16 relay digital outputs.
No. Siemens lists no I/O-module or signal-board extension for CPU CR40.
The Siemens catalogue lists up to 10 KB retentive memory, alongside 12 KB program and 8 KB data memory.
The documented contact range is 5–30 V DC or 5–250 V AC, with a 2 A rating per point.
No pulse output is specified for the relay-output economy CPU.
Use the complete order number on the nameplate and verify firmware, communication and project requirements before substitution.
