FAQ

Questions Buyers Ask Most

What distinguishes 6ES7288-1CR40-0AA0 from the CR40s version?

6ES7288-1CR40-0AA0 is the earlier CPU CR40 ordering variant; verify firmware and project compatibility instead of assuming a CR40s unit is a drop-in replacement.

What onboard I/O does 6ES7288-1CR40-0AA0 provide?

6ES7288-1CR40-0AA0 provides 24 digital inputs and 16 relay outputs, for 40 fixed onboard digital points.

What are the enclosure and power requirements for 6ES7288-1CR40-0AA0?

6ES7288-1CR40-0AA0 uses an 85–264 V AC line supply and a 24 V DC input circuit; allow approximately 125 × 100 × 81 mm and about 18 W power loss.

How much working memory is available in 6ES7288-1CR40-0AA0?

6ES7288-1CR40-0AA0 provides 12 KB program memory and 8 KB data memory, with up to 2 KB of retentive memory for selected data.

What high-speed counting is supported by 6ES7288-1CR40-0AA0?

6ES7288-1CR40-0AA0 supports four single-phase high-speed counters up to 100 kHz or two A/B-phase counters up to 50 kHz, subject to the configured input assignment.

Can additional signal modules be fitted to 6ES7288-1CR40-0AA0?

6ES7288-1CR40-0AA0 is compact and non-expandable, with no signal-module or signal-board expansion; select another CPU if the final design exceeds 24 DI and 16 relay outputs.

Which checks are essential before ordering 6ES7288-1CR40-0AA0?

For 6ES7288-1CR40-0AA0, send the exact nameplate, firmware, supply, I/O allocation, relay inrush data, RS485 settings, program backup, quantity and destination.
