Siemens LOGO 24RCEO — 6ED10522HB080BA1
Engineering Verification Checklist
- Confirm 24 VDC supply voltage matches branch design
- Verify relay output rating suits connected load (resistive vs inductive)
- Check 8 digital inputs are compatible with field sensors (sourcing/sinking)
- Validate Ethernet communication settings for host system integration
- Confirm DIN rail clearance for derating at elevated ambient temperature (55 °C ceiling)
- Verify CE, CSA, FM, UL certifications meet project jurisdiction requirements
- Review required approvals against end-use environment (no CSA or FM if not needed)
- Assess expansion needs — base unit is non-expandable per catalog record
- Confirm 400-block program memory satisfies application complexity
Overview
The 6ED10522HB080BA1 is the LOGO 24RCEO — a standalone, self-contained programmable logic controller from Siemens. The MPN prefix 6ED1 designates the LOGO! series; the HB segment indicates the relay-output variant operating from 24 VDC. It delivers 8 digital inputs, 4 relay outputs, Ethernet connectivity, and 400-blocks of program memory in a box-style enclosure.
Key distinctions from catalog peers: the primary part carries CE, CSA, FM, and UL multi-agency approval and is packaged as an individual unit (Box) rather than bulk.

Output Stage — Relay Considerations
The 4 relay outputs are electromechanical contacts. Selecting this output type trades solid-state switching speed and silence for higher contact ratings on resistive and inductive loads. For motor loads, coordination with downstream overload or short-circuit protective devices follows general panel practice. The exact contact ratings are not listed in the catalog record; specification sheets for the LOGO! series should be consulted for voltage and current limits per contact.

Why 6ED10522CC080BA1 (Similarity 0.92)
Matches the primary part on brand, series, display type, mounting, encapsulation, communications, approvals, and temperature range. The output type differs: solid-state (SSRs) rather than relay contacts. The "CEO" designation versus "RCEO" indicates the solid-state output variant.
Why 6ED10521HB080BA1 (Similarity 0.88)
Shares the same LOGO 24 RCE base designation with the primary unit, matching mounting, encapsulation, Ethernet, temperature, and I/O counts. Approvals lack FM; the record shows CE, CSA, UL only. Minor model-year generation difference in MPN suffix (052 vs 052 in primary; 0521 vs 0522 prefix segment).
Why 6ED10573BA030AA8 (Similarity 0.84)
Shares series, display, mounting, Ethernet, approvals, temperature, and I/O type/count. This is a starter kit with bulk packaging and expandable architecture versus the standalone base unit — not a direct replacement for the primary part.
FAQ
What is the operating voltage of 6ED10522HB080BA1? The LOGO 24RCEO variant operates at 24 VDC per its model designation. Confirm the exact supply range and input current draw from Siemens LOGO! documentation.
Can 6ED10522HB080BA1 drive inductive loads such as motor contactors? The relay outputs are electromechanical contacts rated for resistive and limited inductive loads. The exact contact ratings (voltage, current, horsepower) are not listed in this catalog record.
How does the 6ED10522HB080BA1 compare to the solid-state variant 6ED10522CC080BA1? Both share identical form factor, I/O counts, communications, approvals, and temperature range. The primary difference is output type: relay contacts (6ED10522HB080BA1) versus solid-state switching (6ED10522CC080BA1).
