Mounting & wiring notes
Snaps onto 35 mm DIN rail, 4 spacing units wide. The 12/24 VDC supply is OK between 10.8 and 28.8 V — typical 24 V panel supply works. Outputs are relay contacts with a shared common? (the spec doesn't break out per-terminal, but standard LOGO! relay blocks have separate commons per output pair). External fusing is mandatory — no internal short-circuit protection. For inductive loads, stay at or under 3 A; resistive loads can go to 10 A. The 400-block memory is function-specific, meaning your program size limit depends on how many instructions each block eats—allow headroom for averages. Program transfer via Ethernet or the microSD slot; compatible with LOGO! Soft Comfort V8 and newer.
