Product questions
Is the A1S-Y22 a relay or triac output module?
It is a 16-point triac output module, not a relay output module. Mitsubishi documentation identifies it as A1SY22; A1S-Y22 is also used as a part-number spelling.
What load voltage and current can the A1S-Y22 switch?
The rated load voltage is 100–240 V AC at 50/60 Hz. The maximum load current is 0.6 A per point and 2.4 A per common; eight outputs share each common. Check the load and the applicable limits before selection.
How are the A1S-Y22 outputs connected?
The module has a 20-point screw terminal block with M3.5 screws and eight output points per common. Verify the terminal assignment against the applicable Mitsubishi manual before wiring.
What does the A1S-Y22 error indicator mean?
Mitsubishi states that the ERR indicator illuminates if a fuse is blown or the external supply is lost. Each common has a non-replaceable 5 A fuse. The indicator alone does not establish which condition caused the fault.
