Product questions
What type of outputs does the A1S-Y42P provide?
It is a MELSEC-A transistor output module with 64 sink-type outputs, arranged as 32 points per common. It occupies 64 output I/O points.
What voltage and load current can the A1S-Y42P handle?
The rated load voltage is 12 or 24 V DC. Mitsubishi specifies a maximum load current of 0.1 A per output and 2 A per common. The 14 mA figure is typical external supply current per common at 24 V DC, not the output load rating.
How are the outputs connected and monitored on the A1S-Y42P?
External wiring connects through two 40-pin connectors. The module has ON indicator LEDs, with a switch selecting which group of 32 points is displayed.
Does the A1S-Y42P have a fuse or output protection?
The A1SY42P has no fuse. Mitsubishi describes thermal and short-circuit protection; assess the complete installation and its required external protection separately.
