Product questions
What are the A1S-Y41 output type and current limits?
The A1S-Y41, also written A1SY41, has 32 sink-type transistor outputs sharing one common. The maximum load current is 0.1 A per output and 2 A per common; check both limits when selecting loads.
What voltage and response time does the A1S-Y41 support?
The rated load voltage is 12/24 V DC, with a 10.2–30 V DC operating load range. OFF-to-ON response is at most 2 ms; ON-to-OFF is at most 2 ms with a resistive load.
What connector does the A1S-Y41 use?
The A1S-Y41 uses a 40-pin connector for external wiring. Verify the connector and pin assignment against the equipment documentation before ordering or connecting it.
What does the A1S-Y41 error LED indicate?
Mitsubishi specifies that the ERR LED lights if the 3.2 A common fuse blows, but it can also light if the external power supply is off. The fuse is not replaceable.
