Product Description
The Mitsubishi Electric A1SY50 is a 16-point transistor (sink type) digital output module designed for use in the MELSEC-AnS series programmable controller systems. It provides photocoupler-based isolation between the PLC's internal logic and external load circuits, supporting rated load voltages of 12 VDC or 24 VDC and a maximum load current of 0.5 A per point (2 A per common). The module connects to field devices via a screw terminal block and features LED output status indicators for each channel.
