Product Description
The Mitsubishi Electric A1SY50 is a 16-point transistor (sink type) output module designed for use with the MELSEC-A Series programmable controller systems. It uses photocoupler isolation between the PLC backplane and the output field devices, and supports a rated load voltage of 12/24 VDC with a maximum load current of 0.5 A per point and 2 A per common. The module connects via an 18-point screw terminal block and features LED indicators to show the ON state of each output point.
