Mitsubishi Electric A1SY60 Relay Output Module

The Mitsubishi Electric A1SY60 Relay Output Module is a 16-channel relay output expansion for Mitsubishi A1S PLC systems, enabling reliable control of external devices in industrial automation. Each channel switches up to 2 A at 250 VAC (48 W maximum per channel) through SPDT relays with AgSnO2 contacts, driven by a 24 VDC input. The module supports direct connection to Mitsubishi A1S series PLCs and can be mounted on DIN rails or panels, with IP20 protection on the mounting side and an operating range of 0°C to 55°C. Common replacements include Siemens 6ES7 321-1BL00-0AA0, and its typical applications include factory automation, production lines, assembly machines, and material handling systems that require reliable relay control of solenoids, motors, and signal lights.
