A1SY81

The Mitsubishi A1SY81 is a digital output module from the MELSEC AnS/QnAS series designed to control industrial processes efficiently. This module features transistor outputs and offers 32 output points with a common terminal arrangement. This device has a load voltage rating of 12/24 VDC. The A1SY81 digital output module has a maximum load current of 0.1 amperes per point, or 2 amperes per common terminal, and a maximum allowed rush current of 0.4 amperes for 10 milliseconds or less. It exhibits minimal leakage current at the OFF circuit, with values of 0.1 mA or less, ensuring accurate control. For added safety, the module is equipped with a Zener diode surge absorber with a fuse rating of 3.2 A and a breaking capacity of 50 A. The integrated error display with LED indication notifies users when a fuse blows, enabling prompt troubleshooting. The A1SY81 also features ON-state indicators through LEDs, providing visual feedback on its operating status. The module is conveniently connected via a 37-pin D-sub-connector, supporting a wire size of 0.3 mm². Its external power supply operates at 12/24 VDC (10.2 to 30 VDC) and typically consumes 8 mA at 24 VDC for common terminal supply. The internal current consumption at 5 VDC is approximately 500 mA when all points are ON. With dimensions of 9.36 cm x 3.45 cm x 13 cm and a weight of 0.23 kg, the A1SY81 is space-efficient and easy to install in various setups. The module ensures safe operation through photocoupler isolation between output terminals and PC power for all modules, safeguarding the equipment from electrical interference and damage.
