Available. The Mitsubishi QY18A is a digital output module from the MELSEC-Q Series, designed for use in industrial automation systems. This module provides 8 independent relay outputs, each capable of handling 24 V DC at 2 A for resistive loads and 240 V AC at 2 A (cos φ = 1). The module operates with a supply voltage of 12-24 V DC and occupies 16 I/O points on the PLC. It features a relay isolation method and has a response time of 10 ms or less for OFF to ON and 12 ms or less for ON to OFF transitions. The QY18A is rated for a mechanical life of over 20 million cycles and an electrical life of over 100,000 cycles under rated conditions. It has a maximum switching frequency of 3,600 cycles per hour and operates within a temperature range of 0°C to 55°C. The module measures 98 mm in height, 27.4 mm in width, and 90 mm in depth, with a weight of 0.22 kg. It is suitable for applications requiring reliable and efficient digital output control in automation systems.
