Industrial 8573A-6501 Low Leakage Output Device

The OPCON 8573A-6501 Low Leakage Output Device provides optically isolated SPST normally open TRIAC switching for 230 VAC loads, enabling reliable control of low-current AC circuits in industrial photoelectric sensing and automation systems. It accepts 8–20 VDC input (9.5–20 mA) and delivers up to 0.5 A at 230 VAC with an on-state voltage drop under 1.7 V and an off-state leakage current up to 1.5 mA at 120 VAC, supporting peak surge currents to 6 A. This low leakage design favors precise switching with PLC-based control, making it suitable for machine panels, conveyors, packaging or material handling equipment, and OEM machine controls, and it is commonly used as a replacement for OPCON 8572A-6501, 8563A-6501, or 8530A-6501 in industrial automation installations.
