The Allen-Bradley 1756-OW16I is a ControlLogix discrete output module that provides sixteen (16) individually isolated, normally open (N.O.) relay contact outputs. Each output channel supports an operating voltage range of 5–125 VDC and 10–240 VAC. The module delivers output current ratings of 1 A at 5–30 VDC, 0.5 A at 48 VDC, 0.22 A at 125 VDC, 1.5 A at 120 VAC (50/60 Hz), and 0.75 A at 240 VAC (50/60 Hz). The 1756-OW16I is designed to offer reliable switching performance and electrical isolation, making it suitable for controlling various DC and AC loads in industrial automation systems.
