The Allen-Bradley 1771-OW is a versatile selectable relay output module designed for seamless integration with industrial automation systems. It features eight relay output channels grouped into four sets, each equipped with individual commons, allowing for flexibility in configuration between Normally Open (N.O.) and Normally Closed (N.C.) contacts, with N.O. as the default setting. Ideal for resistive loads, this module offers robust internal electrical isolation from module logic, supports simultaneous activation of all relay channels, and accommodates continuous current of up to 1 Amp per output. Operating efficiently with a voltage range of 24-138V AC or 24-125V DC, the 1771-OW supports 0.25A at 120V AC/DC and is housed within a system powered via the backplane, requiring a current of up to 700mA. Its performance is further defined by an operating temperature range of 0-60°C, a storage range of -40 to 85°C, and a thermal dissipation up to 12.6 BTU/hr, ensuring reliable function under various environmental conditions.
