The Allen-Bradley 1771-OW is a versatile selectable relay output module designed for industrial applications, featuring eight relay output channels organized into four groups. It allows for each channel to operate either as Normally Open or Normally Closed, with Normally Open as the default setting, making it suitable for managing different types of loads, particularly resistive loads. With a maximum continuous current capacity of 1.0 ampere per channel and operating voltage range of 24-138V AC or 24-125V DC, this module ensures reliable performance. Its robust design includes internal electrical isolation and compatibility with backplane power supply, necessitating only 700 mA of backplane current, and it maintains efficient energy use with thermal dissipation ranging from 11.3 to 12.6 BTU/hr.
