The 1771-OQC output module is a digital output module that has been released in the Allen-Bradley 1771 product line of digital output devices. This module has been designed, manufactured, and distributed by Allen-Bradley/Rockwell Automation and the main objective of this module is to control whether a DC-powered device is powered on or off. This module has 8 outputs that are distributed in 4 groups of 2 inputs each. The Allen-Bradley 1771-OQC digital output module has a voltage rating of 24 Volts DC with a tolerance of +10 percent to -15 percent, and the peaks of modulated ripple must range between 17 and 34 Volts DC. The 1771-OQC digital output module has a maximum output current of 2.25 Amps per output and group and 9 Amps per module and a maximum surge current of 4 Amps during 10 milliseconds per output.

The Allen-Bradley 1771-OQC digital output module has a power dissipation of 19.1 Watts maximum and 1.1 Watts minimum and a thermal dissipation of 65.1 BTU per hour. The recommended environmental conditions for this module are a relative humidity range of 5 to 95 percent without condensation and a temperature range of 0 to 60 degrees Celsius. The Allen-Bradley 1771-OQC digital output module includes internal clamping diodes that protect the output transistors from high voltage transients, and this feature is known as surge suppression. When connected to relays, solenoids, motor starters, and motors, it is important to use an additional suppression device. The module does not include any kind of enclosure and that is why it should only be installed in indoor environments.
