Description
The Allen-Bradley 1771-OQ16 is a 1771 16-point 24V DC digital output module for driving solenoids, relays, and indicators in PLC-5 systems. Digital output modules switch field devices such as solenoids, relays, contactors and indicator lights on and off when the controller commands it. 1771 Universal I/O is the chassis-based I/O family used with Allen-Bradley PLC-5 processors and remote I/O adapters. Although it is a legacy platform, it remains installed in many plants and depends on replacement modules to stay running. The 1771-OQ16 is typically used for solenoid, relay & indicator control.
Key ratings for the 1771-OQ16: 16 Points, 24V DC. It connects through 1771 field wiring arm / chassis backplane and is compatible with the Allen-Bradley 1771 I/O Chassis / PLC-5 system. Because it matches the original catalog number, it can be dropped into an existing 1771 Universal I/O / PLC-5 installation as a direct replacement, or added to expand the system. TCI stocks the 1771-OQ16 in New, Surplus and Used condition, and each condition is priced separately.
