Overview
Output Configuration and Switching
The module provides 16 normally open relay outputs, divided into two groups of eight points. Each relay operates as an individual switching contact, allowing the controller to manage multiple external loads through discrete output signals.
In addition, the relay contacts support both AC and DC switching applications. The specified operating voltage ranges are 5 to 265 V AC and 5 to 125 V DC. Therefore, users should check the connected load requirements and contact ratings before selecting the module for a particular circuit.
Electrical and Installation Characteristics
The 1769-OW16 draws backplane current from both the 5.1 V and 24 V supply buses. Its power-supply distance rating is eight modules, which is an important consideration when arranging the module within a CompactLogix system.
Meanwhile, the open-style enclosure supports installation inside a suitable control cabinet. The module can be mounted on a DIN rail or panel and operates within an ambient temperature range of 0 to 60 deg C.
