Overview
Key Features
- 32 solid-state DC sourcing output points.
- 24 VDC nominal output voltage.
- Operating voltage range of 20.4 to 26.4 VDC.
- Maximum surge current of 2.0 A.
- Maximum bus current draw of 300 mA at 5 VDC.
- Maximum off-state leakage of 1.0 mA at 26.4 VDC.
Output Configuration
The 1769-OB32 provides 32 discrete DC output channels. As a sourcing output module, it supplies positive DC voltage to the connected load when an output channel is energized. The external load returns current through its DC common connection.
Meanwhile, the solid-state output design uses electronic switching rather than mechanical relay contacts. Therefore, the module is intended for DC load control rather than direct AC output switching.
Electrical Characteristics
The module operates within a 20.4 to 26.4 VDC supply range. Its maximum on-state voltage drop is 1.0 VDC at 1.0 A, which is an important consideration when checking the voltage available at the connected load.
Furthermore, the maximum off-state leakage current is 1.0 mA at 26.4 VDC. In addition, the maximum surge current is 2.0 A. These values should be considered when selecting connected devices and checking their electrical requirements.
