1756-OB16D | Allen-Bradley ControlLogix 19-30VDC Diagnostic Output Module 16-Point

The 1756-OB16D is a 16-point digital output module for the ControlLogix series of programmable automation controllers (PACs). It is used to provide 16 individual 24V DC output channels for controlling devices such as solenoids, lights, or relays in industrial automation systems. This module is typically used in applications that require controlling discrete outputs in a precise manner.

The 1756-OB16D module is capable of controlling 24V DC loads, such as solenoids, lights, or relays. The module provides sourcing outputs, which means it supplies current to the connected load. The current ratings and maximum load specifications for each channel can be found in the product manual, but typically each output can provide up to 2A per channel.

The 1756-OB16D is designed for use in general industrial environments. If you need to use it in a hazardous location, you will need to verify whether it meets the necessary certifications for hazardous environments (such as ATEX or UL ratings). For specific hazardous environment applications, Allen-Bradley offers other modules that may be better suited.

The 1756-OB16D module is designed for 24V DC outputs. The input power for the module should be supplied from a reliable 24V DC source, and the module can control 24V DC output devices.

To wire the 1756-OB16D module, connect the 24V DC power supply to the V+ and V- terminals (V+ for positive, V- for negative). Then, connect your output devices, such as relays or solenoids, to the output terminals (1 to 16), with the positive terminal of the device connected to the output terminal and the negative terminal of the device connected to the V- (common) terminal. Each output terminal provides 24V DC to the connected load when activated, and each output can supply up to 2A of current. Ensure that your load's current rating does not exceed the output module's limits, and always follow proper grounding and wiring practices.
