Get now: Allen-Bradley 1769-OB16P Protected Digital Output Module
Atlantechdrives provides you the 1769-OB16P, a 16-point 24V DC sourcing output module with integrated electronic protection. The «P» in the part number stands for «Protected,» signifying that this module features onboard short-circuit and over-current protection, making it the safest choice for complex DC control circuits.
- Outputs: 16 Sourcing DC Outputs (Protected)
- Voltage: 24V DC (20.4V to 26.4V range)
- Current Rating: 0.5A per point / 8.0A per module
- Protection: Short-circuit and Thermal Overload
- Backplane Current: 160 mA @ 5.1V
- Isolation: 30V continuous
Technical Superiority: Electronic Short-Circuit Protection (ESCP)
Secure now the 1769-OB16P to eliminate the risk of hardware failure due to field wiring errors. The technical highlight of the 1769-OB16P is its ability to electronically detect a short circuit or an overload condition on an individual point. When a fault occurs, the module automatically shuts down the affected output to prevent the internal transistors from burning out. This is a massive advantage over standard OB16 modules, which often require expensive external fuses or risk total module failure during a wiring incident. The 1769-OB16P also features «Thermal Shutdown» protection, which monitors the internal temperature of the output drivers. When you procure this module, you are investing in an intelligent I/O layer that provides superior diagnostics and reduces system downtime through its self-protecting architecture.
Installation Advice: Resetting Faulted Outputs
When installing the 1769-OB16P, it is important to know that once an electronic protection trip occurs, the output remains OFF until the fault is cleared and the module is reset. You can reset the protection by cycling the output tag in the PLC software or by cycling the 24V DC field power. Ensure that your field power supply has enough «headroom» to handle the module’s 8.0A total capacity. Use high-quality DC common wiring to ensure the protection circuitry has a stable reference for current sensing. Sourcing your 1769-OB16P from Atlantechdrives ensures you receive a unit with fully functional protection logic, ready to safeguard your automation assets.
Maintenance and Diagnostic Intelligence
The 1769-OB16P provides detailed diagnostics to the controller. Beyond the 16 amber status LEDs, the module reports «Electronic Protection» status bits. Maintenance teams can monitor these bits in the Studio 5000 environment to identify exactly which field device is causing an over-current issue. This proactive diagnostic capability is what sets the «P» series apart. Sourcing from Atlantechdrives ensures you receive an authentic module with the original high-speed sourcing transistors, providing clean 24V DC pulses for your actuators and valves.
FAQs
Q: What is the difference between OB16 and OB16P?
A: The OB16P includes internal electronic short-circuit protection, whereas the standard OB16 requires external fusing.
Q: Is this a Sinking or Sourcing module?
A: It is a Sourcing module (PNP), meaning it provides 24V DC (+) to the load.
