Integrated Electronic Overcurrent Protection and Deterministic Execution
The 1769-OB16P features built-in electronic short-circuit and thermal overcurrent protection for each output point, safeguarding internal solid-state switches and field wiring from temporary line faults or inductive surges without requiring external fuses. The module processes fast ON/OFF switching times (1.0 ms ON, 2.0 ms OFF) to maintain deterministic performance and precise control synchronization over the 1769 backplane bus in high-speed machinery environments.
Frequently Asked Questions
Q: What is the primary difference between the 1769-OB16 and the 1769-OB16P?
A: The "P" suffix denotes built-in electronic overcurrent and short-circuit protection, as well as higher point current capability (up to 1.0 A per point at 30 °C compared to 0.5 A max on standard 1769-OB16).
Q: Which removable terminal block is required for field wiring connection?
A: The 1769-OB16P utilizes the 18-pin 1769-RTB18 Removable Terminal Block kit.
Q: Can the 1769-OB16P module be located more than 8 slots away from the power supply?
A: No. The power supply distance rating is 8 modules. To place output modules further along the bank, an expansion power supply (such as the 1769-PA2, 1769-PB2, 1769-PA4, or 1769-PB4) must be installed.
Field Installation Guidelines
- Mount the module onto a 35 mm DIN rail or directly to a panel backplate using M4 screws. Ensure the DIN rail is bonded to functional earth (FE).
- Install the module within 8 slot positions of the primary system power supply or an expansion power supply.
- Completely de-energize the 24V DC field supply and system backplane power prior to attaching or removing the 1769-RTB18 terminal block.
- Wire field output loads using 22 to 14 AWG solid or 22 to 16 AWG stranded copper wire, maintaining tight, secure terminal connections (torque to 0.68 Nm / 6 in-lbs).
- Fasten the module lock levers securely to ensure proper 1769 backplane bus continuity before restoring power to the assembly.
