- Description 1762-OB16 A-B MicroLogix 16-Point 24V DC Output Module Product Dimensions： Product Description (Detailed Explanation) The 1762-OB16 provides 16 digital outputs in a compact, modular form factor. It is a Sourcing (Source) type module, meaning that when an output is energized, the module “sources” or supplies positive voltage from the VDC user supply to the connected field device. The module connects to the right side of a MicroLogix controller or a previous I/O module via an integrated high-speed bus ribbon cable. It features a removable terminal block with a finger-safe cover, allowing for easy wiring and maintenance without disturbing the rest of the PLC rack. Product Parameters (Technical Specifications) Parameter Category Specification Number of Outputs 16 Points Output Type Solid-State Transistor (Source) Operating Voltage Range 20.4V to 26.4V DC Backplane Current (5V DC) 175 mA (Maximum) Backplane Current (24V DC) 0 mA Continuous Current per Point 0.5 A @ 30°C / 0.25 A @ 55°C Continuous Current per Module 8.0 A @ 30°C / 4.0 A @ 55°C Signal Delay (Off to On) 0.1 ms Signal Delay (On to Off) 1.0 ms Product Advantages (Key Benefits) High Density: Provides 16 channels in a very slim footprint, saving valuable space in small control cabinets. High-Speed Switching: Because it uses transistor technology rather than mechanical relays, it can handle high-frequency switching tasks with millisecond response times. Enhanced Reliability: No moving internal parts mean the module is not subject to mechanical wear and tear, making it ideal for applications with frequent cycling. Easy Expansion: The flat ribbon cable design allows for quick “plug-and-play” expansion without the need for separate backplane hardware. Visual Diagnostics: Features a clear LED display panel on the front, providing real-time status indication for each of the 16 output channels. Precautions (Important Notes) No Hot Swapping: Power to the PLC and the expansion bus must be turned OFF before connecting or disconnecting the module. Failure to do so can result in permanent damage to the controller’s I/O bus. Inductive Load Protection: When driving inductive loads (such as solenoid valves or DC contactors), it is highly recommended to use an external surge suppressor (e.g., a 1N4004 diode) to protect the transistor from voltage spikes. Thermal Derating: The current capacity of the module halves as the temperature rises from 30°C to 55°C. Ensure proper enclosure ventilation to maintain rated performance. Common Terminal Limitation: All 16 points share a common power source. Ensure that the total current load does not exceed the 8.0A module limit. Product Applications (Typical Use Cases) Packaging Machinery: Controlling fast-acting pneumatic solenoids for sorting, pushing, or labeling. Small Assembly Cells: Driving 24V DC pilot lights, buzzers, and small DC relays on operator consoles. Material Handling: Managing divert arms and gate actuators on high-speed conveyor systems. HVAC Control: Actuating dampers and small DC fans in building automation units where silent operation (no relay clicking) is preferred.
