This Allen-Bradley 1794-OB16D provides a critical diagnostic advantage for your control system. It actively detects open circuits and shorted field wiring faults. This module reports these faults instantly to your controller. That capability drastically cuts your troubleshooting downtime.
The product 1794-OB16D sources 16 non-isolated digital outputs for versatile control. Each channel delivers a maximum of 500mA continuously. The entire module supports a total output current of 8.0A. Your system gains reliable actuation for various loads.
You get a nominal output voltage of 24V DC for standard industrial operations. The operating voltage range spans from 10V to 31.2V DC. This flexibility accommodates different power supply conditions easily. The module only draws 60mA from the 5V DC FlexBus backplane. Its maximum power dissipation is just 4.8W at 31.2V DC.
Product Procurement & Buyer Guide
The diagnostics feature directly reduces your operational expenses. When a field device fails, the module identifies the exact channel. You do not need to guess which wire is faulty. This saves hours of manual inspection work. Production lines return to service much faster.
Compatibility is simple with the 1794 Flex I/O platform. This module works perfectly with the 1794-TB3 terminal base unit. It also fits the 1794-TB3S and 1794-TBKD bases. You can install or remove this module under power. You avoid costly system restarts during maintenance.
Procurement managers value the module’s robust electrical specifications. The on-state current per channel reaches 500mA for strong signal drive. The off-state leakage stays below 0.5mA to prevent false triggering. Output signal delay measures only 0.5 ms for fast response. This ensures precise control of your actuators.
Application engineers appreciate the simple DIN rail mounting. You snap the terminal base onto the rail first. Then you insert the 1794-OB16D module into the base. The 16 yellow LEDs show the status of each output channel. You can diagnose issues instantly from a distance.
The module supports multiple network communication options. You can use ControlNet, DeviceNet, or EtherNet/IP protocols. It also works with Universal Remote I/O networks. This wide compatibility fits your existing architecture.
For harsh environments, choose the XT version of this module. The XT variant operates reliably in extreme conditions. This reduces your overall panel and maintenance costs significantly.
