Designed for decentralized drive systems, the Allen Bradley 1771-OBN provides 16 isolated 120V channels to block load‑side electrical feedback and protect the control system. Its direct 1771 backplane connection eliminates complex external wiring, while maintaining stable triggering in noisy legacy production environments. Wholesale procurement has been completed with suppliers through Hanyite Automation Technology, and all brand‑new units are in stock for fast integration and reliable performance in PLC‑5 system upgrades.
| Output points: | 16 independent isolated channels |
| Electrical specifications: | Rated working voltage of 120V AC |
| Backplane interface: | Standard 1771 I/O bus direct connection terminals |
| Status indication: | Dense configuration of LED fault feedback lights on the front panel |
| Wiring configuration: | Compatible with 1771-WA field wiring arms |
Each isolated channel is designed to effectively cut off electrical crosstalk at the load end, thereby ensuring the stability of the main control system operation
The front panel's dense LED indicator array supports the maintenance personnel to instantly locate the faulty circuit, significantly reducing the troubleshooting time
The Allen Bradley 1771-OBN, with its high-density channel layout, significantly compresses the space occupied by single-point control and optimizes the wiring within the cabinet
This module maintains electrical parameters stable within a wide temperature range of 0 to 60 degrees Celsius. The specially coated circuit board effectively suppresses leakage current in high-humidity environments. The sturdy engineering plastic casing and internal fastening structure have excellent shock resistance, enabling it to continuously perform error-free output in harsh workshops with strong electromagnetic interference and mild corrosive gases.
The module is deeply compatible with the underlying data addressing protocol of PLC-5 and classic programmable controllers, seamlessly connecting to the existing 1771 I/O framework without additional gateways. The Allen Bradley 1771-OBN fully compatible with outdated AC control circuits makes the on-site renovation extremely smooth. Combined with the plug-and-play physical characteristic of the wiring arm, it enables rapid integration and application within the production line downtime window.
