1763-NC01 | Allen-Bradley RS-485 DH-485 cable, 8-pin mini DIN to 6-pin terminal block, 30 cm

The 1763-NC01 is a DH-485 communication cable from Allen-Bradley designed specifically for MicroLogix 1100 controllers. It enables reliable RS-485 serial communication between the PLC and external devices like HMIs, other PLCs, or network modules. One end features an 8-pin Mini DIN connector that plugs into Channel 0 of the MicroLogix 1100, and the other end is a 6-pin terminal block. The cable supports DH-485 and Modbus RTU protocols for master/slave communication. It is ideal for industrial daisy-chained serial networks.

The cable has a fixed length of 30 centimeters, which is ideal for short-range panel wiring or internal cabinet connections. This compact length minimizes clutter while providing a clean, efficient link between the MicroLogix controller and its connected devices. Its short size also reduces the risk of signal interference and allows precise routing. The cable diameter is standard for DIN-based cables and fits easily in wire ducts. It's purpose-built for neat, secure control cabinet installations.

The 1763-NC01 is built with basic insulation but does not include a full electromagnetic shield. It’s suitable for use in low-interference environments, such as inside control panels with proper cable segregation. For noisy or high-EMI environments, it’s recommended to run this cable away from power lines and use twisted-pair signal wiring. The terminal end allows for external shielding or grounding methods if required. Always follow Rockwell’s best practices for serial wiring layout.

The 1763-NC01 is specifically designed for MicroLogix 1100, using its Channel 0 Mini DIN port. It is not directly compatible with other PLCs unless they feature a similar DIN interface and protocol support. For broader PLC families, Rockwell offers different cables and adapters tailored to their communication ports. Using the 1763-NC01 with incompatible devices can lead to connection failures or incorrect wiring. Always consult the device manual for port compatibility.

The 1763-NC01 supports both DH-485 and Modbus RTU Master/Slave protocols. DH-485 is used for Allen-Bradley peer-to-peer networks, while Modbus RTU supports communication with a broader range of industrial devices. These protocols enable the PLC to exchange real-time data with HMIs, drives, and other automation components. The cable’s compatibility allows flexible deployment in mixed-protocol environments. Its physical and electrical design ensures robust and interference-resistant communication.
