1761-CBL-AM00 | Allen-Bradley | Network Cable

Configured for serial communication data exchange in MicroLogix 1000 controller networks, the Allen-Bradley 1761-CBL-AM00 (1761-CBL-AM00 Network Cable) provides direct physical signal transmission via an 8-pin male-to-male interface.

Hardware Specifications

PLC Deterministic Network Interfacing

The 1761-CBL-AM00 supports serial communication protocol implementation within the MicroLogix 1000 architecture. The right-angle connector profile is engineered for restricted-clearance mounting environments, ensuring mechanical stability in panel enclosures where standard vertical connectors may experience excessive cable strain. The 8-pin DIN configuration maintains signal impedance for RS-232/DF1 or DH-485 physical layer signaling. Deterministic communication velocity is maintained through the factory-molded construction, which mitigates signal attenuation common in unshielded serial interconnects.

Frequently Asked Questions

Q: Does the 1761-CBL-AM00 cable support hot-plugging for MicroLogix serial ports?

A: Serial ports on MicroLogix 1000 controllers are generally robust; however, it is standard engineering practice to cycle the controller to a stopped state or power down the segment before connecting or disconnecting serial cables to avoid voltage transients on the communication bus.

Q: Is this cable compatible with other MicroLogix series controllers using 8-pin ports?

A: The 1761-CBL-AM00 utilizes a standard 8-pin mini-DIN pinout compatible with many MicroLogix 1000, 1200, and 1500 communication ports. Verify the specific pinout mapping in the controller user manual to ensure parity with the communication protocol required (DF1 vs. DH-485).

Field Installation Guidelines

1. Connector Orientation: Ensure the 8-pin connector is keyed correctly before insertion into the MicroLogix port. Do not force the connector if resistance is encountered, as bent pins can cause permanent port damage.
2. Cable Routing: Maintain a minimum clearance of 100 mm from high-voltage AC lines and VFD output cables to minimize electromagnetic interference (EMI) on serial data signals.
3. Strain Relief: Secure the cable to the cable duct using tie-wraps to prevent the right-angle connector from exerting excessive torque on the controller communications port.
4. Environment: Ensure that the ambient temperature at the installation point does not exceed 60 deg C to maintain the integrity of the cable insulation and connector molding.
