RS-422/RS-485 Signal Transmission
The AKB161 cable provides a physical transmission path for serial communication signals. Its terminal configuration accommodates connections between the ALM-side M4 terminal and the corresponding M3 terminal.
For installation, maintain the specified terminal assignment and cable routing. Additionally, separate communication wiring from high-voltage power conductors to reduce electromagnetic interference.
The cable length follows 5 m increments, while the -M100 suffix identifies the 100 m configuration.
Frequently Asked Questions (FAQ)
Q: What communication interfaces does the Yokogawa AKB161-M100 support?
A: The AKB161 supports RS-422 and RS-485 serial communication connections.
Q: What terminal configuration does this cable use?
A: It connects the ALM side with an M4 terminal to the other side with an M3 terminal.
Q: Can the AKB161-M100 be shortened or supplied in another length?
A: The cable length is specified in 5 m increments, with a maximum length of 100 m. The -M100 configuration specifies 100 m.
Field Installation Guidelines
- Verify the cable model and terminal configuration before installation.
- Connect the ALM-side M4 terminal to its designated interface.
- Connect the opposite M3 terminal according to the equipment wiring diagram.
- Maintain the specified RS-422/RS-485 signal assignments.
- Route communication cables separately from power wiring where practical.
- Avoid excessive bending, tensile loading, and mechanical compression.
- Follow the equipment manufacturer’s grounding and shielding instructions.
- Inspect terminal connections and cable continuity before energizing the communication system.
