Configured for high-density signal transmission in YOKOGAWA control networks, the YOKOGAWA AKB335-M010 (AKB335 Signal Cable) provides direct physical data link execution between field interface modules and system controllers.

Hardware Specifications

4-20 mA HART Loop Protocol and Signal Integrity

The AKB335-M010 utilizes a dual-layer foil and braid shield construction to maintain signal fidelity in environments prone to electromagnetic interference. Designed to support 4-20 mA HART loop protocol architectures, the oxygen-free copper conductors ensure minimal resistance over the 10 meter span. This configuration facilitates consistent channel-to-channel signal propagation, ensuring that analog data remains within required accuracy tolerances when interfaced with remote I/O subsystems.

Frequently Asked Questions

Q: Can this cable be shortened in the field for custom installation requirements?

A: Field modification is not recommended as it compromises the impedance characteristics and the integrity of the 50-pin connector termination. Any alteration may induce signal reflections or crosstalk within the high-density connection.

Q: Is this cable compatible with high-frequency communication modules?

A: The AKB335-M010 supports operating frequencies up to 1 GHz. Ensure that the specific module interface impedance matches the 100 Ohm specification of the cable to avoid signal degradation during high-speed data transmission.

Field Installation Guidelines

1. Ensure the control cabinet is de-energized before connecting the 50-pin interface to the module.
2. Route the cable through dedicated non-metallic or grounded metallic trays, maintaining a minimum 300 mm separation from high-voltage AC power lines.
3. Secure the connector locking mechanism completely to prevent intermittent contact due to mechanical vibration.
4. Ensure the cable bend radius does not fall below 10 times the cable diameter to prevent stress on the PVC insulation and internal conductors.
5. Perform a continuity check on the shield drain wire to confirm proper grounding at the designated cabinet reference point before system startup.
