Configured for high-density signal transmission in DCS instrumentation, the YOKOGAWA KS1-15*B (KS1-15*B Signal Cable) provides direct physical signal interconnectivity between field terminal boards and I/O modules. This hardware component manages multi-channel data path integrity across distributed control system platforms.

Suffix Breakdown & Model Matrix

• KS1: Base model identifier for the high-density 40-pin signal cable series.
• -15: Specifies the cable length configuration, where 15 equals 15 meters.
• *B: Designates the style code for the connector housing and shielding configuration.

Hardware Specifications

Process Control Signal Integrity

The KS1-15*B utilizes copper conductors and integrated shielding to maintain signal fidelity in industrial environments prone to electromagnetic interference (EMI). The 40-pin connector architecture allows for bulk signal transition, reducing the wiring complexity typically associated with high-density I/O clusters. The PVC insulation ensures flexibility and protection against common environmental factors within control cabinets and cable trays.

Frequently Asked Questions

Q: Can the 15-meter length affect the voltage drop of analog signal loops?

A: Yes, signal loops at lengths of 15 meters must account for the conductor resistance. Ensure the total loop impedance remains within the transmitter and I/O module specifications to maintain accurate 4-20 mA loop operation.

Q: Is the shield drain wire intended for grounding at both ends?

A: Best practice typically involves grounding the shield at a single reference point—usually the cabinet ground bus—to prevent the formation of ground loops that could inject electrical noise into the signal path.

Field Installation Guidelines

• Inspect all 40 pins of the connector headers for debris or oxidation before mating to ensure a gas-tight electrical connection.
• Route the cable through dedicated signal trays, ensuring a minimum separation distance from high-voltage AC lines and VFD power cabling to mitigate inductive interference.
• Avoid exceeding the cable's minimum bend radius during installation to prevent internal conductor damage or shield deformation.
• Ensure the locking clips on the 40-pin connectors are fully engaged to prevent intermittent signal loss due to mechanical vibration.
• Perform a continuity check on signal lines before commissioning the associated I/O loops to confirm correct pin-to-pin mapping.
