KS1-05*A Yokogawa CENTUM VP Signal Interface Cable

Product Overview

The Yokogawa KS1-05*A acts as a specialized communication artery for CENTUM VP and legacy Yokogawa Distributed Control Systems (DCS). This high-performance signal cable facilitates the seamless transfer of both analog and digital data between I/O modules, terminal boards, and field junction boxes. Engineered to maintain signal purity in electrically noisy environments, the KS1-05*A prevents data corruption and attenuation, ensuring that critical process variables reach the control logic without distortion.

Engineering Advantages

• Superior Noise Immunity: The high-density braided shielding aggressively blocks Electromagnetic Interference (EMI) and Radio Frequency Interference (RFI). This protection proves essential when routing signal cables near high-voltage motor cables or variable frequency drives (VFDs).

• High Flex Life for Tight Enclosures: Yokogawa utilizes a flexible PVC jacket that allows for tight bend radii. This feature simplifies cable management within cramped control cabinets and prevents conductor fatigue during installation or maintenance.

• Flame-Retardant Safety: The insulation material meets strict industrial fire safety standards. In the event of an external fire, the flame-retardant PVC limits the spread of fire along the cable run, protecting critical control infrastructure.

• Low Attenuation Conductors: Precision-twisted pairs minimize signal loss over the 5-meter span. This ensures that low-voltage analog signals maintain their accuracy, which is vital for high-precision flow and pressure measurements in chemical and power plants.

FAQs

Q1: Can the KS1-05*A cable handle high-voltage power transmission?

A1: No. The KS1-05*A is strictly a signal cable designed for low-voltage analog and digital data. Using this cable for AC power distribution will damage the insulation and compromise system safety.

Q2: Is the cable suitable for direct burial or outdoor use?

A2: The KS1-05*A is designed for indoor control cabinet environments or protected cable trays. For outdoor or direct burial applications, you must install the cable within a sealed conduit to protect the PVC jacket from UV radiation and moisture ingress.

Q3: How do the factory-terminated connectors improve reliability?

A3: Factory-molded connectors eliminate the common human errors associated with field-stripping and crimping. These terminations provide a gas-tight seal that prevents oxidation at the contact points, ensuring a low-resistance connection for the life of the system.

Q4: Does this cable support hot-swapping of I/O modules?

A4: While the cable itself is a passive component, it fully supports the hot-swap capabilities of the CENTUM VP hardware. You can disconnect and reconnect the KS1-05*A while the system is live, provided the specific I/O module and DCS configuration allow for it.
