The Yokogawa AR-SA is a surge arrester designed to protect DC current signal lines from voltage surges. It is ideal for shielding sensitive electronic equipment in industrial environments.

Key Features and Specifications

• Voltage Range: The AR-SA operates within a specific DC voltage range. This range ensures compatibility with the protected equipment’s voltage levels.
• Clamping Voltage: The arrester limits the maximum voltage passing through to the equipment. During a surge, the arrester conducts excess current to ground, protecting the equipment.
• Response Time: The speed of the arrester’s reaction to a surge is critical. A faster response time offers enhanced protection.
• Discharge Capacity: This measures the arrester’s ability to handle surge energy. Higher discharge capacity means the arrester can manage larger surges.
• Mounting Options: The AR-SA likely supports standard mounting methods, such as DIN rail or panel mounting, simplifying installation.
• Environmental Considerations: Designed for harsh industrial environments, the AR-SA may have ratings for temperature, humidity, and vibration resistance.
