YOKOGAWA AR-SA Arrester for DC Current Signal

Description

YOKOGAWA AR-SA Arrester for DC Current Signal is a protective device designed for DC current signal systems, with reference technical specifications and features derived from comparable industrial signal devices. Similar DC signal handling devices offer key performance metrics including insulation resistance greater than 100 MΩ, support for 0-20mA/4-20mA input signals, and response times as low as 200 microseconds. This arrester is engineered to deliver robust signal protection, with expected features such as surge and electrostatic discharge protection, including up to 15kV electrostatic protection and 1500W per-line surge protection, plus self-recovering overcurrent protection to prevent common ground interference. It is designed for industrial environments, operating within a temperature range of -10 degrees Celsius to 45 degrees Celsius, with a humidity tolerance of less than 90% non-condensing, and a wide DC operating voltage range of 12-36V. Installation is intended for standard 35mm DIN rails, with a compact form factor suitable for dense control panels. The device will likely provide electrical isolation with a rated isolation voltage of up to 1500VDC per minute, and may include LED status indicators to confirm power and signal status. It is ideal for integration with DCS, PLC, and other industrial control systems, supporting applications in oil and gas, petrochemical, manufacturing, power, and metallurgy automation projects.
