Surge Protection Terminal Blocks for
Double Wire RS485 System

Three Pole Side View of DIN Rail Surge Protection Device The ability to protect Double Wire RS485 can be found in
surge protection devices offered by ASI. When standard double-wire (twisted-pair) system/RS485 with plug-in protection is needed, call on ASI for an EZ solution. These surge arrestors protect against surges at the boundaries from lighting protection zone OB-2 and higher.

Designed and built in accordance to IEC 61643-21:2000+A1: 2008 criteria, these devices limit transients with gas discharge tubes and transient absorbing diodes (Transzorb) in aluminum housings. You can be rest assured that accurate measuring is attained when addressing control and regulation systems.

Nominal voltage range includes surge protection devices from 5 V to 48 V with series impedance per line of 2.2 ohms. The nominal current is rated at 0.5 kA.
