Fused rS-422/485 Surge protector
485FPP
Single stage surge protectors offer a high degree of protection with
Transient Voltage Suppressors (TVS) for each protected line.
Model 485FPP has 600W Transient Voltage Suppressors to clamp voltages
without adversely affecting normal RS-422/485 data. Fast-acting 125 mA
PCB fuses to protect RS-422 and RS-485 circuits against transient voltages
that are too long or too large for normal suppression.
The 485FPP has 4 wires and terminal blocks for easy installation inline
between the data cables – as close as possible to the serial port. Once a
fuse is blown, the unit should be disposed and replaced.
• Protects RS-422 or RS-485 ports
• 600W serial circuit surge suppression
• 125 mA fast-acting PCB fuses
• Simple in-line installation
• One time use, disposable unit
