Lightning Surge Protectors for

Electronics Equipment M-RESTER

LIGHTNING SURGE PROTECTOR FOR

STANDARD SIGNAL LINE & PULSE USE

Functions & Features

• Designed specifically for 4 – 20mA DC and

pulse signal line including both 4-wire and 2- wire

transmitters

• Life monitor function helps you to decide when you should

replace the surge protector; reduces maintenance and

prevents downtime

• Pressing CHK (Check) button confirms the degradation

and life span of the surge protection circuits with LEDs

• Absorbs surges only without affecting instrumentation

signal

• No interruption of signal by unplugging surge protector

element
