STANDARD SIGNAL LINE & PULSE USE
Functions & Features
RELATED PRODUCTS
• Base (model: SK-2E)
• 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
GENERAL SPECIFICATIONS
Construction: Plug-in
Connection: M4 screw terminals (torque 0.8 N·m)
Screw terminal: Nickel-plated steel
• Pressing CHK (Check) button confirms the degradation
and life span of the surge protection circuits with LEDs
• Absorbs surges only without affecting instrumentation
signal
Housing material: Flame-resistant resin (black)
Indicators: Activated by CHK (Check) button, see the status
table shown below.
• No interruption of signal by unplugging surge protector
element
BAT: Green LED
ALM: Red LED
Degradation judged: When the leakage current at the
voltage limiter exceed approx. 7.5 μA.
Life time judged: When the number of discharges of the
discharge element reaches the expected life span.
CHK button: Push button; momentary
Battery: Lithium; No recharge or replacement available.
Battery life: 10 years (when used ≤ 2 minutes/month)

GROUNDING
(100 ohms or less)
CROSSOVER WIRE
A crossover wire between M-RESTER ground and the ground or
metallic housing of the equipment is required for protection.
If the protected equipment has no ground terminal, ground the
M-RESTER only.
When the M-RESTER is mounted with DIN Rail Mounting Adapter,
connect the grounding wire to the mounting screw of the M-RESTER.
