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

PROTECTED

EQUIPMENT

M-RESTER

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.
