Lightning Surge Protectors for
Electronics Equipment M-RESTER
GENERAL SPECIFICATIONS
Construction: terminal board; terminal cover provided
Connection: M3.5 screw terminals (torque 1.1 N·m)
Screw terminal: Nickel-plated steel
Housing material: Steel
LIGHTNING SURGE PROTECTOR FOR
MULTI-CHANNEL USE
LED monitor: Red
(high discharge current capacity)
The leakage current from voltage limiter increases due to its
degradation.
Functions & Features
• Protection for semiconductor switches of discrete outputs
against lightning surge damage
LED becomes brighter gradually in proportion to this
leakage current.
• Applicable to both negative and positive common signals
• Applicable to multi analog signals (non-isolation between
channels)
INSTALLATION
Operating temperature: -5 to +55°C (23 to 131°F)
Operating humidity: 30 to 90 %RH (non-condensing)
Mounting: Surface
• Space saving with multi-channel protectors
• LED monitor indicating degradation of voltage limiter
• LED monitor driven by discrete I/O signal without auxiliary
power supply
Weight: 520 g (1.15 lb)

(e.g. MDR2-8NA)
*MDR2 is operational as an SPD despite less than +20 (for
MDR2-8PA) or more than -20 (for MDR2-8NA). However,
the function of the monitor LED is not guaranteed.

CROSSOVER WIRE
A crossover wire between M-RESTER ground and ground or metallic
housing of equipment is required for protection.
If the protected equipment has no ground terminal, ground the
M-RESTER only.
