LIGHTNING SURGE PROTECTOR FOR
POTENTIOMETER USE
Functions & Features
INSTALLATION
• Designed specifically for potentiometer or
slidewire circuits
Operating temperature: -5 to +55°C (23 to 131°F)
Operating humidity: 30 to 90 %RH (non-condensing)
Mounting: Surface or DIN rail
• Protects potentiometer transmitters from lightning surge
damage that enters on the wiring between the
potentiometer and the transmitter
• Absorbs surges only without affecting instrumentation
signal
Weight: 140 g (0.31 lb), standard
