LIGHTNING SURGE PROTECTOR FOR EC-CABLE USE
Functions & Features
• Designed specifically for M-System’s 32-point
Transmission System EC-CABLE
INSTALLATION
Operating temperature: -5 to +55°C (23 to 131°F)
Operating humidity: 30 to 90 %RH (non-condensing)
Mounting: Surface or DIN rail
• Protects the transmitter model ECT and the receiver ECR
from lightning surges entering through the twisted-pair
cables connecting the both modules
Weight:
• Applicable to transmission systems by current loops
• Absorbs surges only without affecting instrumentation
