WIRELESS
Wireless communication is becoming increasingly
popular in gas detection, and it is sometimes the only
way to ensure safety in existing infrastructure or remote
locations.
The WX4 can be configured to accept wireless inputs
from an OLCT 200 transmitter or communicate wirelessly
to a compatible ModBus master device. Additionally, the
WX4’s wireless option offers the following features:
900MHz or 2.4GHz FHSS
10mW – 1W Adjustable Tx Power
CSA Div 1 and DIV 2 Antennas
256-bit Encryption
Indoor Range up to 3000' (900 meters)
Outdoor Range up to 10 miles (16 km)
