KJ330-Z-type repeater 
 Flameproof and Intrinsically Safe Relay relay relay 
 Features: CAN bus can increase the transmission distance and increase the number of CAN bus nodes. 
 KJ330-Z Flameproof and Intrinsically Safe repeaters are mining underground explosion-proof and intrinsically safe relay is based on new standards for monitoring mine safety and coal-related industry standards and design. 127V/36V AC power from the relay, the output all the way to 12V DC power supply intrinsically safe. There is a set of internal capacity 2Ah rechargeable battery pack, AC power supply to ensure power-down, the battery pack to work automatically, so that repeaters can work without interruption.
