The 9460 series analog input module for Zone 1 has eight channels for Ex i operation and provides two-conductor transmitters or up to four active three/four-conductor transmitters with 0/4 to 20 mA. All inputs are short-circuit-proof, electrically isolated from the system, and individually monitored to check for wire breaks/short circuits. – Eight channels for two-conductor transmitters or four channels for three/four-conductor transmitters – intrinsically safe Ex ia IIC input with line fault monitoring – modules in Zone 1 can be exchanged hot
