The 9461/12-xx-21 series HART analog input module for Zone 1 has four channels for Ex i operation and provides two-conductor and four-channel HART transmitters for Ex i to operate quad-conductor HART transmitters conductor operates with 0/4 to 20 mA signal. HART communication is two-way. All inputs are short-circuit-proof, electrically isolated from the system, and monitored for wire breaks/short circuits. – Four channels for both two-conductor and four-conductor HART transmitters – intrinsically safe Ex ia IIC inputs with line fault monitoring – modules in Zone 1 can be hot-swappable
