The 9461/12-xx-21 series HART Analog Input Module for Zone 1 has four channels for Ex i operating and supplying two-conductor HART transmitters and four channels for Ex i operating active four-conductor HART transmitters with 0/4 to 20 mA signals. HART communication is bidirectional.
All inputs are short-circuit proof, galvanically separated from the system and monitored to check for wire breakage/short-circuiting.
- Four channels for both two-conductor and four-conductor HART transmitters
- intrinsically safe Ex ia IIC inputs with line fault monitoring
- module in Zone 1 can be hot swapped
