The 9461/12-xx-21 HART analogue input module for Zone 1 has four channels for Ex i operation and supplying 2-conductor HART transmitters and four channels for Ex i operation of active 4-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 each for 2-conductor and 4-conductor HART transmitters
- Ex ia IIC intrinsically safe inputs with line fault monitoring
- Module in Zone 1 can be replaced without having to disconnect the power supply (i.e. hot-swapped)
