ANALOG INPUT MODULE HART EX I / I.S. INPUTS, 4 + 4 CHANNELS SERIES 9461/12-XX-21

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
