The module features protection class Ex ib IIC and can be mounted in zone 1 in combination with the excom system. The explosion protec- tion category of the outputs is Ex ia IIC resp. Ex iaD. The outputs are galvanically isolated from each other. HART-compatible transducers can be con- nected to the module. The field device can thus be parametrized directly at the terminals on the DIN rail with a licensed modem. Addi- tional impedance in the circuit is not neces- sary. The host system transmits a digitized con- trol value 0...21000 (independent of the parametrized measuring range). This raw val- ue is then transformed by the AO401Ex into a signal between 0...21 mA. ■ Output module for the connection of ana- log actuators ■ Complete galvanic isolation
