4/1 4 Automation 03.07.2008 Remote I/O 05693E00 Analog Output Module HART for Installation in Zone 1 Type 9466/12 �œ 8 channels for control of HART control valves �œ Intrinsically safe Ex ia IIC �œ Galvanic isolation between outputs and system �œ Open-circuit and short-circuit monitoring for each field circuit �œ Connection of the field cables with plug-in terminals �œ Modules can be replaced while powered up (hot swap) �œ Installation in – Zone 1 / Division 1 – Zone 2 / Division 2 – Zone 21 and Zone 22 Zones 0 1 2 20 21 22 Ex i interfaces X X X X X X Installation in X X X X The output circuit generates a current signal of 0 mA ... 20 mA or 4 mA ... 20 mA for the corresponding channel. All outputs are shortcircuit proof. Each output is monitored separately regarding open-circuit and short-circuit. The integrated HART multiplexer permits bidirectional HART communication. The HART information is transferred from the CPU & Power Module via the ServiceBus, or via the fieldbus Profibus DP V1. The interface of the Analog Output Module with the internal data bus of the BusRail is designed with redundancy. Analog control valves (non-HART) can also be operated. 05688E00 4 ... 20 mA HART . . .
