Описание
The transmitter power supply feeds 2-wire transmitters. 4-channel, Inputs Ex ia, Mounting in Zone 2, Class I/Div.2 or in the safe area, Power supply for 2-wire transmitters with 4 mA ... 20 mApa. Active signals from separately powered field devices and 4-wire transmitters can be connected. Open and short-circuit line faults are detected. The intrinsically safe inputs are galvanically isolated from the bus and the power supply.
