Description:
|
The single channel DIN Rail Loop Powered Digital Output Isolator, D1047S is suitable to drive a normally de-energized solenoid valve, or audible alarms, or other
process control devices in Hazardous Areas.
The Safety PLC or DCS driving signal powers the final element through the D1047S.
The unit isolate and transfer the signal to the normally de-energized final element, but at the same time, is capable to monitor continuously the line and final element conditions (short and open circuit output line and load continuous diagnostic monitoring with LED indication and normally close transistor output signalling).
This is achieved by means of an independent diagnostic monitoring control circuit which is separately powered (24 Vdc supply line).
Three basic output circuit are available, with different safety parameters, to interface the majority of solenoids on the market. The selection among the three output characteristics is obtained by connecting the final element to a different terminal block.
D1047S provides 3 port isolation (input/output/supply) between the Safe Areas PLC and the Hazardous Areas devices. The unit can be installed in Zone 2, Division 2 location.
To obtain the SIL 2 qualification for normally de-energized loads (must be energized on process demand), the unit uses two driving circuits in a 1oo2 architecture.
