G.M. International X1-IS-AO-02-S I.S. SIL2 HART® Isolating Driver module. GMI Intrinsically Safe Isolators, Analog Output

The Isolating Driver X1-IS-AO-02 module is a high integrity analog output interface suitable for applications requiring SIL 2 level in safety related systems for high risk industries. It isolates and transfers a 4-20 mA signal from a controller located in Safe Area to a load in Hazardous Area. The circuit allows bi-directional communication signals, for HART® smart positioners. Line and load open/short circuit detection is provided: the fault in the field is directly mirrored to the PLC AO card as open circuit and it is also reported on the common fault line. To ease maintenance operations, field devices can be disconnected through a two-position insertion/extraction mechanism. This product requires a dedicated Termination Board.
