SMART Current Driver
Description
1-channel isolated barrier, 24 V DC supply (Power Rail), Current output up to 700 Ω load, HART I/P and valve positioner, Line fault detection (LFD), Accuracy 0.1 %, Terminal blocks with test sockets, Up to SIL 2 acc. to IEC 61508, Transfer direction: to the fieldpa. This isolated barrier is used for intrinsic safety applications. It drives SMART I/P converters, electrical valves, and positioners in hazardous areas. Digital signals are superimposed on the analog values at the field or control side and are transferred bi-directionally. Current transferred across the DC/DC converter is repeated at terminals 1 and 2. An open field circuit presents a high input impedance to the control side to allow lead breakage monitoring by control system. If the loop resistance for the digital communication is too low, an internal resistor of 250 Ω between terminals 8 and 9 is available, which may be used as the HART communication resistor. Sockets for the connection of a HART communicator are integrated into the terminals of the device.
