"Key features 1-channel isolating barrier 24 V DC supply (Power Rail) Current output up to 650 O load HART IP and positioner Line fault monitoring Accuracy 0.1 % Up to SIL 2 (SC 3) in accordance with IEC/EN 61508This isolating barrier is suitable for intrinsically safe applications.
The device controls SMART I/P converters, electrical valves and positioners in potentially explosive atmospheres.
Digital signals can be superimposed on the analog measured value on the field or control side, which are transmitted bidirectionally.
The current is transmitted via a DC/DC converter and repeated at terminals 1 and 2.
Terminals 2 and 3 are used if short-circuit monitoring is not required.
An open circuit or a short circuit in the circuit on the field side causes a high impedance on the control side and allows the alarm statuses to be monitored by the control system.
If the HART communication resistance in the control circuit is too low, the internal resistance can be used.
Test sockets for connecting HART communicators are integrated into the device terminals.
An error is indicated via LEDs and output via a separate collective error message.
