SMART Current Driver/Repeater
Opis
This signal conditioner is loop powered and isolates a 4 mA .. 20mA signal for transmitters and positioners and is HART compatible. 1-channel signal conditioner, 24 V DC supply (loop powered), Current input/output 4 mA .. 20 mA, HART I/P or transmitter power supply, Low voltage drop, Line fault detection (LFD), Up to SIL 2 acc. to IEC 61508, Transfer direction: to the field / to the control systempa. The low voltage drop of 5 V in comparison to active signal conditioners also allows transmitter applications with unstable power sources between 20 V DC .. 30 V DC. Line fault detection of the field circuit is possible if the control loop in the safe area is monitored for overscale or underscale conditions of the 4 mA .. 20 mA range. The module can also be used for controlling solenoid valves and discrete outputs, such as LEDs. In this case, terminals 8- and 9+ are driven with a 24 V signal.
