Operators often need to set process values in real engineering units, not abstract signal percentages. SG9648 generates adjustable 0/4..20 mA or 0/2..10 V DC set point signals and lets any display value be assigned to the corresponding output signal.
Set points can be adjusted with the front buttons or, depending on version, by external control signals. Dynamic adjustment increases speed with button or signal duration, while external adjustment can also run linearly with a programmable adjustment time from 1 to 100 s. Programmable limits help keep the set point inside the intended range.
The isolated analog output changes automatically between current and voltage depending on burden, with 0/4..20 mA at ≤500 Ω and 0/2..10 V at >500 Ω. A DIN 96x48 mm panel case, front IP65 protection and red 14.2 mm LED display support clear operation at the control panel.
The device generates isolated 0/4..20 mA or 0/2..10 V DC output signals. Output type changes automatically according to burden.
The set point can be changed with the front buttons. Dynamic operation increases adjustment speed with the duration of button actuation.
Versions with control inputs allow external increase and decrease commands. Adjustment can be dynamic or linear, with programmable time settings.
The red 14.2 mm LED display shows values over ±9999(0) digit. Indicating range and decimal point are freely programmable.
After power-on, the set point can return to the last stored value or a programmed reset value. External reset is available depending on version.
Up to 2 relay SPDT or transistor alarm outputs can be fitted. Switching performance is programmable as minimum or maximum function.
