The SB3044 provides two fully-floating dc supplies for energizing two conventional 2-wire 4/20mA transmitters which are located in the field, and repeats the current in two floating circuits to drive two control-station loads.
Dimension 114.5mm×99.0mm×17.5mm Number of channels Two Voltage available for transmitter and lines 15V minimum at 20mA Note: maximum open-circuit voltage is 28V. Output signal range 4 to 20mA or 1 to 5V Note: Clear indication should be given in ordering code when 1 to 5V is needed. Control-station circuit load resistance 0 to 550Ω for each output channel Control-station circuit ripple <40μA peak-to-peak Transfer accuracy at 20°C Better than 16μA Temperature drift <1μA/°C Response time Settles to within 10% of final value within 500μs LED indicator Green: power indication Power supply Voltage: (20~35)VDC Current: (with two 20mA signals) 130mA at 20V 110mA at 24V 80mA at 35V Power: 2.64W typical at 24V with two 20mA signals
Isolation 250V AC/DC between control station and filed circuits
