Request to Quote
  • Accepts AC/DC signal inputs and provides optically/galvanically isolated proportional V/I analog output.
  • On site calibration facility-using ZERO/SPAN presets.
  • Operates on 230VAC/110VAC or 24VDC (18-36)VDC.
  • Designed using ultra-low drift components for long term stability.
  • The interface of low-level signals coming from the sensors or transducers from the plant to DCS, SCADA, PLC or PID process controllers without ground line interferences.
  • Signal multiplier – single input and 2 to 4 outputs.
ParametersDescription
Input1) DC input - 50mV/75mV/100mV - DC shunt
2) AC input - Current (through external CT) (0-1) A or (0-5) A or Voltage (0-110) VAC or (0-230) VAC or (0-440) VAC
3) High voltage DC from Bridge rectifier or others – 200,400,600,700VDC
Output(4-20) mA, (0-5) VDC, (0-10) VDC
For current output, RL (max.) = 500 Ohms.
For voltage output, RL (min) = 100K Ohms.
No. Of Outputs 1 to 4 parallel independent outputs can be provided for single input. Each output can be same or different.
AccuracyAbsolute to the input, Output is proportional to the average vale of AC signal.
CalibrationOn site calibration facility through ZERO and SPAN presets accessible to the user.
IsolationInput and Output are galvanically/optically isolated for DC inputs and galvanically isolated for the AC inputs. Power supply is also isolated from Input and Output. (3-way isolation). Multiple Outputs are not isolated from each other.
Isolation VoltageGreater than 1 KV.
Mounting35-mm. DIN rail mounting ABS enclosure.
SupplyAC Supply: 230VAC +/-10%, 50/60Hz or
DC Supply: 24VDC (18-36)VDC .
