Libratherm .Signal Isolator DC to DC Signal – ISM-10-1-1

Description

Accepts K type thermocouple or RTD (Pt-100) sensors as the inputs and provides optically isolated and proportional V/I analogue 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.
• 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.

• Parameters	Description
  Input	1) RTD(Pt-100)
