Signal isolator for electrically isolating an analog DC signal and for converting it to a current signal or a voltage signal depending upon the utilized device variant. Functions as a passive isolator without external supply power and draws its minimal energy requirements from the DC signal.

• Measured quantity and measuring range can be programmed with a PC: facilitates planning and project work, short lead-times, minimal inventory
• Integrated cold junction compensation
• Electrically isolated between input, 2.3 kV output and 3.7 kV auxiliary power / compliant with EN 61 010
• Power supply: integrated AC-DC power pack with large tolerance range
• Open-circuit sensor and short-circuit monitoring / defined output performance in the event of disturbance
• With or without programmable auxiliary power connection
• The following parameters can also be programmed: data related to the measured quantity (e.g. 2, 3 or 4-wire connection for resistance thermometer, "internal" or "external" cold junction compensation for thermocouple etc.), response characteristics, signal flow direction (measured quantity / output quantity "rising/rising, normal" or "rising/falling, inverse" and details regarding open-circuit sensor monitoring (output quantity as a predetermined fixed value between -10 and 110%) / greatest possible flexibility for the realization of measuring tasks
• Output calibration, lower and upper value can be trimmed via software
• Digital measured value information available at the programming interface: facilitates initial start-up, measured values can be displayed at the programming PC
• Available with "intrinsically safe" explosion protection per [EEx ia] IIC
• Serial interface
• P12 housing for top-hat rail mounting
