SIEMENS Isolation Power Supplies and Output Isolators

A power supply units and isolation amplifiers designed to support 2-wire transmitters, provide galvanic isolation for analog unit signals, and control electropneumatic positioners. These components play a crucial role in ensuring the safe and reliable operation of instrumentation in various industrial settings.

The product range includes several device versions:

  1. SITRANS I100 HART isolating power supply: This unit, designed for rail mounting, features an intrinsically safe input for supplying transmitters and connecting mA sources in hazardous areas. Its focus on safety and compatibility with hazardous environments makes it an essential component for ensuring operational integrity.

  2. SITRANS I200 HART output isolator: Also for rail mounting, this isolator incorporates an intrinsically safe output, catering to the control of valve positioners, i/p converters, or indicators in hazardous areas. Its functionality aligns with the need for precise and secure control within challenging operational conditions.

  3. SITRANS I300 isolating power supply: With an intrinsically safe EIA?485 interface, this unit, designed for DIN rail mounting, is tailored for 4-wire devices. Its versatility and compatibility with various devices make it a valuable asset in ensuring reliable power supply and isolation for a range of applications.

These offerings reflect a commitment to providing robust, safety-focused solutions for power supply, isolation, and control requirements in industrial environments. 


SIEMENS SITRANS I100

Isolating power supplies are utilized for the intrinsically safe operation of transmitters or for linking to intrinsically safe mA sources and the analog output module (AOM) for SIPART PS2. These supplies provide auxiliary power to the transmitters. Moreover, they enable bidirectional transmission of HART communication signals.
