SITRANS I100 HART isolating power supply for rail mounting, with intrinsically safe input for supplying transmitters and for connecting mA sources in hazardous areas.
Isolating power supply for supply of 2-wire transmitters and mA sources with intrinsically safe input, approved up to SIL 2
The isolating power supplies are used for the intrinsically safe operation of transmitters or for connecting to intrinsically safe mA sources and the analog output module (AOM) for SIPART PS2.
The transmitters are supplied with auxiliary power from the isolating power supplies.
HART communication signals are transmitted bidirectionally by the isolating power supplies.
Design
The SITRANS I100 HART isolating power supply is comprised of a compact plastic enclosure (IP30) and is equipped with push-in screw terminals.
On the front are a green LED for indicating the power supply status and a red LED for signaling errors.
The SITRANS I100 Advantage
- Active and passive output 0/4 to 20 mA
