General Desc.

• 3- / 5-port 3.75 kVAC galvanic isolation
• Low response time
• 2-wire supply > 17 V in Ex / I.S. area
• 1- or 2-channel version
• Universal supply by AC or DC

Application

• Power supply and Ex / I.S. safety barrier with 2-way HART®communication for 2-wire transmitters installed in the hazardous area.
• Ex / I.S. safety barrier with 2-way HART® communication for supplied current transmitters installed in the hazardous area.
• Signal isolator with low response time on analog current signals from the hazardous area.

Technical characteristics

• PR5106B primarily processes current signals of 4...20 mA.
• PR5106B is based on microprocessor technology for gain and offset. The analog signal is transmitted at a response time of less than 25 ms.
• Inputs, outputs, and supply are floating and galvanically separated.
• The output can be connected either as an active current transmitter or as a 2-wire transmitter.

Mounting / installation

• Mounted vertically or horizontally on a DIN rail. As the devices can be mounted without distance between neighboring units, up to 84 channels can be mounted per meter.
• PR5106B is recommended as Ex / I.S. safety barrier for 5335D and 6335D.
