Ex-ISOLATED DRIVER
PRetrans 5105B
1- or 2-channel version
3- / 5-port 3.75 kVAC galvanic isolation
Driver for Ex area
20 programmable measurement ranges
Universal supply by AC or DC
Application:
• Safety barrier for current signals transmitted to I/P converters and displays
mounted in hazardous area.
• Safety barrier for analogue current / voltage signals transmitted to hazardous
area.
• 1 : 1 or signal conversion of analogue current / voltage signals.
Technical characteristics:
• The 20 factory-calibrated measurement ranges in the 5105B can be selected
by the internal dipswitches without the need for a recalibration. Special
measure ment ranges can be delivered.
• PR5105B is based on microprocessor technology for gain and offset. The
analogue signal is transmitted at a response time of less than 25 ms.
• Inputs, outputs, and supply are floating and galvanically separated.
Mounting / installation:
• Mounted vertically or horizontally on a DIN rail. By way of the 2-channel ver-
sion up to 84 channels can be mounted per metre.

HOW TO DISMANTLE SYSTEM 5000
First, remember to demount the connectors with hazardous voltages.
Picture 1:
By lifting the bottom lock, the module
is detached from the DIN rail.
Picture 2:
Then, by lifting the upper lock and
pulling the front plate simultaneously
the PCB is removed.
Switches and jumpers can now be
adjusted.
