Ex-isolated driver
5105B
– 1- or 2-channel version
– 3- / 5-port 3.75 kVAC galvanic isolation
– Driver for Ex / I.S. 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 analog current / voltage signals transmitted
to hazardous area.
• 1 : 1 or signal conversion of analog current / voltage signals.
Connections
Technical characteristics
• The 20 factory-calibrated measurement ranges in the 5105B
can be selected by the internal DIP-switches without the need
for a recalibration. Special measurement ranges can be
delivered.
• PR5105B 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.
Mounting / installation
• Mounted vertically or horizontally on a DIN rail. By way of the
2-channel version up to 84 channels per meter can be
mounted.
