PRetrans 5131 2-WIRE PROGRAMMABLE TRANSMITTER

PRetrans 5131 2-WIRE PROGRAMMABLE TRANSMITTER

The unit based upon on a microprocessor core with an efficient program operation. The PRetrans 5131 2-channel version has a full galvanic isolation between the channels. By way of a jumper on the PCB the input in the standard version can be programmed either for a temperature or a current /voltage input. This means that one channel can work as for instance a temperature transmitter and the other can work as an isolation amplifier. Measurement range, signal parameters, and output span are configured to the present task by way of a PC and PR electronics A/S’ communications interface Loop Link.

Application:

• Electronic temperature measurement with resistance sensor or thermocouple sensor
• Ex barrier for temperature sensors, potentiometers and current/voltage signals
• Conversion of current signals from supplied transmitters to 2-wire 4…20 mA signals
• Amplification of mV signals
• Conversion of linear resistance variation
• Galvanic isolation of analogue signals
• Measurement of floating signals
• Linearisation of non-linear Ohm, mV, mA, or voltage signals
• Separation of circuits in PELV/SELV installations
• The voltage input is programmable in the range 0…250 VDC.

Specification:

• Input for RTD, TC, mV, linear resistance mA, and V
• 3.75 kVAC galvanic isolation
• 4…20 mA loop output
• 1- and 2-channel versions
• ATEX Ex version
• DIN rail mounting
