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
