2-WIRE PROGRAMMABlE
TRANSMITTER 5131
• 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
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.
Technical characteristics
The unit is based on a microprocessor core with an efficient program operation.
The basic calibration data and present set-up are stored in an EEPROM thereby
avoiding the loss or change of data at power off. The 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.
Input types
Temperature input - jumper in position 1:
Thermocouple input
(TC) for standard thermocouples type B, E, J, K, L, N, R,
S, T, U, W3, W5, LR according to the norms IEC 584, DIN 43710, ASTM E988-90
and GOST 3044-84.
