Potentiometer Converter

Opis

1-channel, 24 V DC supply (Power Rail), Potentiometer input, Current output 0 mA ... 24 mA, Accuracy 0.05 %, Up to SIL 2 acc. to IEC 61508pa. Function. The transformer isolated barrier supplies power to the potentiometers in the hazardous area. The loop voltages are transmitted. The transformer isolated barrier is available with current and voltage outputs (terminals 7 and 8). It can be operated in the 3-, 4- or 5-wire mode with the potentiometer. In the 5-wire mode of operation, the potentiometer voltage is measured at terminals 2 and 5 and automatically readjusted. For a 4-wire connection on the transformer isolated barrier, terminals 4- and 5- are bridged. With the resistance adjustment on the front housing panel, it is possible to adjust the final value. For potentiometer resistances greater than 500 Ω, the potentiometer can be used to compensate for lead resistances up to 5 % of the potentiometer value. During adjustment, the potentiometer is set to 100 % of its value and the output signal is adjusted to 100 % of the required value. This adjustment can be repeated setting the potentiometer to 0 %. Terminals 4 and 5 as well as 1 and 2 must be bridged for a 3-wire connection to the potentiometer.
