A slimline loop-powered isolator from PR Electronics has been added to WIKA's signal isolator product range. The PRetrans 6185 is dedicated to galvanic isolation of signals between sensors/transmitters and PLCs in eg, water treatment, combined heat and power plants and paper mills. The PRetrans 6185 owes its uniqueness to an installation width of less than 6 mm per channel in the 4-channel version and a high isolation voltage of 2 kV. The high isolation voltage ensures that interference from contactors and relays is eliminated and thus does not affect the PLC. The isolator is optimised for a 4-channel version, which keeps the price per channel low. In this way it complements PR Electronics' product range of signal isolators by combining excellent performance and low cost. The high basic accuracy of 16 µA makes the transmitter suitable for transmission of signals in areas demanding high accuracy - even in applications operating with very low current signals.
PRetrans has integrated protection against overcurrent/overvoltage and is thus very useful in applications demanding high reliability. In addition to this, the transmitter is also protected against polarity error at connection. The device has a signal to noise ratio better than 60 dB resulting in a noise influence of less than 0,1% of the full span.
