Description
The Positek X005 galvanic isolation amplifier has an input power supply range of 12 to 30 volts dc, making it suitable for a wide range of hazardous area applications. It is tri-port isolated providing isolation between the amplifier power supply, the hazardous area and the X005 output signal. The sensor supply and output are transformer coupled providing 2.5kV isolation between the safe and hazardous area circuits eliminating the requirement for a high-integrity earth.
The output of the X005 is factory configured to either 0.5 to 9.5V or 4-20mA and has a bandwidth of 4.7kHz, making it ideal for servo control loops.
The X005 can also be supplied configured for use with potentiometers.
The screw terminal connector plugs are coded to eliminate cross connection.
X005 is ATEX and IECEx approved for use with Positek® Intrinsically Safe Position Sensors. The sensors are ratiometric i.e. the output signal scales with the supply voltage, to ensure the safe area signal accurately corresponds with sensor displacement it is important that the sensor supply is correct.
The Positek galvanic isolation amplifier provides a regulated and resistively limited +5V dc power supply required by the sensors, it can be connected in three or five wire modes. Used in five wire more positive and negative sense inputs enables the unit to dynamically adjust the sensor supply thus ensuring the correct voltage across the sensor. Connected in this way the X005 can compensate for 15Ω conductor resistance. The sense terminals are linked internally so the end user can use the X005 in three wire or five wire mode without the need to fit or remove external links.
