Page 4: Introduction
1 Introduction The Pyxis LS-200 is a general-purpose ultrasonic sensor. It provides continuous level measurement up to 86 inches (7.2 ft. or 2.2 m) with a 4-20 mA output, RS485, and Bluetooth digital outputs. It can be configured via the uPyxis® App on your mobile phones or computers. The sensor is powered by a 24 VDC external power supply. -
Page 5: Installation
4.1 Wiring The LS-200 level sensor is powered by a 24V DC power supply from any standard controller, PLC or DCS. The unit offers both 1x 4-20mA and 1x RS-485 Modbus outputs. If the power ground terminal and the negative 4-20 mA terminal in the controller are internally connected (non-isolated 4-20mA input), it is unnecessary to connect the 4-20 mA negative wire (green) to the 4-20 mA negative terminal in the controller. -
