Page 4: Basic Description
The output is then set on the basis of the surface height. The outputs of the RIL330 level meter are current 4 -20 mA, voltage 0 - 10 V and industrial line RS-485 with Modbus RTU communication. The output of the RIL331 sensor consists of a PNP transistor with an open collector and a two-state current switch 4 mA / 20 mA. -

Taking into account the potential occurrence of electrostatic discharge on non-conducting parts of the level meter, it is necessary to ground the flange of level meters RIL330–Xi– 20–F and sensors RIL331–Xi–20–F, located in an explosive atmosphere, using a ground terminal! It is also necessary to design and take measures to reduce the effects of static electricity to a safe level in the wiring.
