Electronic Pressure Switch EDS 300 Application: The EDS 300 is a compact, electronic pressure switch with digital display. Four different output models are available: with one switching point, with two switching points and both models can also have an additional analogue output signal 4 .. 20 mA. The switching points and the corresponding hystereses can be adjusted via keys. For optimum adaptation to a particular application, the unit has many additional adjustment parameters, e.g. switching delay times, N/O / N/C function of the outputs. The main applications of the EDS 300 are pressure and critical value indications in hydraulics and pneumatics and anywhere where a high switching frequency or a constant switching accuracy places too high a demand on a mechanical pressure switch. The unit is ideal for the construction of accumulator charging circuits or pump and compressor controls. Special features: Built-in pressure sensor with DMS on stainless steel membrane Compact, robust construction Accuracy class 1% 3-digit digital display Simple operation due to key programming Switching points and switch-back hystereses can be adjusted independently Window function Many useful additional functions Setting options: Circuit diagram: Model with 1 switching output and All the settings available on the EDS 300 Model with 1 switching output 1 analogue output are combined in two easy-to-follow menus. Plug to DIN 43650, 3 pole + earth 4 pole Binder plug, series 714 M18 To prevent unauthorised adjustment of the unit, a program disable can be activated. Setting ranges of the switching points and/or switch-back hystereses:
