Digital display and button programming: This pressure relay is equipped with a digital display screen that can display the current pressure value in real time. Meanwhile, through button programming, users can easily set preset switch points and delay times to meet different control requirements.

Multiple output modes: EDS348-5-250-000 provides multiple output modes, including switch output and analog output. Users can choose the appropriate output mode according to their actual needs to achieve more flexible control strategies.

Compact and sturdy structure: This pressure relay adopts stainless steel film and DMS built-in pressure sensor, which is compact and sturdy, and can adapt to harsh working environments.

Additional adjustment functions: In order to adapt to specialized application scenarios, EDS348-5-250-000 also has many additional adjustment functions, such as switching delay time, output N/O or N/C functions, etc.

3、 Functional parameters

Model: EDS348-5-250-000

Measurement range: Depending on the specific model, it usually covers a wide pressure range.

Accuracy level: 1%

Output mode: Optional 1-channel switch output (1.2A load capacity, no analog output), 2-channel switch output (1.2A load capacity, no analog output), or 1-channel switch output and 1-channel analog output (4-20mA).

Display mode: 3-digit display, key programming.

Pressure connector: G1/4A external thread (DIN3852), can be directly installed on the hydraulic manifold block.

Electrical connection: Qualified electrical work must be carried out in accordance with relevant national regulations, and the casing must be well grounded.

4、 Matching plug and installation bracket

For the convenience of users, EDS348-5-250-000 pressure relay can be equipped with plugs and mounting brackets.

Plug: Using a 5-core electrical connector to ensure the reliability and stability of electrical connections. Users can choose the appropriate plug model and specifications according to their actual needs.

Installation bracket: Provide a dedicated installation bracket to facilitate users in fixing the pressure relay in the appropriate position. The installation bracket design is reasonable, the structure is sturdy, and it can withstand significant mechanical stress and vibration.

5、 Application scenarios

EDS348-5-250-000 pressure relay is mainly used for pressure monitoring and indication in hydraulic and pneumatic systems, as well as in situations where high-frequency switching or high switching accuracy is required but mechanical pressure relays are not capable. For example, in scenarios such as accumulator pressurization, unloading control, or pump and compressor control, this pressure relay can perform excellently.

VI. Summary

EDS348-5-250-000 pressure relay has become an important control component in hydraulic, pneumatic, and refrigeration fields due to its high-precision measurement, digital display and button programming, multiple output modes, compact and sturdy structure, and additional adjustment functions.
