HYDAC EDS300/EDS3000 pressure relays are readily available. The HYDAC EDS300 is a compact electronic pressure relay with a digital display. Depending on the model, it may have one or two digital outputs, or one or two digital outputs and one analog signal output.
This HYDAC pressure relay is adaptable to modern control concepts.
Installation: The EDS300 pressure relay comes with a G1/4A external screw (DIN3852) pressure connector. It can be directly mounted to pipelines or hydraulic valves. In critical applications (such as severe vibration and impact), the EDS300 must be mechanically decoupled.
In this case, the pressure connector must be connected via a pressure testing hose.
A clamp (ZBM300) is provided for plate mounting. Using a ZM14 connector ensures the display panel faces the observer. Features of the HYDAC EDS300 series pressure relays: HYDAC pressure switches with a three-digit LCD display; pressure range adjustable via touch buttons: 16 to 600 bar.
Structure: Supports 1 or 2 digital output signals; or 1 or 2 digital output signals plus 1 analog output signal; transistor output load 1.2A. HYDAC pressure switches come in many types with varying constructions, but their working principle is the same.
They consist of a contact system, an arc-extinguishing system, a protection device, and a transmission mechanism.
The contact system connects the power supply and load through the closing of the latches in the transmission mechanism, enabling normal operation of the electrical equipment. The overcurrent coil and load circuit are connected in series, while the undervoltage coil and load circuit are connected in parallel.
During normal operation, the magnetic force of the overcurrent coil is insufficient to attract its armature, while the magnetic force of the undervoltage coil attracts its armature.
When a fault exceeds the rated load or a short circuit increases the current by a certain value, the overcurrent coil immediately attracts its armature, which drives the lever to open the latches, breaking the circuit.
If the voltage drops for some reason, the undervoltage coil's attraction decreases, and the armature is pulled open by the spring, which in turn drives the lever to open the latch, breaking the circuit. In addition, a thermal relay is installed for overload protection.
When the load is overloaded, the bimetallic strip bends, also opening the latch and breaking the contacts, thus providing overload protection. The German HYDAC pressure switch, also known as a contactless proximity switch, is an ideal electronic switching sensor.
When a metal object approaches the switch's sensing area, the switch can issue an electrical command quickly and without contact, pressure, or sparks, accurately reflecting the position and stroke of the moving mechanism.
Even for general stroke control, its positioning accuracy, operating frequency, service life, ease of installation and adjustment, and adaptability to harsh environments are unmatched by ordinary mechanical limit switches. It is widely used in machine tools, metallurgy, chemical, textile, and printing industries.
In automatic control systems, it can be used as a limit switch, counting, positioning control, and automatic protection element. Proximity switches are characterized by long service life, reliable operation, high repeatability, no mechanical wear, no sparks, no noise, and strong vibration resistance.
Therefore, their application range is increasingly wide, and their development and innovation are extremely rapid. HYDAC pressure relays EDS300 and EDS3000 are readily available. HYDAC pressure relay EDS300 applications: The EDS300 is a compact electronic HYDAC pressure relay with a digital display.
Depending on the model, it comes with one or two digital outputs; or one or two digital outputs and one analog signal output. This pressure relay can adapt to modern control concepts. The switching point and corresponding hysteresis can be adjusted via touch buttons.
To better suit specific applications, the device has many additional adjustment functions, such as switching delay time, N/O or N/C output functions, etc.
The EDS300 is mainly used for pressure monitoring and indication in hydraulic and pneumatic systems, and in applications requiring high-frequency switching or high switching accuracy where mechanical pressure relays cannot meet the requirements.
This device is an ideal control element for accumulator pressurization, unloading control, or pump and compressor control.
HYDAC Pressure Relay Features: Features a compact and robust design with a built-in DMS pressure sensor on a stainless steel diaphragm, 1% accuracy, a 3-digit display, key-operated programming, easy operation, independently adjustable switching point and return hysteresis, and various additional functions.
HYDAC Pressure Relay Installation: The EDS300 pressure relay comes with a G1/4A external thread (DIN3852) pressure connector. The pressure relay can be directly mounted to pipelines or hydraulic valve blocks.
In critical applications (such as severe vibration and impact), the EDS300 must be mechanically decoupled; in this case, the pressure connector must be connected via a pressure testing hose. A clamp (ZBM300) is provided for panel mounting. Using a ZBM14 connector ensures the display panel faces the observer.

Plain language sourcing guide for HYDAC pressure relays EDS300 and EDS3000 are readily available.
Start with the full model name. Check the brand name. Check the part number. Check the code on the old unit. These small checks help you avoid a wrong order.
Take one clear photo of the front label. Take one photo of the side label. If the part has a cable, plug, port, seal, coil, or screen, take a photo of that area too.
Tell us the quantity you need. Tell us your country. Tell us the date when the plant needs the part. We can then check stock, lead time, safe packing, and the best shipping plan.
If the exact model is no longer made, do not guess. Send the old model and the use case. LEHIY can compare close options and explain which choice is safer for repair work.
Use simple order notes. Write the model in one line. Write the quantity in one line. Write the delivery country in one line. This helps our team reply faster.
Check the old part before removal. Look at the label. Look at the connector. Look at the mounting size. Look at the voltage or pressure rating if it is shown.
Do not rely on a short nickname for a part. Many industrial items have close versions. A small suffix can change the plug, output, range, or software setting.
Ask for a stock check if the plant is stopped. Ask for a lead time if the order is planned. Ask for packing photos if the part is fragile or heavy.
For a replacement order, tell us what failed. Tell us where the part is used. Tell us if an equal model is acceptable. This makes the first answer more useful.
For repeat orders, send the last invoice, old label, or old packing photo. The same reference can help us match the correct product again.
For urgent service, keep the message simple. One model, one quantity, one photo, and one delivery target are enough for a fast first check.
