Electronic level relay ENR

Product catalog summary

Specifications:
The document provides technical specifications for an electronic level relay (ENR) used for level control technology. The relay is designed for measuring ranges from 0.1 to 2 meters with a maximum inaccuracy of 2.5% at 25°C and a resolution of 0.01 meters. It operates at a voltage of 230 V-AC with a permissible operating voltage range of ±10%. The device is suitable for ambient temperatures between -20°C and +60°C and can be stored at temperatures from -40°C to 80°C. It is protected against shock according to VBG 4 and has an enclosure protection rating of IP 40.

Procedures:
The ENR relay is mounted on a 35 mm DIN-rail connector and uses cage clamps for terminal connections. It features a quick-connect pressure connection suitable for pneumatic tubes, such as the 6 x 1 mm Festo PAN. The device includes an analogue output with a voltage signal of 0 - 10 V, capable of handling a maximum of 5 mA and is short-circuit proof.

Norms and Standards:
The relay complies with VDE 0110 for clearance and creepage distances and VDE 0660 for series voltage. It also includes an isolating transformer according to VDE 0550.

Functionality:
The ENR relay evaluates pressure applied to its sensor and controls a connected pump. The pump is activated when the upper threshold is exceeded and deactivated when the lower threshold is reached. Both thresholds are adjustable, and an LED indicator shows when the pump is running.

Accessories:
Accessories include a 2.5 mm jack for analogue output connection with a cable length of 5 meters.

Catalog excerpts

Function: The device evaluates the pressure applied to the sensor. Should a pump for emptying a tank be connected to terminals 11 and 12, then the pump is switched on when the upper threshold is exceeded. The pump is switched off when falling below the lower threshold. Both thresholds are adjustable. The LED illuminates when the pump is running, whereby the relay is deactivated. ■ Electronic level relay for all ranges from 0.1 - 2 m ■ For panel board mounting ■ Measurement according to impact pressure method ■ Relay output ■ Output signal: 0 - 10 V Electronic level relay with integrated relative pressure transformer for panel board mounting, quick-connect for pneumatic tube, two adjustable thresholds, relay output and isolating transformer according to VDE 0550.
