Product description:

I. overview

The utility model relates to a switch quantity transmitter, which is a device which can convert the measured AC voltage into a DC voltage or a relay contact according to a specific requirement. Three combination

The transmitter is composed of three independent and isolated single switch transmitter circuit, which has the functions of three single way switch transmitter

Function. The transmitter can be widely used in electric power, post and telecommunications, petroleum, coal, metallurgy, municipal and other departments.

Two, model

Single AC switch transmitter: YWE-K1

Three AC switch transmitter: YWE-K3

Three, the main technical indicators

1) input: AC 0 ~ 600V, 45 ~ 55Hz or ~ 15A, 45 ~ 55Hz.

2) output:

A, voltage input:

When the input voltage is greater than or equal to a critical value (e.g. 100V), the output is high (5V), or the output of the relay contact is closed.

When the input voltage is less than (for example, a certain critical value (100V) of less than 10V) or equal to 90V, the output is low (0V), or the relay

Point output (open).

B, current input:

When the input current is greater than or equal to the critical value (e.g., 250mA), the output is high (5V), or the output of the relay contact is closed.

When the input current is less than or equal to the critical value (e.g., 230mA), the output is low (0V), or the output of the relay contacts (open).

V C, relay contact capacity: DC 30V, 1A

Voltage input and current input critical points can be set according to user requirements (such as: 150V, 200V or 0mA, etc.).

3) auxiliary power supply: DC 5V, 12V, 24V

4) power frequency withstａnd voltage: input / output, input / power supply: AC 2kV/min, leakage current 1mA.

5) insulation strength: ≥ 20MΩ

6) working environment: temperature: -10 to 50 degrees Celsius, humidity: 10 ~ 90% (no condensation)

7) appearance size: YWE-K1:42mm× 75mm× 70mm

YWE-K3:110mm× 75mm× 70mm

Four, wiring

Five, installation

Using DIN rail and screw two installation methods, the width of the guide rail is 35mm. Screw size is M3× 12.

Six, matters needing attention

1, the input and output must be one-to-one correspondence.

2, the use of the environment should be no conductive dust and non corrosive metal and the destruction of insulating gases exist, altitude should be less than 2500 meters.
