K1 AC switch quantity transmitterDetailed product description：

·Product parameters

I. Overview

A switch quantity transmitter is an instrument that can convert the measured AC voltage into a specific output DC voltage or relay contact according to specific requirements. Triple combination opening
The switch quantity transmitter is composed of three independent and isolated single switch quantity transmitter circuits, with three single channel switch quantity transmitters
Function. Switching transmitters can be widely used in departments such as power, postal and telecommunications, petroleum, coal, metallurgy, and municipal engineering.

2、 Model number
Single AC switch quantity transmitter: YWE-K1
Three AC switch quantity transmitter: YWE-K3

3、 Main technical indicators
1) Input: AC 0-600V, 45-55Hz or 0-15A, 45-55Hz.
2) Output:

a、 When voltage is input:
When the input voltage is greater than or equal to a certain critical value (such as 100V), output high level (5V), or relay contact output (closed).
When the input voltage is less than (for example, 10V less than a certain critical value (100V)) or equal to 90V, output a low level (0V), or connect the relay
Point output (on).

b、 When inputting current:
When the input current is greater than or equal to the critical value (e.g. 250mA), the output is high level (5V), or the relay contact output is closed.
When the input current is less than or equal to the critical value (e.g. 230mA), the output is low level (0V), or the relay contact output is open.
V C、 Relay contact capacity: DC 30V, 1A
Explanation: The critical points for voltage input and current input can be set according to user requirements (such as 150V, 200V, or 0mA, 1A, 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: ≥ 20M Ω
6) Working environment: Temperature: -10~50 ℃, humidity: 10~90% (no condensation)
7) Dimensions: YWE-K1:42mm × 75mm × 70mm
YWE-K3： 110mm×75mm×70mm

4、 Wiring

5. Installation
Two installation methods are used: DIN rail and screw. The rail width is 35mm. The screw size is M3 × 12.

6、 Precautions
1. The input and output must have a one-to-one correspondence.
2. The usage environment should be free of conductive dust, corrosive metals, and gases that damage insulation, and the altitude should be less than 2500 meters.
