32Channels 18B20 Rs485 Modbus Output Temperature Acquisition Module

Product Description

1: YC1001-19 channel uses 18B20 sensor

2: YC1001-19 channel uses AM2301 or AM2305 sensor

3: YC1001S-32 channel uses 18B20 sensor

4: YC1001S-32 channel uses AM2301 or AM2305 sensor

The standard MODBUS RTU protocol slave device can be accessed as the extension terminal of PLC, MCGS and Kingview.

It is used in temperature measurement fields such as computer room, greenhouse and bean sprout generator.

Connection distance:

After actual measurement, 4 * 0.75 national standard oxygen free copper shielded signal wire is used, with a length of 150 meters and a wire resistance of 2.2 ohms,

The terminal is connected with AM2301 or 18B20 sensor, which can communicate normally.

1 General

Main characteristics

Switch input/output control module based on RS485 interface and Modbus protocol.

Isolate RS485 interface and support Modbus RTU protocol.

Support 18B20 temperature sensor and AM2301 temperature humidity combination sensor.

Temperature calculation is completed inside the module, and the temperature value can be read directly, in Celsius; Read the relative humidity value in% RH.

Measuring range: AM2301 sensor: temperature - 40 ~+80 , resolution 0.1 ; Humidity range: 0.0%~100.0%, accuracy: 3%.

AM2305 sensor: temperature - 40 ~+125 , resolution 0.1 ; Humidity range: 0.0%~100.0%, accuracy: 3%.

18B20: temperature - 40 ~+123 .

Power supply: DC 8-30V static power consumption is less than 0.05W.

The standard 35mm guide rail installation method is adopted.

Boundary dimension: working temperature: - 35 ~+50 .

Application field: HVAC, machine room, greenhouse, bean sprout generator monitoring field.
