XH-104 Data Acquisition Modules

 

1. Product Introduction
1.1. Product design description
The XH-104 data acquisition module is a general data acquisition module developed by our company for various applications. It is widely used in various industries such as building, HVAC, fire protection, water supply, petrochemical, and environmental protection. It is used by most system integrators and automation companies. The research institute adopts a data acquisition module with extremely high character ratio, stability and reliability.
The XH-104 module can be used alone or extended.

 

1.2. Features
8 channels of DC sampling, which can be connected to various transmitters. 4 DC outputs
2 isolated communication ports (485 or 232), support MODBUS RTU or other protocols, easy to expand. SMD installation, no external bus, high reliability and strong anti-interference ability.
Fastened by cassette guide rails or screws, making on-site installation more convenient.
