DLG I/O ModBus data loggers can easily interface with all ModBus RTU and TCP devices without any programming knowledge.
DLG models have analog and digital I/O and remote data sending capabilities via MQTT, HTTP REST and FTP communication protocols.
DLG I/O ModBus data loggers
versatility, compactness, and simplicity in a single module
The DLG family of I/O ModBus data loggers allows you to easily interface with all ModBus RTU and TCP devices without programming knowledge.
The three models are equipped with analog and digital I/O, making it a compact device for acquiring galvanic signals such as those from 4-20mA, 0-10V probes, PTC/NTC probes, or discrete signals such as digital inputs and outputs..
They send data remotely via MQTT, HTTP REST and FTP communication protocols.
Ideal for data acquisition applications such as:
- Energy monitoring
- Metering
- Water treatment
- Management of renewable energy plants
- Process control
- Management of temperature control systems (Chiller, HVAC, humidification and heating systems).
PROGRAMMING
No special software is needed to program the device. DLG‘s integrated web server allows for variable configuration, with sampling times ranging from 1 second to 1 hour. The web server allows the configuration of network parameters, data formatting modes (CSV or JSON), remote data sending time and parameters for sending in MQTT format.
In addition to being RTU master and TCP client I/O ModBus data loggers, DLG modules can also be ModBus TCP servers, making all read data available to vision systems such as HMI or SCADA software.
