Choosing a data logger is not only about the number of inputs or communication options. For remote monitoring, the real value lies in how easily the logger can be deployed, how little power it consumes, how many different sensors and systems it can work with, and how much freedom it gives you over your own data.
YDOC data loggers are designed around exactly those principles.
Tiny but tough
Easy deployment in harsh outdoor environments
Remote monitoring equipment is often installed in locations where accessibility is limited and environmental conditions can be demanding.
The RS-525SE combines a compact design with a rugged UV-stabilized polycarbonate enclosure rated IP68/IP69. It is designed for operation from -30°C to +75°C and includes internal monitoring of temperature, humidity, battery condition and cellular signal strength.
Despite its compact size, the logger integrates cellular communication, data storage, multiple sensor interfaces, local processing and flexible power options in one device.
This keeps installations simple and reduces the need for additional hardware in the field.
Low power yet powerful
Featuring modern technologies like LTE-M, MQTT & optional LoRaWAN
Low power consumption is essential in battery- and solar-powered monitoring applications.
The RS-525SE has a sleep current of less than 30 µA at 3.6 V and is available in battery, DC and solar-powered configurations. External sensors can be powered directly by the logger through a programmable 3–21 V excitation output and switched off while the logger is sleeping.
At the same time, low power does not mean limited functionality.
The logger includes integrated LTE-M and NB-IoT communication, together with support for modern protocols such as MQTT and HTTP. It also offers both an integrated eSIM and a physical nano-SIM slot, giving users flexibility in how cellular connectivity is arranged.
Optional internal expansion boards can add functionality such as LoRaWAN where wireless sensor connectivity is required.
Cost effective yet feature rich
Suitable for budget-constrained as well as demanding applications
A cost-effective data logger should not force users to give up useful functionality.
The RS-525SE combines a wide range of interfaces in the standard unit, including current, voltage, potentiometer and digital inputs, together with RS-232, RS-485 and SDI-12. It supports SDI-12, Modbus RTU/ASCII, NMEA-0183 and generic ASCII sensors.
It also provides local processing capabilities through up to 20 calculation channels and 10 aggregation channels. This allows raw sensor data to be converted into meaningful engineering values before transmission.
The result is a platform that can be used for relatively simple monitoring tasks as well as more demanding applications involving multiple sensors, calculations, alarms and telemetry.
Capturing but not constraining
The data is yours, take it where you like
One of the strongest advantages of the RS-525SE is its open architecture.
The logger supports sensors from different manufacturers through standard interfaces and protocols, so users are not tied to a proprietary sensor ecosystem.
The same applies to the data platform.
Logged data can be sent directly to up to six independently selected servers using MQTT, HTTP, FTP or proprietary TCP. Native payload formats include TXT, CSV, JSON and Sparkplug B.
This means users can integrate the logger into their own SCADA system, IoT platform, server infrastructure or customer portal without being forced to route data through a manufacturer-specific cloud.
The principle is simple:
Your sensors. Your data. Your platform.
Secure communication and remote configuration
For remote monitoring systems, secure communication is just as important as connectivity itself.
The RS-525SE supports TLS, including TLS 1.2 and TLS 1.3, as well as secure communication variants such as HTTPS, FTPS and MQTT(S). Remote configuration can be performed through a secure TCP tunnel over the cellular connection.
This allows users to adjust configuration remotely while protecting data and configuration traffic during transmission.
Local configuration through USB-C remains available when physical access is preferred.
Designed for unattended operation
Once a monitoring system has been installed in a remote location, every unnecessary site visit adds cost.
The RS-525SE therefore combines remote configuration with local data storage. It includes 112 MB of internal ring-buffer storage, which can be expanded using a microSD card.
Alarm events can trigger immediate data transmission when an alarm is raised and again when it is cleared, helping users respond quickly to changing conditions.
Why YDOC?
The strength of a YDOC data logger is not one individual specification, but the combination of flexibility, low power consumption, connectivity, openness and remote manageability.
