4G/LTE Industrial RTU Gateway
Equipment options & specifications
Cellular RTU gateway for pump stations, water telemetry and remote industrial monitoring — collects RS485, analog and digital signals and uploads data over 4G LTE.
Appearance, connectors and included accessories follow the configuration confirmed in your quotation.
Illustration: remote-monitoring integration with field enclosure, gateway, power and industrial equipment.
Bring existing farm equipment into one record
Connect compatible field signals to the selected collector. Start with the sensors and controller already on site, then agree units, timestamps and the destination for each reading.
Connect water and industrial monitoring points
Remote utilities and factory teams can use the same collection approach. The required interfaces, power, network and buffering behavior must match the selected device.
Specifications & version options
Cellular uplink
4G / 3G / 2G; modem and LTE bands selected for the target country
Serial interfaces
1 × RS485 field port plus 1 × RS232 configuration port
Field inputs
4-20mA / 0-5V analog and dry-contact digital input; channel count confirmed by hardware revision
Public documents describe this product family and selection options. Wiring, register maps and compliance documents must match the model and version selected for your order.
Confirm the LTE bands for your target country first so a compatible cellular module can be selected and documented.
List the field signals you need to collect (RS485 / Modbus registers, dry contacts and 4-20mA or 0-5V analog signals). The exact channel count must be checked against the selected hardware revision.
For this RTU family, define an MQTT broker or transparent TCP / UDP endpoint, payload fields, authentication and TLS requirements before quotation. Modbus TCP or a custom API requires a separately verified gateway or firmware scope.
For an outdoor or off-grid pump or tank site, size the DC supply, solar package, antenna and weather-rated enclosure as a separate site package.
Compatible with
RS485 / Modbus sensors and meters
4-20mA or 0-5V transmitters
Dry-contact alarms and status switches
MQTT broker or transparent TCP / UDP endpoint
Typical package
Cellular RTU with a country-matched modem
SIM and antenna accessories
RS485 and/or analog / dry-contact field devices
DC supply and a weather-rated enclosure for outdoor sites
Applications
I/O, protocol, antenna, power, enclosure and upstream platform are selected for the project.
Use this cellular RTU when a remote pump station, water site or industrial asset has mixed RS485, analog and dry-contact signals but no practical wired backhaul. This product family collects the field data and uploads it over a country-matched cellular module using MQTT or transparent TCP / UDP.
Pump run, fault, pressure and level telemetry from remote stations
Tank, well and reservoir monitoring over 4G LTE
RS485 Modbus meter and sensor collection
Dry-contact and analog alarm reporting to an MQTT broker or TCP / UDP endpoint
This product family has one RS485 field port, one RS232 configuration port, 4-20mA or 0-5V analog-input capability, and dry-contact digital-input capability. The exact analog and digital channel count is confirmed against the selected hardware revision before quotation.
How can the RTU upload data?
The functions include Modbus RTU collection, MQTT 3.1 / 3.1.1 with QoS 0 / 1 / 2, retained messages, a custom payload template and a TLS option, plus transparent TCP / UDP. Other protocol-conversion or custom API behavior requires a separately verified scope.
What must be checked for the target country?
The cellular modem and LTE bands are selected for the destination country and operator. The SIM, antenna, field power, outdoor enclosure and destination-market documentation are also confirmed for the ordered configuration.
When should a remote pump station use a 4G LTE industrial RTU instead of LoRaWAN?
Use a cellular RTU when one cabinet already has several analog, digital or RS485 points and no local LoRaWAN gateway is planned. LoRaWAN fits a cluster of low-data points around one gateway. Country bands, SIM or APN rules and the destination SCADA or MQTT endpoint are confirmed before the path is frozen.
Can the RTU keep Modbus meter data if the cellular link drops?
Buffering depends on the selected configuration. Specify the required retention, timestamps and behavior during network and power failures. Confirm these recovery functions in the quotation and test them with the selected firmware.
What should I provide when requesting a quote for the 4G/LTE Industrial RTU Gateway?
Target country, mobile operator and known LTE bands; RS485 register list plus dry-contact and 4-20mA / 0-5V point counts; MQTT broker or TCP / UDP endpoint, payload, authentication and TLS requirements; Available DC power, outdoor enclosure and antenna conditions
Where can I compare available model options?
Open the Application selection guide linked on this page. Use it to compare equipment options before requesting a configuration.
Will it work with my existing system?
Check the field signal, supply, protocol and receiving platform against the selected model. The connection options listed on this page are a starting point; send your equipment model or interface document so we can check the combination before ordering.
