                What is an LTE Series DIN Rail Transmitter?

                The Laureate LTE Series is a DIN rail transmitter with built-in Ethernet communication. It takes a sensor or process input, conditions it through a plug-in signal conditioner board, and delivers both a standardized isolated analog output and digital data over Ethernet using Modbus TCP/IP. The LTE accepts the same broad range of inputs as the rest of the Laureate transmitter family — DC voltage and current, true-RMS AC voltage and current, thermocouple and RTD temperature, load cell and strain gauge, process loops such as 4–20 mA and 0–10 V, resistance, and frequency, rate, or pulse signals — and pairs each input with a 4–20 mA isolated analog output, dual relays, and isolated transducer excitation. What sets the LTE apart from the LT Series is the communication layer: where the LT transmits over RS-232 or RS-485 serial, the LTE connects directly to an Ethernet network, so a transmitter can be read, configured, and monitored from anywhere on the network or remotely. It shares the same measurement engine, accuracy, and high read rate as Laurel's 1/8 DIN panel meters.

                LTE (Ethernet) vs. LT (Serial)

                • LTE Series: Communicates over Ethernet using Modbus TCP/IP — the right choice when the transmitter needs to sit on a plant network or be monitored remotely.
                • LT Series: Communicates over RS-232 or RS-485 serial — suited to point-to-point or multi-drop serial runs.
                • Same core: Both share the Laureate measurement engine, plug-in signal conditioners, 4–20 mA analog output, dual relays, and accuracy. The difference is the data interface.

                How to Choose an LTE Transmitter

                • Input signal: Match the signal conditioner to your sensor — DC, true-RMS AC, thermocouple, RTD, load cell, process loop, resistance, or frequency/pulse.
                • Network: Confirm Ethernet with Modbus TCP/IP fits your control system; choose LT instead if you need RS-232/RS-485 serial.
                • Output and relays: Verify the 4–20 mA or 0–10 V isolated analog output and dual relays meet your alarm or control needs.
                • Isolation and excitation: Check isolation between input, output, power, and Ethernet, plus built-in transducer excitation if your sensor requires it.
                • Mounting and power: Confirm DIN rail fit and a suitable supply voltage for your cabinet.

                Where LTE Transmitters Are Used

                • Networked process control: Reporting conditioned sensor data to PLCs, SCADA, and DCS over Ethernet/Modbus TCP.
                • Remote and distributed sites: Monitoring and reconfiguring transmitters across a facility or from off-site over the network.
                • Energy and power monitoring: Sending voltage, current, and power-factor data into networked energy management systems.
                • Industry 4.0 / IIoT: Integrating field measurements into data historians and analytics platforms over standard Ethernet.

                Frequently Asked Questions

                What is the difference between the LTE and LT transmitter series?

                The two series share the same Laureate measurement engine, plug-in signal conditioners, 4–20 mA analog output, dual relays, and accuracy. The difference is the communication interface: the LTE Series connects over Ethernet using Modbus TCP/IP, while the LT Series communicates over RS-232 or RS-485 serial. Choose the LTE when the transmitter needs to live on a network or be accessed remotely, and the LT when you are running serial.

                What communication protocol does the LTE Series use?

                The LTE Series uses Ethernet with Modbus TCP/IP. That lets a transmitter connect directly to a plant network, report digitally to PLCs and SCADA systems, and be configured or monitored remotely, all at the same time it drives its isolated analog output.

                What inputs can an LTE Series transmitter accept?

                Through interchangeable plug-in signal conditioner boards, the LTE Series accepts DC voltage and current, true-RMS AC voltage and current, thermocouple and RTD temperature, load cell and strain gauge, process signals such as 4–20 mA and 0–10 V, resistance, and frequency, rate, or pulse inputs. You match the board to the sensor, so one Ethernet transmitter family covers a broad range of measurements.

                Does the LTE transmitter still provide a 4-20 mA output?

                Yes. Ethernet communication is in addition to, not instead of, the analog output. Each LTE transmitter provides an isolated 4–20 mA analog output (with 0–10 V available where preferred), so it can feed legacy analog control loops and report to a networked system simultaneously.

                Why mount an Ethernet transmitter on a DIN rail?

                DIN rail is the standardized mounting system used inside industrial control cabinets. Rail mounting lets transmitters clip in next to PLCs, switches, breakers, and relays, keeps wiring tidy with detachable screw-clamp connectors, and makes installation and replacement fast — which suits networked devices that sit in the cabinet rather than on the panel face.

                How accurate are LTE Series transmitters?

                Because they share the measurement engine of the Laureate panel meters, LTE Series analog-input transmitters provide accuracy of 0.01% of reading ± 2 counts with high read rates of up to 60 or 50 conversions per second. Frequency and timer versions use a time-base crystal calibrated to ± 2 ppm. Inputs, outputs, power, and the Ethernet interface are isolated from one another.
