Data loggers
DL5
The DL5 is a multichannel industrial data logger in a 144 × 144 mm panel-mount housing, equipped with a 5-inch touchscreen. It supports up to 30 input/output signals and displays up to 100 channels.
Ethernet (Modbus TCP) and RS-485 (Modbus RTU) communication enable integration with a supervisory system (SCADA). The built-in web server provides access to current measurement results and archived data through a browser.
It measures and records temperature, humidity, pressure, flow, level and other process parameters. Depending on the configuration, it supports 4–20 mA and 0–10 V signals, RTD sensors including Pt100, thermocouples, and HART and Modbus RTU Master communication.
DL5 multichannel data logger in a 144 × 144 mm panel-mount enclosure
The DL5 is an industrial data logger designed to collect, display and archive readings from multiple measurement points. Its 144 × 144 mm panel-mount enclosure allows installation in control cabinets, while its modular design enables the hardware configuration to be tailored to the application.
- Supports up to 30 input/output signals, depending on the configuration.
- Displays up to 100 channels.
- 5″ colour LCD touchscreen.
- 32 GB internal data memory.
- Front-panel USB port with a protective cap providing an IP54 rating when closed.
- Ethernet port supporting Modbus TCP Client/Server and a built-in web server.
- RS-485 communication with Modbus RTU — Slave functionality in the base module; Master functionality available with an appropriate expansion module.
- Software for device configuration and measurement data visualisation and analysis.
DL5 data logger applications
The DL5 brings together data from sensors and transmitters installed at different points throughout a system. It can be used for routine process monitoring, equipment commissioning and process trials. The available measurements depend on the installed modules and connected instruments.
In drying and heat treatment processes, the DL5 can record temperatures at several points within a chamber, helping users compare temperature profiles and assess heating uniformity. In ventilation and air conditioning systems, it can monitor temperature, humidity and signals from differential pressure transmitters, for example when checking system operating conditions.
In water management systems, the logger can collect data on tank levels, pipeline pressure and water flow. On test benches, it allows temperature and pressure trends to be compared and, when equipped with a strain gauge input module, can also record signals from force sensors or load cells. Archived readings help users compare successive tests and document process conditions.
Main functions
- Measurement of process variables, with readings displayed in tables or trend charts.
- Two counters per channel, used, for example, to totalise fluid volume from flow measurements.
- Two alarms or control thresholds per channel.
- Minimum and maximum value tracking.
- Mathematical functions using channel, counter and alarm values.
- A configurable 100-point user-defined characteristic curve.
- Measurement data and event logging.
- Email alarm notifications and periodic reports containing counter values and measurement readings.
- Channel setpoint entry via the touchscreen.
- Communication with a host computer system.
Input and output modules
The DL5 consists of a base module equipped with two USB Type-A ports, an Ethernet port, an RS-485 port and a 24 V DC power connection. Up to five input/output modules can be installed to suit the number of measurement points, signal types and required alarm and control functions.

- IN6I — six 0–20 mA or 4–20 mA analogue inputs without a transmitter power supply.
- IN6T — six inputs for RTD temperature sensors (Pt, Ni, Cu, KTY) or thermocouples (J, L, K, U, E, N, B, R, S). Also supports linear resistance measurement from 0 to 4500 Ω or voltage measurement from −140 to +140 mV.
- IN6V — six voltage inputs supporting −10 to +10 V, 0–10 V, 2–10 V, 0–5 V and 1–5 V ranges.

- IN4SG — four ±30 mV analogue inputs for strain gauge sensors with a sensitivity of 1, 2 or 4 mV/V, or a user-defined sensitivity. The module provides a 5 V DC sensor supply and four digital inputs for taring.
Digital and pulse inputs
- IN6D — six digital inputs for state monitoring, frequency measurement from 0.1 to 1000 Hz and pulse counting from 0 to 100 Hz, with transmitter power supply capability.
- IN3D — three digital inputs for state monitoring, frequency measurement from 0.1 to 12,500 Hz and pulse counting from 0 to 100 Hz, with transmitter power supply capability.
Communication modules
- 2RS485(24V) — two independent, isolated RS-485 ports for reading transmitters and other Modbus RTU devices, with transmitter power supply capability.
- 2RS485 — two independent, isolated RS-485 ports for reading transmitters and other Modbus RTU devices.
- 1HRT — a HART port (4–20 mA) with transmitter power supply capability, operating in Primary Master or Secondary Master mode.
Outputs and battery power
- OUT6RL — six solid-state relays for alarm and control functions, rated at 24 V / 0.5 A.
- OUT3 — three programmable analogue outputs: 0–20 mA, 4–20 mA, 0–5 V, 1–5 V, 0–10 V or 2–10 V.
- PSBATT — a NiMH battery power module providing backup operation during a power outage or temporary battery-powered operation. Operating time ranges from 1 to 20 hours, depending on the configuration.
Data logging and archiving
Measurement readings are stored in 32 GB of internal memory. USB and Ethernet access allow data to be transferred for further analysis, while archived trends can be viewed directly on the logger’s display.
- Configurable logging interval for current readings.
- Automatic switching between logging intervals when an alarm occurs.
- Counter value logging intervals from 1 minute to 24 hours.
- File checksums that allow modifications to recorded data to be detected.
