This basic FieldLogger model has a single RS485 interface functioning as a Modbus Slave, with a USB host for downloading logs to a USB memory stick. Data can also be accessed via Mini USB using free NXperience software. The device gathers data from hardwired universal inputs, logging to 512K internal memory or an additional memory card.
Note: Ethernet port is not included with the Slave model.
We are experienced in the configuration and commissioning of the FieldLogger product line and can offer initial training and ongoing technical support.
FieldLogger is a simple to use industrial grade datalogger, covering a wide range of applications such as monitoring of industrial processes, cold chain/logistics, data centres, building management, and renewable energy. No software purchases or ongoing subscriptions required.
It offers fast, no-code setup with free NXperience software, 512K internal memory, 8 universal inputs, 2 relay outputs, 8 digital I/O, logic operations, configurable alarms, and a Mini USB interface for programming, monitoring, and download. Power supply: 24V AC/DC.
Need Ethernet, Modbus Master or a local display? The Slave model does not support these — choose the FieldLogger Ethernet, 2xRS485 Master/Slave (24V) or the Ethernet + HMI (24V) version with the display factory fitted.
FieldLogger and LogBox products are typically available on 7-10 days lead time. If your requirement is urgent, please contact us.

Technical Details
FieldLogger is a versatile, powerful, and cost-effective data logger handling analogue, digital, and other types of variables with high resolution and speed — high performance and high connectivity equipment, yet easy to configure and operate.
It has 8 configurable analogue inputs that can read thermocouples, Pt100, Pt1000, voltage and current signals. It also has 2 relay outputs and 8 digital ports, individually configurable as inputs or outputs.
Up to 128 mathematical channels can be used to perform operations on the measured values. Up to 32 alarm events can be detected, allowing output activations, emails, and SNMP traps.
Its RS485 interface can operate as a Modbus RTU master or slave — on this Slave model, RS485 is the sole communication interface (no Ethernet).
FieldLogger has one USB interface for connecting to a computer (configuration, monitoring, data download) and another USB port for a flash drive for data retrieval. The 512k logging basic memory can be greatly expanded with an SD card.
Configuration: all FieldLogger models are now configured with Novus's free NXperience software, which replaces the legacy FieldLogger Configurator — no separate configurator is required. NXperience connects via USB or RS485 and provides set-up, online monitoring, logged data download, and export to spreadsheets and other formats.
Compare FieldLogger Models
- Slave, RS485 only — 24V AC/DC (this model) | 100-240 VAC: entry model, Modbus RTU Slave, no Ethernet and no HMI support.
- Ethernet, 2xRS485 Master/Slave — 24V | 230V: adds Ethernet, Modbus Master and MQTT; an HMI display can be fitted now or later.
- Ethernet + HMI, factory assembled — 24V | 230V: as above, supplied with the colour HMI display already fitted.
- FieldLogger HMI Accessory — clip-on or remote-mount colour display for the Ethernet models.
Frequently Asked Questions
Does this model include Ethernet?
No — Ethernet is not included on the Slave model; if you need Ethernet connectivity, see our Ethernet-equipped FieldLogger variants.
Do I need ongoing software subscriptions?
No — configuration, monitoring, and data download use the free NXperience software with no software purchases or subscriptions required.
What support is available for setup?
We're experienced in FieldLogger configuration and commissioning and can offer initial training and ongoing technical support.
Do I still need the FieldLogger Configurator software?
No — the FieldLogger Configurator has been replaced. All FieldLogger models are now set up, monitored and downloaded using Novus's free NXperience software, connected via USB or RS485.
