Most IoT hardware forces a choice:
their platform, or nothing.

You end up with proprietary gateways locked to closed clouds, protocols that don't talk to your existing infrastructure, and recurring fees for data you already own. Apex was built to end that trade-off.

🔒

Vendor lock-in

Proprietary hardware tied to a single cloud platform. When the subscription ends, the hardware stops working.

🔌

Protocol fragmentation

Your site runs Modbus. Your vehicles run J1939. Your solar runs Victron. Nothing talks to anything without custom middleware.

☁️

Mandatory cloud

Air-gapped sites, offline-first operations, and data sovereignty requirements don't fit the SaaS-only model.

📦

Product sprawl

One device for sensors. Another for engines. Another for solar. Three vendors, three portals, three sets of firmware to manage.

One form factor.
Any application.

The Apex DIN Rail family is a range of rugged, 35mm rail-mount controllers and I/O modules designed for panel builders, systems integrators, and OEM machine builders. Every model ships with a built-in web interface, configurable I/O, and native support for the protocols your application already uses.

Deploy a single unit to monitor a cold room. Stack modules across a switchboard to automate a processing plant. Mount one in a vehicle cab-pack to report engine telemetry. Same hardware family. Same configuration tools.

APX-100 Series

Core Controller

The workhorse of the Apex family. Universal I/O with analogue inputs, relay outputs, and multi-protocol serial — in a single DIN module.

4–20mA RS-485 Modbus RTU Modbus TCP 4× Relay Digital I/O Ethernet LTE-M
APX-200 Series

Vehicle & Engine Gateway

Purpose-built for mobile and off-highway applications. Reads engine parameters directly from the vehicle network and reports over cellular with configurable thresholds and alerts.

J1939 / CAN H7S 9–36V DC RS-232 / 485 GNSS LTE Cat-M Ignition sense
APX-300 Series

Energy & Solar Monitor

Native integration with Victron Energy systems and other solar charge controllers. Monitor generation, state of charge, load, and fault states without custom adapters.

Victron VE.Direct VE.Can RS-485 / Modbus 4–20mA Battery monitor AC metering
APX-400 Series

Expanded I/O Module

Add analogue or digital I/O capacity to any APX-100 backbone. Ideal for high-channel-count applications — cold stores, process plant, multi-zone monitoring.

Speaks your
language.

Apex hardware is designed around open standards — not proprietary ones. If your equipment already uses an established industrial protocol, there's a high probability Apex connects to it directly, out of the box.

Modbus RTU / TCP

The most widely deployed industrial protocol. Apex acts as master or slave across RS-485 and Ethernet simultaneously.

J1939 / CAN Bus

Read engine RPM, coolant temp, fuel level, fault codes, and hundreds of PGNs directly from any J1939-compliant engine or vehicle.

RS-485 / RS-232 / TTL

Selectable serial mode. Supports multi-drop bus topologies across legacy instruments, meters, and field devices.

4–20mA Analogue

True two-wire loop inputs with 12/24-bit resolution. Configurable for any sensor: pressure, temperature, level, flow.

H7S

Supported for specialist vehicle and equipment integration applications requiring H7S communication protocol.

Victron VE.Direct / VE.Can

Native support for Victron solar charge controllers, BMV battery monitors, MultiPlus inverters, and MPPT units.

Your data.
Your rules.
Full stop.

Apex devices do not require a cloud subscription to function. Every unit ships with a built-in web interface accessible on your local network from any browser. Configuration, status, and live data — all available without a single packet leaving your site.

When you're ready to push data upstream, Apex publishes over MQTT, REST, or direct to any major IoT platform. You choose the destination. You hold the credentials. We don't see your data.

  • MQTT — Publish to any broker: AWS IoT Core, Azure IoT Hub, Mosquitto, HiveMQ, or your own
  • REST API — Pull data on your schedule via JSON endpoints
  • Modbus TCP slave — Drop straight into SCADA and HMI systems
  • Inductive Automation Ignition — Native tag binding via Ignition drivers
  • ThingsBoard / Losant / Node-RED — Tested and documented integrations
  • Local data logging — On-board storage with CSV export and no expiry
Apex Cloud Optional

When you want more,
it's already there.

For teams that want managed configuration, fleet-wide firmware updates, remote diagnostics, and multi-site dashboards, Apex Cloud is available as a subscription add-on. Same devices. Zero commitment required at purchase.

  • Remote device configuration and firmware OTA
  • Multi-site dashboard and alerting
  • Automated threshold alerts via SMS, email, or webhook
  • Historical data retention and export
  • Role-based access for teams and integrators
  • Audit log for compliance and traceability applications

Fully configured
on site.

Open a browser on any device connected to the same network. Navigate to the device IP. You're in — no app, no drivers, no internet required.

The local web interface provides live sensor readings, I/O status, protocol configuration, network settings, and event logs. Ideal for commissioning in the field, fault-finding without a laptop, or operating in environments where cloud access is not available.

Technician-friendly. Every parameter is labelled. Hover tooltips explain every setting. No specialist software. No dongle. No callout fee.

❄️

Cold Chain & Refrigeration

Monitor compressors, evaporators, door sensors, and ambient conditions across cold stores and refrigerated transport. Alarm on excursions before product is compromised.

🚛

Vehicle & Fleet Telematics

Connect to any J1939 engine — trucks, generators, excavators, marine. Report hours, fault codes, fuel consumption, and temperature to any fleet platform.

☀️

Off-Grid & Solar Energy

Native Victron integration means no adapters, no hacks. Monitor MPPT, battery state, load, and grid-tie status. Perfect for remote sites and hybrid systems.

🏭

Industrial Automation

Retrofit monitoring onto legacy plant without replacing PLCs. Sit alongside existing Modbus infrastructure and feed data to modern SCADA or cloud analytics.

🌾

Agriculture & Remote Sites

Cellular-connected monitoring for pumps, tanks, irrigation, and grain storage. Works where Wi-Fi doesn't. Local logging keeps data safe through connectivity gaps.

💊

Pharmaceutical & Compliance

Audit-ready temperature and humidity records for GDP-compliant storage. Continuous logging, tamper-evident records, and alert escalation on excursion.

Plays well with
your stack.

Apex is designed for integrators and engineers who already have a platform, a workflow, and a preference. We don't compete with your stack — we connect to it.
