Industrial control, modular by design.

One controller. A growing family of plug-in I/O and sensing modules on a fail-safe Modbus backplane. Cloud-native monitoring, control and fleet firmware updates — built in from day one.

Fail-safe by contract

Every expansion module enters a defined safe state within 3 seconds of losing the bus. Outputs recover only under explicit host command — never by accident.

Standards, not lock-in

The backplane speaks plain Modbus RTU. Third-party tools can talk to every module directly — nothing proprietary between you and your I/O.

Expansion Modules

Snap-in blades or external DIN modules — same PCB, same protocol, addressable 1–16 on a single daisy-chained cable.

EX-16DO 16-channel isolated output module, standalone EX-16DO

16-Channel Isolated Digital Output

Solid-state PhotoMOS outputs with per-channel surge protection. Bus-loss safe state, wear-free switching.

  • 16× isolated outputs, 200 mA per channel
  • TVS surge protection on every channel
  • Safe-state all-off on bus loss
EX-16DI 16-channel isolated input module, standalone EX-16DI

16-Channel Isolated Digital Input

Constant-current isolated input front end — stable thresholds across the whole supply range, per-channel indication.

  • 16× isolated inputs, constant-current front end
  • Wide-range field voltage tolerance
  • Same blade form factor and backplane protocol
PH-EC dual-channel water quality module, standalone PH-EC

Dual-Channel Water Quality

2× pH + 2× conductivity + 4× temperature on one module — populate one or both channels. Built for hydroponics and fertigation.

  • pH: guarded GΩ input, 24-bit acquisition
  • EC: synchronous-detection, 0–10 mS/cm (K=1.0 cells)
  • Isolated analog front end · probe-fault detection

Bus Access Board

Passive power, earth and RS-485 entry for a module row — inject 24 V mid-row on a long backplane, or run a module group stand-alone under any Modbus master.

  • 9–36 V DC supply, two paralleled terminals per rail
  • Filtered, surge-protected power and bus entries, PE terminal
  • 120 Ω terminator engaged by a wire link · no MCU, no address
EX-6RTD · coming soon

Precision Temperature

2/3/4-wire Kelvin RTD sensing for lab-grade temperature measurement, on the same backplane.

  • Kelvin connection, per-channel reference
  • PT100 / PT1000 support

Built for Fertigation & Water Control

The platform grew up in irrigation: pH and EC sensing, dosing-pump sequencing, flow counting and valve control are first-class citizens — not an afterthought bolted onto a generic PLC.

Sense

pH, conductivity and temperature on the PH-EC module; pulse flow meters and quadrature sensors on the controller's high-speed inputs.

Dose & actuate

Dosing pumps, valves and mixers on EX-16DO solid-state outputs — with a defined safe state when anything upstream fails, so a fault never keeps a pump running.

Supervise

Recipes and interlocks run on the controller in C — your firmware, your rules. The cloud watches, logs and alerts; the site keeps running with or without it.

The same building blocks carry other serious jobs — access control with RS-485 readers and door hardware on isolated I/O is a natural fit.

Honest Engineering

Industrial hardware earns trust in the details. A few of ours, up close.

Dual-core MCU and SDRAM close-up

Dual-core Arm® MCU with external SDRAM and QSPI flash — headroom for real applications.

Backplane connector close-up

The expansion backplane: gold-plated pass-through contacts, one cable, sixteen addresses.

Controller and expansion boards mate through the enclosure — no ribbon cables, no adapters.

Main controller board

The Industry 757 main board: Ethernet, six RS-485 ports, isolated CAN, secure element.

From the Field

The platform is out of the lab: an NFT hydroponic greenhouse runs on an Industry 757 with PH-EC, 16DI and 16O modules — logging pH, conductivity and temperature around the clock, streaming to the cloud, updated over the air.

Real data, real events

The dashboard caught an unattended reservoir top-up from its EC and temperature signature — and now flags them automatically. Dosing steps, day-night thermal behaviour, probe health: it's all in the curves — watch them live.

Fixed from here

A firmware defect surfaced on the site's first hot day — diagnosed remotely and patched the same afternoon over signed OTA, no site visit. Read the full field notes →

Cloud Platform

Every controller ships cloud-ready: real-time dashboards, remote control and fleet firmware management — or point it at your own MQTT infrastructure (AWS IoT verified, with an on-board identity you own).

Self-describing devices. Add a module or a third-party Modbus/CAN device and it appears as data points — configuration, not code.

Fleet OTA. Signed firmware, dual-bank swap, trial period with automatic rollback — an update can fail without ever bricking a site.

Your cloud or ours. Per-device certificates and a configurable trust anchor: generate your own device identity in the secure element and connect to your own AWS IoT account — no dependency on us.
