What happens today
A fault appears on a local controller. Somebody is called, drives, walks to the asset, reads a lamp or a code, and rings back — or presses reset and drives back.
Guided kit line · 57 panels, one BOM shape
Somebody is being paid to walk to a panel.
Vibration analysers, dust collector controllers, local control stations, analysers, dosing skids, pump stations, dam decant pumps, weighbridges, loadouts. Almost all of them expose UART, Modbus RTU or TCP, 4–20 mA, a dry contact, or a face made of pushbuttons and illuminated indicators — and none of them were designed to be reached from anywhere. PanelAccess puts a remote I/O module across that existing interface and drives it over 4G, NB-IoT, LoRaWAN or WiFi into a web app, PLC, DCS, historian, cloud or on-premises system.

The trip is the cost, and the delay is the damage
A 40 km round trip, an hour and a half of a technician's time and a vehicle is a few hundred dollars before anyone has touched the asset. The panel usually already publishes what is wrong. It simply publishes it somewhere a person has to stand.
What the kit changes
The same state is read from a browser or a PLC tag. A documented control input can be driven remotely. A C2 state is reported and escalated, and nobody presses anything.
Four BOM families, 57 applications
The controller, router, power supply, DIN enclosure and harness are shared. What changes is the interface in front of them and the number of I/O points. Families share a landed cost; each kit resolves its own price from its family plus its own I/O variation.
Family A · hardwired takeover
16 digital inputs, 8 relay outputs, PSU, enclosure, harness, 4G or NB-IoT router. Replaces the pushbutton and illuminator face of a legacy controller.
Family B · serial / Modbus
RS-485 or RS-232 gateway to the port the OEM documents, same PSU, enclosure and router. Read by default; writes only where the OEM documents a control input.
Family C · LoRaWAN sensing
A node at the asset and a shared gateway where one exists. No panel penetration and no output at all — level, temperature, vibration, bund, tank.
Family D · C2 monitor only
Isolated inputs only. The module has no output path — not disabled, absent. Fire panels, gas detection, safety interlocks, e-stop status, burner management, flare headers, deluge.
The 57 kits
Each row is a named application: the asset it replaces a walk to, the interface it uses, and the wireless path chosen for that site type. Ask for a written quotation and you get one for the kit you named.

The limit, stated once and enforced in hardware
8 of the 57 kits are C2 and monitor only: FirePanelWatch, GasDetectWatch, SafetyInterlockWatch, EStopStatusWatch, BurnerManageWatch, FlareHeaderWatch, DelugeWatch, H2SAreaWatch.
A fire panel, a gas detection controller, a safety interlock, a burner management panel — these are read, logged and escalated. The C2 kit cannot press the button, suppress an alarm or drive an interlock. Its controller ships with no output path to disable, the app renders no actuate control for it, and a kit with no classification is refused rather than defaulted. That market gets a window, never a hand.
The other 49 kits take over the panel, because the alternative is a person walking to it.
Guided DIY — what you do, what we do, what we will not do
The kit is supplied as parts, installed and commissioned by your licensed electrician. That framing is deliberate: we specify our terminals and the interface the manufacturer publishes, never a terminal inside your panel.
We specify
Every terminal on our own parts; the published interface we connect to (“the OEM documents Modbus RTU at 9600 8N1 over RS-485”); the method to confirm a point and prove isolation; power, fusing, isolation and surge requirements of our assembly; and exactly what the kit will and will not do once connected.
We never specify
Which terminal inside your panel or device; an interface the OEM does not document; mains work of any kind; a connection point identified from a photograph of your panel; or a SIL claim. If the answer depends on hardware we have not seen, the answer is a question back to you.
Request a quotation
Name the asset, the make and model, and the interface the manual documents. You get a written quotation and the interface method for that kit.
Questions this page should answer
Does the kit work on a panel with no network port?
That is the case it is built for. Family A takes over the pushbutton and illuminated-indicator face; family B uses the serial port the OEM documents. Neither needs the panel to have Ethernet.
Can it control a fire panel?
No. A fire panel kit is C2: it reports state and raises alerts, and the supplied module has no output path. There is no setting, licence or support agreement that changes that.
Who installs it?
Your licensed electrician installs and commissions it. We supply the parts, the interface documentation and the method; mains work and anything inside your panel is theirs.
Where does the data go?
Your choice of web app, PLC, DCS, historian, cloud or on-premises system. The router opens an outbound tunnel only; no inbound port is opened on the plant network.
Is this a certified product?
No. The kit is supplied as parts for a licensed installer, and no SIL, fire-system or gas-detection certification is claimed or implied. Certified work is a separate paid assessment, not a product.
