- QR · PayPass · cash
The electronics of one water vending machine in a single order: the M-AQUA controller runs dispensing, sensors and payment, a 3.5″ touch display shows the customer the tariff and the QR code to pay, and four Weidmüller relay modules switch the pump and the valves. The display firmware is already paired with the controller and the machine is set up in the cloud operator account before shipping.

Typical applications
- Retrofitting a water vending machine that has no cashless payment — controller, display and output relays in one order
- New machine builds where the integrator wants a matched controller, customer display and relay stage
- Small networks of machines that must all report to one operator account

Questions we get first
What is in the kit for €325?
The M-AQUA controller, a 3.5″ capacitive touch display with firmware that already talks to the controller, and four Weidmüller DRIKIT 24VAC 1CO LD relay modules. The machine is set up in the cloud operator account before shipping. The price is per machine, VAT excluded.
What is not included?
The hydraulics of the machine — pump, valves, filters, flow and TDS sensors — the payment devices such as a contactless terminal, bill acceptor or coin acceptor, the power supply and the enclosure. We can select the payment devices together with the kit.
What do the four relay modules do?
The controller outputs carry control signals; the machine loads go through the relays. Each module is a Weidmüller D-SERIES DRIKIT 24VAC 1CO LD: a plug-in relay on a DIN-rail base with a 24 V AC coil, one changeover contact rated 10 A, AgSnO contacts, a status LED and screw terminals. Four modules is the usual count for the pump and the dispensing valves; M-AQUA has 11 outputs, so more modules can be added to the order.
What does the display show?
The QR code for payment, the tariff and the menu, and the machine status while water is dispensed. It is a 3.5″ capacitive touch module on ESP32-S3 (320×480, Wi-Fi and Bluetooth, USB-C) in its own enclosure. It ships with firmware paired to M-AQUA; as a standard ESP32-S3 module it also takes your own LVGL interface.
Can the kit be fitted to an existing water vending machine?
Yes, that is the main use. The controller replaces the one in the machine, the display goes into the front panel and the relay modules sit on the DIN rail; the hydraulics, the bill and coin acceptors stay in place. Send the machine model and the payment devices through the form and we confirm the wiring before shipping.
Is there a warranty and do you ship abroad?
The hardware has a 12-month warranty. International shipping is by DHL or FedEx; we issue an invoice after the order details are agreed.
