Ajuste del proyecto
Para máquinas y proyectos compatibles
Señales de necesidad
- Projects that need more than one interface path on one board.
- Fleets that mix MDB, pulse, relay, and serial equipment.
- OEM builds that need connector or firmware customization.
- Retrofit projects that also need data in their own backend.
Qué enviar
- Fotos de la máquina o placa actual
- Notas de interfaz o cableado
- Acción objetivo después de API o pago
- Si necesita carga de datos
No es adecuado si
- You need a replacement for the machine's safety controller or PLC.
- The machine has no controllable interface or usable feedback signal.
- You need a guaranteed multi-interface result before a sample.

Flujo de trabajo
De las fotos de la máquina al flujo probado.
Map the command
Define the API command, machine action, result fields, timeout, and fault behavior.
Test one machine
Validate the command, machine action, result, and reconnect behavior on a sample.
Configure the rollout
Confirm connector, firmware, quantity, and support before production.
Ejemplo de API
Ejemplo de comando de servidor o webhook para una acción del lado de la máquina.
Los campos del comando dependen de la interfaz de la máquina, el perfil de firmware y si el pago o la aplicación activa la acción.

Proyecto RFQ
Cuéntanos qué debe hacer, enviar o reportar la máquina.
Envía el modelo de máquina, fotos del controlador y la acción necesaria. Confirmamos la interfaz de Controlador multifunción y el siguiente paso de prueba.
A good first message
If you are unsure about the exact interface, send what you have. Photos often answer more than a long spec.
- Machine type and target country
- Machine photo, board photo, or wiring photo
- Action after payment or API command
- Need data upload? expected quantity?
Fastest first step
- Send a machine photo
- Describe the action after API or payment
- Tell us if data upload is needed
FAQ
Preguntas habituales antes de un test de muestra.
Can MDB, pulse, and relay work on the same board?
The board supports these interface blocks. Concurrent operation is confirmed against the target machine and firmware profile.
Can it replace a PLC or existing controller?
No. It is a machine-side control and data board. The existing controller and safety design remain part of the machine.
Can you customize connectors or firmware?
Yes, OEM customization is available after the machine interface and volume are defined.
What should I send first?
Machine model, controller photos, target action, data fields, and estimated quantity.
