MiniLink, Compact modules
Add serial connectivity, digital I/O or CAN conversion where installation space is limited.
Small by design
A slim module can sit alongside the controller or instrument you already use. Start with the space available inside your device or enclosure.
Y301-110 / 200 / 020
Allow additional space for mounting, terminals and wiring. Other models have different dimensions.
View mechanical specificationsIntegrate with what you have
Allow for the housing, mounting tabs, terminals and cable bends. Radio models also need antenna clearance and a suitable antenna position.
Choose the serial variant, I/O combination or CAN format that matches your existing device. Confirm TTL voltage for the ordered version.
Check the model’s DC supply and mounting drawing. Keep terminal access and maintenance space clear inside the equipment.
Start from the function you are adding, then match the interface and installation space.
Y201, One serial port
Add the network your instrument or controller needs. Choose RS232, RS485 or TTL when ordering; each unit has one physical serial port.
| Model | Network |
|---|---|
| Y201-G | 4G Cat.1 |
| Y201-W | 2.4 GHz Wi-Fi |
| Y201-R | Ethernet |
| Y201-L | Private LoRa |
Y201-L forwards serial data over private LoRa; it is not LoRaWAN. Check cellular bands and local radio requirements.
Y301, RS485 Modbus RTU
Collect contact states and pulse counts, or add relay outputs. RS232 and selected TTL versions are ordering options.
| Model | Digital I/O |
|---|---|
| Y301-110 | 1 DI + 1 DO |
| Y301-200 | 2 DI |
| Y301-020 | 2 DO |
No built-in wireless. Network access needs a separate compatible gateway.
Y201C, CAN 2.0A/B
Exchange data between one CAN bus and one ordered RS232, RS485 or TTL interface. Match the CAN frame definition and serial format.
| Model | Conversion |
|---|---|
| Y201C | CAN ↔ serial |
No Ethernet interface. TTL voltage and firmware-dependent settings need a check for the supplied version.

No. The Y301-110 / 200 / 020 specification lists 77.4 × 22.5 × 16.2 mm. Y201 and Y201C dimensions differ. Use the selected model’s mechanical drawing and allow additional space for terminals, mounting, cable bends and antenna connections.
Check the equipment’s electrical interface, communication protocol and supply first. Y201 connects a serial device to the selected network, Y301 adds Modbus RTU digital I/O, and Y201C converts between CAN and serial. Network modes, data formats and device parameters still need to match.
No. Each Y201 has one physical serial port with the electrical interface selected when ordering. Network sockets are logical connections, not additional serial ports. Verify the TTL voltage for the supplied variant before wiring.
These three Y301 models are serial Modbus RTU I/O modules. Network access requires a separate compatible gateway. Y201-L carries serial data over a private LoRa link; it is not a LoRaWAN device or a direct MQTT uplink.
Describe the existing equipment, available installation space, supply voltage, interface and function you want to add. For a cellular link include the country and operator; for CAN conversion include the CAN frame definition and required serial format.
