The APLEX SiER-G4201M is an industrial 4-port RS-232/422/485 Modbus gateway designed to meet diverse industrial needs, serving as an industrial panel PC, HMI controller, gateway and industrial display monitor, all in one.

A key method to introduce AIoT into factories is creating a digital information environment. By facilitating data exchange between devices and the edge through networks, Modbus gateways and Ethernet switches become crucial in smart manufacturing. The APLEX SiER series, which includes the SiER-G1101M, SiER-G2201M and SiER-G4201M, provides a range of Modbus gateway solutions, while the SiER-S0802N caters to Ethernet switch needs.

The SiER-G4201M offers four COM ports and two LAN ports, functioning as a conversion bridge between the Modbus TCP protocol and Modbus RTU via RS232/422/485 serial and 10/100Base-TX RJ45 Ethernet ports. It also features an alarm function to alert administrators of any device abnormalities, and includes digital I/O for customised applications, allowing for real-time device status detection and logging.

Constructed with a rugged design, the SiER series has passed shock-proof and vibration-proof testing, ensuring durability in extreme conditions with operating temperatures ranging from -40 to 75°C and with a wide-range 12–48 VDC or 24 VAC power input.

APLEX’s visualisation software system supports edge computing and cloud computing configurations, enhancing the SiER series’ flexibility and capability in smart manufacturing.
