Description
B8 Series –UCR-ST-B8
The UCR-ST-B8 is a Unitronics 4G LTE and Wi‑Fi industrial cellular router in the B8 series, designed for industrial remote access and IIoT use. The B8 series is positioned as a higher-spec model than the B5, with dual SIM support, more Ethernet ports, serial interfaces, GNSS, and additional I/O.
- Dual-SIM 4G LTE + Wi‑Fi support
- 4 Ethernet ports, typically 1 WAN configurable as LAN + 3 LAN
- Serial communications, including RS232
- GNSS / GPS support
- microSD and USB interfaces
- Claimed LTE speeds of up to 150 Mbps downlink.
We also have spare power connectors and DIN rail mounting kits for these.
Software/platform features
The router family can act as both a 4G LTE router and a UniCloud gateway for certain Unitronics PLC platforms. It also lists software features such as:
- Firewall
- Wireless AP/client
- Multiple VPN protocols
- Dynamic DNS
- NTP server
- Modbus TCP / RTU
- MQTT broker
- I/O control
- unitronics.cloud
