Teltonika TRB246 industrial cellular gateway with aluminium enclosure, RJ45 Ethernet port and terminal-block interfaces

Connect industrial controllers, utility meters and remote sensors through LTE Cat 4 with the Teltonika TRB246200500. This North American configuration uses a Quectel EC25-AF modem and includes a US power supply. Cellular rates reach up to 150 Mbps download and 50 Mbps upload, with LTE bands B2, B4, B5, B12, B13, B14, B66 and B71. Two Mini SIM slots support automatic switching when signal weakens, a connection fails or configured usage limits are reached. One 10/100 Mbps RJ45 port connects Ethernet equipment, with bridge and passthrough modes available for downstream devices. Bring serial and discrete signals into the same communications path through RS232, RS485 and configurable I/O on a 16-pin terminal block. RS485 supports 2-wire and 4-wire connections; RS232 includes TX, RX, RTS and CTS. Modbus client/server operation supports RTU and TCP, while DNP3, DLMS/COSEM, BACnet routing and OPC UA extend integration options. A Modbus-to-MQTT gateway links field equipment to an MQTT broker, and HTTP(S), MQTT and Azure MQTT support telemetry delivery to a server. GNSS supports GPS, GLONASS, BeiDou, Galileo and QZSS for location-aware installations. Operate from 9–30 VDC with reverse-polarity protection and maximum consumption below 3.5 W. The anodised aluminium enclosure measures 83 × 25 × 74.2 mm, carries an IP30 rating and operates from -40 °C to 75 °C. RutOS provides firewall rules, VLAN separation, WireGuard, OpenVPN and IPsec. WebUI, SSH, SNMP and Teltonika RMS support administration; DIN rail, wall and flat-surface mounting require additional kits.

Frequently Asked Questions

What is the difference between TRB246 and TRB246200500?▾

TRB246 names the industrial gateway model. TRB246200500 identifies its North American ordering configuration, supplied as a standard package with a US power supply. This configuration uses a Quectel EC25-AF modem and supports the North American LTE and 3G bands specified for that version.

Can the TRB246 connect RS232 and RS485 equipment to an MQTT system?▾

Yes. RS232 and RS485 connections are provided on the 16-pin terminal block, and the Modbus MQTT Gateway supports commands and data exchange between a Modbus server and an MQTT broker. Modbus RTU and TCP client/server modes support serial and Ethernet equipment.

Does the TRB246 support automatic switching between SIM cards?▾

Yes. Two Mini SIM slots support automatic switching for weak signal, data or SMS limits, roaming, unavailable or denied networks, and failed data connections. SIM idle protection can periodically activate the unused card to help prevent inactivity-related blocking.

What power and mounting arrangements does the TRB246 require?▾

The gateway accepts 9–30 VDC through two power connections within its 16-pin industrial terminal block and consumes less than 3.5 W at maximum. This package includes a US power supply. DIN rail, wall and flat-surface mounting each require an additional mounting kit.
