Every module in the TCG range provides global multi-band 4G LTE connectivity (with seamless 3G and 2G fallback) to ensure last-mile communication where local Ethernet or Wi-Fi is entirely unavailable. They feature a built-in web server for straightforward USB configuration, standalone automated logic processing, and native M2M protocol support including MQTT and HTTP/HTTPS POST (XML/JSON).
The TCG120-4 is designed for clean, reliable point-to-point telemetry. Housed in a compact enclosure, it provides the essential hardware I/O footprint required to track local conditions and remotely toggle electrical gear via SMS, HTTP API, or MQTT. It can also run completely offline, using its inputs to directly trigger local relays without needing server authorisation.
The TCG140-4 is a heavy-duty, industrial-grade powerhouse housed in a rugged metal enclosure with native DIN-rail mounting. Built to replace older, phased-out 2G telemetry gear, this universal module massively expands your I/O capacity. It features a massive internal data logger and full hardware support for standard industrial current loops and legacy serial machinery.
The TCG210-4 shifts the focus entirely toward autonomous, highly efficient data retention. It is specifically optimised for long-term deployment in areas lacking steady mains electricity. Running on an internal battery management layout, it spends most of its lifecycle in an ultra-low-power sleep state, waking up at pre-programmed intervals to read environment parameters, log them securely, and establish a brief 4G connection to upload data packages.
TCG120 is a remote IO control module that connects via a GSM/GPRS mobile Network. It has two digital and two analogue inputs, plus up to four 1-wire sensor support for temperature and humidity sensor. Two relay outputs for remotely switching devices (offering both normally open and normally closed wiring options). The controller can be used as a standalone device or as a part of data acquisition (SCADA) systems. The TCG120 and TCG120-4 (both 4E and 4G versions) are available.
TCG140 is a remote IO module that connects via a GSM/GPRS mobile Network. It has two digital and 4 analogue inputs, plus 1-wire sensor support for temperature and humidity sensor and up to 8 RS485 Modbus channels. Two relay outputs for remotely switching devices (offering both normally open and normally closed wiring options). The controller can be used as a standalone device or as a part of data acquisition (SCADA) systems.
TCG210-4 is a battery-powered 4G temperature and humidity logger with fallback for 2G Communication. The TCG210-4 includes an integrated temperature and humidity sensor with a wide operating range of −20 to 60 °C and 10 to 90% RH (non-condensing), making the unit ideal for cold-chain or ambient storage monitoring. The device will connect to a local cellular network and transmits readings to the cloud at defined intervals, and features internal storage for up to 70,000 readings. Can send alerts via SMS to up to 5 phone numbers. The TCG210-4 uses a Quad-band 4G LTE Cat1 with 2G fallback and can be used on road or air and is fully IATA DGR, IN 3091, PI970 Section II compliant.
