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.
The TCG120-4 is a compact 4G LTE telemetry module designed for reliable "last-mile" remote monitoring. Featuring 2 digital inputs, 2 high-voltage analogue inputs (0-60VDC), and 2 Form C relays, it provides automated local control and SMS alerting without network dependencies. It supports up to 4 Teracom 1-Wire sensors, making it ideal for point-to-point environmental and battery-bank safety tracking.
The TCG140-4 is a high-density 4G LTE sensor hub and edge data logger engineered for complex industrial setups. It expands capacity with 4 relays, 4 analogue inputs (including 2 selectable 4-20mA loops), and dual-bus architecture supporting 8 1-Wire sensors plus 8 Modbus RTU devices. Storing 70,000 time-stamped records internally, it ensures zero data loss during cellular dropouts.
The TCG210-4 is an ultra-low-power 4G LTE data logger optimized for remote environmental monitoring and solar-powered installations. Featuring an internal flash memory for 70,000 time-stamped records, it interfaces with up to 8 1-Wire sensors to track temperature, humidity, and voltage. Its advanced power management and deep-sleep cycles make it the definitive choice for off-grid, battery-operated telemetry sites.
