This specialised range of sensors utilises the 1-Wire serial communication protocol to deliver cost-effective, digital telemetry directly to compatible Teracom controllers. Operating on a master-slave architecture, 1-Wire technology allows multiple digital sensors to share a single data line. It strikes an ideal balance between the basic on/off signalling of digital switches and the heavy-duty industrial infrastructure of Modbus systems.
The 1-Wire sensor line-up is optimised for simple, multi-point environmental monitoring across localised facilities:
By utilising a shared, low-voltage digital bus, Teracom 1-Wire sensors provide an efficient, plug-and-play approach to scaling up your environmental tracking.
For Teracom units utilising 1-Wire sensors, the network topography is highly sensitive to cable capacitance and signal reflections, requiring a strict linear daisy-chain topology rather than a star or branch layout. To maintain data integrity, Teracom recommends a maximum total bus length of 30 meters using standard UTP cabling, with any branches (stubs) off the main line kept to an absolute minimum (under 1 meter). Deviating from a single continuous line or exceeding this distance creates impedance mismatches, causing data frames to bounce back and corrupt communication, which results in intermittent sensor dropouts.
Designed for rapid, tool-less deployment, these climate and transmitter modules feature dual RJ11 ports for seamless daisy-chaining using standard patch cables. They are optimised for server racks, data centres, and clean office environments. Pair them directly with Ethernet controllers like the TCW241. RJ11 cables are available with tails for connection to terminal units.
Engineered for industrial facilities, plant rooms, and outdoor enclosures, these robust sensors feature internal screwless terminal blocks for direct on-site wiring. They allow field engineers to cut custom cable lengths, eliminating messy coiled slack inside electrical panels. These nodes match perfectly with terminal-equipped controllers like the TCG140-4 and require bulk twisted-pair or industrial alarm cabling.
These versatile, permanently potted sensor probes feature fixed-length cable tails designed for direct equipment monitoring, pipe temperature tracking, or liquid immersion. They can be hardwired into terminal enclosures or adapted into an RJ11 network.
