T-Mod Remote I/O Telemetry Module

The Radius T-Mod I/O Telemetry Module is a compact device designed to transfer control and indication data as well as analogue signals from remote sites to a central hub. The T-Mod can be used as a simple mirrored I/O between two points or can be used to connect a large number of slave units to one central master device.

Configurable I/O’s
All the I/O’s are configurable, allowing any input to be transported to any output on any other device. In fact any one input can be shared across 4 other devices giving an element of peer-to-peer support.

Daisy Chaining
Multiple units can be connected together at both master and slave devices, so that the T-Mod can be scaled to suit the requirements of each remote station. One system can support up to 64 T-Mod devices and these could be all at one slave RTU or spread between a number of slave RTU’s

Connectivity
Each T-Mod unit supports 8 digital inputs and outputs and 4 analogue inputs and outputs. It is also possible to set any of the digital outputs as a communication alarm, if the unit loses communication contact with the master. Connection between the modules and to the communication devices is via RS485

Programming Interface
The T-Mod can be programmed either by a standard terminal interface such as HyperTerm or for speed of programming via a Windows programming tool. This allows the user to program the units graphically, by dragging inputs and outputs together on the screen to create the relationships between modules. The modules use an RS232 interface for configuration.

Modbus Protocol
The T-Mod uses Modbus RTU as its primary protocol allowing it to be connected to any host system supported by Modbus. It also allows for flexibility in the choice of communication devices.

Ready-to-Go
The T-Mod can be supplied as a ’ready-to-go’ package along with the Radius PDR digital data radio. The PDR data radio provides exceptional signal recovery and encryption for enhanced security as well as ’over-the-air’ error correction to ensure reliable communication over long distances. Moreover the PDR data radio has an in-built repeater functionality that allows any one data telegram to be automatically routed through up to 6 other units. This feature allows for extremely large geographic networks to be deployed.
