5 Way Communication/Power Rail for 19’’ Rack enclosure versions

Touchpoint Pro Communication/Power Rail

Power distribution for the Touchpoint Pro is via the Communication/Power Rail.

The Touchpoint Pro Communication/Power Rail provides direct power and network connection to the Input/Output modules, minimizing the wiring required. There is a single connection for the 24 Vdc supply and the network cables connect to the Ring Coupling module, which handles the communication between the modules and the central controller.

Depending on the power supply option chosen and the enclosure version, the Communication/Power Rail has space for 5, 7, 9, or 10 Input/Output modules. The Ring Network is the communication link between all Input/Output modules in a Touchpoint Pro system and the central controller. The Ring Network is the only connection required between a local Touchpoint Pro unit (containing the central controller and user interface) and remote Touchpoint Pro units. The Ring Network is implemented for redundancy as two loops transmitting in opposite directions (Ring A and Ring B). The network is self-healing since each module only communicates with the one next to it. If a module fails, the modules after it continue to transmit data in the direction away from the failed module, while the ones before it transmit in the other direction. Thus the Touchpoint Pro system can immediately detect and locate a failed module, without affecting the availability of the rest of the system.

The Touchpoint Pro Input/Output plug-in modules can be combined up to a maximum of 16 input modules (64 channels) and 32 output modules (128 channels). Modules can be located in any Touchpoint Pro enclosure and Touchpoint Pro accepts analog, digital and relay modules, making it one of the most flexible controllers available.
