Page 6: Introduction
1 Introduction 1.1 BACKGROUND AND CONTEXT HubBus is Austdac's long distance distributed I/O system used in a wide range of applications in non-hazardous environments. HubBus overcomes the limitations of other distributed I/O systems in terms of noise immunity from new variable frequency drives, number of channels for input and output devices, transmission distances on large overland conveyors and powering devices from the communications line. -
Page 7: Warnings And Precautions
All other HubBus modules and equipment must be galvanically isolated from the HubBus power supply. WARNING: If the HBSPCG is used in a manner not specified by Austdac then the protection provided by the HBSPCG may be impaired. WARNING: This product may contain chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. -
Page 8: User Access
2.3.1 USER ACCESS There are no user serviceable parts within the HBSPCG. The user should not open or disassemble the HBSPCG. The HBSPCG should be returned to Austdac for servicing and repair. 2.3.2 STORAGE, INSTALLATION, USE AND MAINTAINANCE REQUIREMENTS The HBSPCG should only be installed, operated and maintained by qualified personnel in accordance with the condition of safe use as outlined in the certificate. -
Page 9: Overview
3 Overview 3.1 GENERAL DESCRIPTION HubBus Single Port Channel Generator generates the HubBus signal, senses incoming transmissions and interfaces to the outside world. Figure 1: HubBus Single Port Channel Generator The channel generator requires a 48VDC power supply with at least a 3A capacity to drive the HubBus network. -

Failure of either of these levels is indicated on the front panel (‘STAT’ LED) and in Modbus registers. 3.2.2.3 HubBus Line Faults As well as under and over voltage detection, HubBus line current and line short circuit conditions are also monitored. The front panel (‘STAT’ LED) will indicate a problem and further information is in the Modbus registers. -
Page 12: Installation
4 Installation 4.1 ENCLOSURE The HBSPCG should be mounted in a host enclosure providing protection against dust and moisture. A minimum ingress protection of IP54 is recommended. 4.2 MOUNTING The HBSPCG should be mounted on an NS 35 DIN rail. Optionally, a 16-position DIN rail connector can be inserted in the DIN rail. -
