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.
RIGHT side (Ext) if using an external power supply. WARNING: If the HBTX8D is used in a manner not specified by Austdac then the protection provided by the HBTX8D 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.
2.3.1 USER ACCESS There are no user serviceable parts within the HBTX8D. The user should not open or disassemble the HBTX8D. 2.3.2 STORAGE, INSTALLATION, USE AND MAINTAINANCE REQUIREMENTS The HBTX8D should only be installed, operated and maintained by qualified personnel in accordance with the condition of safe use as outlined in the certificate. Ensure that all instructions and warnings are observed.
3 Overview 3.1 GENERAL DESCRIPTION HubBus eight channel transmitter with voltage free digital inputs. The HBTX8D may be configured for use with contact or NPN transistor inputs. Figure 1: HubBus eight channel digital transmitter The digital transmitter may be line powered or use an external supply. It detects the states of eight voltage free contacts and signals from devices with open collector NPN transistor output, e.g.
4 Installation 4.1 ENCLOSURE The HBTX8D 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 HBTX8D should be mounted on an NS 35 DIN rail. Optionally, a 16-position DIN rail connector can be inserted in the DIN rail.

Not available. Use MODBUS interface via the DIN rail bus. See below. 6.2.4 DIN Rail Bus To eliminate inter-module wiring a DIN-rail bus system may be used with the HubBus modules. The DIN rail bus is used to distribute the following: 6.2.4.1 HubBus module auxiliary power (10-48VDC) Any industrial rated power supply may be used.
Figure 7: NPN Input NPN inputs are also scanned at 50ms intervals but have a constant current source at the terminal. They have a terminal voltage of 3.3VDC and draw 3.3mA when pulled low by the NPN switch. The status of the inputs is shown on the front panel LED indication and is available as a HubBus channel or as a MODBUS register.
7 Configuration and Parameters The following are descriptions of system and device parameters. They are accessed via MODBUS parameters described in the following section. 7.1 CONFIGURATION PROCESS Configuration of safety devices follow the below process: 1. Enter the configuration option when the HHP1-H is connected to the device. 2.
