HBRX4D USER MANUAL Issue: 01

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.

1.2 PURPOSE

This document is the user’s manual for the HubBus four channel digital receiver

(HBRX4D). It provides an overview and a detailed description of the installation, use and

operation of the HubBus four channel digital receiver.

This document does not contain detailed information concerning the operation of the

HubBus system. Refer to the “HubBus System Description and Overview” user’s manual

(125-250-12) for detailed information on HubBus. Likewise, refer to the HubBus Safety

Manual (125-NNN-12) for any functional safety related specifications.

2 Warnings and Precautions

2.1 WARNINGS

WARNING: The HubBus Signal -ve line must not be tied to any common, 0V, ground or

Earth points.

WARNING: Do not use the same power supply as the channel generator. Any other

modules or equipment must be galvanically isolated from the HubBus channel

generators power source.

WARNING: The HubBus power source "Line-Ext" switch above the configuration port

connector MUST be switched to the RIGHT side (Ext).

WARNING: Ensure that the relay contact wiring is separated from the HubBus wiring by at

least 50mm.

WARNING: Operating the HBRX4D below the specified minimum switching requirements

will result in intermittent and unreliable operation of the output relay contacts.

WARNING: Operating the HBRX4D above its maximum switching capabilities will result in

unreliable operation of the output relay contacts and possibly result in welded

or open circuit contacts.

WARNING: If the HBRX4D is used in a manner not specified by Austdac then the

protection provided by the HBRX4D 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.

2.2 SYMBOLS

Markings that may be used across the HubBus range of products to indicate precautions

that must be taken to maintain safe operation of the system.

Caution, possibility of electric shock

Caution (refer to user manual)

2.3 PRECAUTIONS

•Only qualified personnel shall install and service the HBRX4D.

•Mains supply fluctuations are not to exceed ±10% of the nominal supply voltage.

2.3.1 USER ACCESS

There are no user serviceable parts within the HBRX4D. The user should not open

or disassemble the HBRX4D.

2.3.2 STORAGE, INSTALLATION, USE AND MAINTAINANCE REQUIREMENTS

The HBRX4D 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.

2.3.2.1 Storage

The specified storage temperature must be maintained during storage.

2.3.2.2 Installation and conditions of use

Prior to installation the HBRX4D should be inspected for the following;

•Any external damage to the enclosure.

The HBRX4D may be installed in any orientation.

The HBRX4D must be installed in a suitably certified IP54 or better

enclosure or as required by legislation. The enclosure should provide

adequate protection, from impact and ingress of dust and water.

The HBRX4D should be mounted to a stable surface avoiding areas under

constant vibration and shock.

3 Overview

3.1 GENERAL DESCRIPTION

HubBus four channel receiver with digital (relay) outputs. The HBRX4D can receive from

just a few (from 1) through to many digital (up to 2048) signals (ON, OFF or FAULT) from

a HubBus network to control the four relay outputs directly or via complex multi-term logic

functions.

Figure 1: HubBus four channel digital receiver

The digital receiver has four output relays controlled by up to six logic resolvers capable of

implementing OR, AND, NOR and NAND logic functions. Each resolver has an

independently configurable output ON and OFF delay filter to allow implementation of

simple timer functions.

For safety each relay output uses active driver circuitry such that a failure in any part of

the driver circuit will lead to the relay output failing to the safe mode (de-energised state).

Additionally, the physical positions of the relays are also monitored to detect other

dangerous failure modes such as frozen contacts.

3.2 OPERATION

3.2.1 Fault Monitoring and Prevention

The HBRX4D has advanced firmware and hardware features for increased safety

and reliability in preventing an undesired state of the relay outputs.

The relays are driven by a dynamic signal driven by firmware only if all internal

diagnostics indicate that the hardware is in correct working order. In addition to this

the HBRX4D has a second set of force guided contacts which are used to indicate

the current state of the relay contacts. If a fault is detected and the relays are

potentially in a ‘stuck’ state then a fault alarm is transmitted on the HubBus network.

Another relay may be used to trip on a fault condition to shut-down the system under

control.

3.2.2 Logic Resolvers

The HBRX4D digital receiver has six configurable multi-term logic resolvers of which

four drive relay outputs. These logic resolvers are typically used to implement
