Conveyor monitoring and control system

The Austdac SILBUS method of conveyor monitoring and control is unique in its one cable approach to both monitoring and control of long distance conveyors of up to 10km in length. Distances and functionality can be further extended using the new galvanic isolating repeater and network bridge. The system is internationally accredited by TÜV – the only one of its kind to be certified SIL3 rating, SIL 2, CAT3 and PL2.

The SILBUS’s unique transmission method allows for the combined transmission of high-integrity SIL3 conveyor emergency stop signals with monitoring and control signals for field devices such as belt alignment switches, tilt switches, belt rip switches as well as analogue values such as bearing temperature and vibration.

Signal monitoring

The range of signals that can now be monitored using the SILBUS range include digital, safety (SIL3), voltage, current, temperature and frequency all in a consistent family of DIN rail mounting or wire in modules.

Fieldbus products for underground mining

Austdac has released a new line of intrinsically safe fieldbus products specifically targeted at hazardous underground mining areas. This new family brings features such as ease of installation, improved ease of customer configuration and diagnostic capability.

Intrinsically safe mine telephone system

The ST2 intrinsically safe (IS) barrier 103 model telephone has recently been released into the Australian market. The system barrier is a digital link which isolates the PABX and provides IS lines to the underground phones.

Key features of the system:

• The 103 combines the features of the previous models
• The 103 phone is backward compatible to ST/1 series barriers
• Emergency button can store either a tone or dialled number (e.g. 555)
• Longer handset cord, with press switch operation
• Loudspeakers fitted for louder ringing volume (95dB+) and public address announcements from Phone Manager II
