Austdac has released a new Intrinsically Safe large LED TRI-colour display unit, (changes colour depending upon trip level set) with it’s own trip amplifier for use in underground coal mines. The display unit is designed to accept a wide range of input signals.

This unit includes a SILBUS interface which allows it to be connected directly to any SILBUS system and can display any analogue signal on the SILBUS system. This display and trip amplifier can be used in conjunction with the SILBUS Gas, Conveyor and Longwall Systems.

Features
The features include:
• TRI-Colour LED display - 40mm high.
• Highly visible.
• Lower Current Consumption.
• 0.4 - 2V or 4 - 20mA input signal.
• Full latching and reset facilities.
• Rising / falling alarms.
• 3 adjustable set points with relay outputs.
• IP56.
• Available in a panel mount or stainless steel enclosure.
• Powered from any I.S. 12 volt power supply.
• SILBUS interface.

The unit is totally flexible and can be housed in various enclosures, from a small remote display to a large key reset enclosure, or an optional double sided display unit.

The display can be used without the trip amplifier where only high visibility is required.

One can also have more than one display attached i.e. Master Slave Configuration.
