Mounting Options for Industrial Large Digit Temperature Displays

WALL MOUNTING * 2.3” and 4.0” MODELS

Whether the display is to be mounted Indoors or Outdoors, they can be directly mounted to a WALL. Depending on the Size and number of digits in the display, side brackets are supplied or if the display is deemed to be too heavy for side brackets, we supply ‘ L ‘ shaped brackets for mounting the display directly to the wall.

If the display has side brackets these can be adjusted within the brackets to ‘ TILT ‘ the display downwards if it is mounted relatively high up. No WALL fixings are supplied for any brackets.

Wall Mounting

PANEL MOUNTING * 2.3”, 4.0”, 6.0” MODELS

This method of mounting is used when the display needs to be FLUSH FITTED into a Control, Panel Face. It therefore does not protrude like the WALL mounting display does. The case has a neat FLANGE around its perimeter to finish it off. Panel lock up brackets are supplied for this installation.

SUSPENSION MOUNTING

This method is used where displays need to be above head height so what is being displayed can be seen by the people working in an area who need to see it. All sizes of digits can be used for suspension mounting although normally this method is used with larger digits from 6” (150mm) upwards and again usually when the display is DOUBLE SIDED, although single sided displays can still be used.

Normally the display using this method will be HUNG from an overhead beam and suspended via CHAINS or a suitable secure method to a height best suited to the application.   No suspensions chains or similar hanging hardware is supplied for this.

Outputs for Industrial Large Digit Temperature Displays

RE-TRANSMISSION OUTPUT

All these Large Digit LED Displays,   offer RETRANSMISSION of the information being displayed to a Local Indicator or a Central Control Room.   This is available in 6 output forms

  • 0~10Vdc
  • 4~20mA
  • RS-232
  • RS-485
  • MODBUS
  • ASCII Only one re-transmission output can be chosen per display

ALARM OUTPUT 3A SPCO

The alarm is rated at 3A and is a SPCO.   The Alarm can operate any external device as well as SOUNDERS and BEACONS.

  • LO Alarm
  • HI Alarm
  • HI/LO Alarm The Alarms can be easily set by the user ( scalable )
