This versatile Ex nA and Ex tc certified Timer or Clocks can perform a host of timing and control functions, such as sampling or dosing, within a Zone 2 or 22 hazardous area without the need for Zener barriers or galvanic isolators, thus significantly reducing cost. An easy to use state and event structure enables relatively complex timing functions to be easily configured. Timing operations may be started and stopped via the inputs, or from the front panel buttons. The instrument display shows progress of the operation and international certification permits worldwide installation.

An internally powered backlight is available as a factory fitted accessory.

The instrument can be supplied configured and fitted with a customer specified printed scale card showing the units of time for no additional charge. Specified tag or application information can also be printed onto the rear of the instrument.
