Function :

This isolated barrier is used for intrinsic safety applications. It is a highly configurable timer that accepts a digital signal 

(NAMUR sensor/mechanical contact) from a hazardous area and is commonly used in applications 

requiring on-delay, offdelay, one-shot, or pulse lengthening. 

The output relay switch duration is easily adjusted, and a pulse divider function allows step-down ratios from 1:1 to 9999:1. 

A reset can be activated via dry contact switch and used to terminate a particular time function. 

The unit is easily programmed by the use of a keypad located on the front of the unit. 

Line fault detection of the field circuit is indicated by a red LED and through the collective error output via Power Rail.
