Description
1-channel isolated barrier, 230 V AC supply, Dry contact or NAMUR inputs, Relay contact and transistor output, Adjustable output timer functions from 10 ms .. 60 min, Input frequency up to 80 Hz; pulse divider up to 1 kHz, Reset function, Configurable by keypad, Line fault detection (LFD)pa. 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, off-delay, 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. For additional information, refer to the manual and www.pepperl-fuchs.com.
