Description
This isolated barrier is used for intrinsic safety applications. It monitors for an overspeed or underspeed condition of a discrete signal (NAMUR sensor/ mechanical contact) from a hazardous area by comparing the input frequency to the user programmed reference frequency. 1-channel isolated barrier, 115 V AC supply, Dry contact or NAMUR inputs, Input frequency 1 mHz .. 5 kHz, 2 relay contact outputs, Start-up override, Configurable by keypad, Line fault detection (LFD), Up to SIL 2 acc. to IEC 61508/IEC 61511pa. An overspeed or underspeed condition is signaled via the relay outputs. Line fault detection of the field circuit is indicated by a red LED and relay. The start-up override feature sets relay outputs to default conditions programmed by the user for up to 1,000 seconds. The unit is easily programmed by the use of a keypad located on the front of the unit. For additional information, refer to the manual and www.pepperl-fuchs.com.
