Rotation Speed Monitor
Opis
1-channel isolated barrier, 230 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 61511, Rated voltage: 230 V AC ± 10 %pa. 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. 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.
