Rotation Speed Monitor
Opis
1-channel signal conditioner, Universal usage at different power supplies, Dry contact or NAMUR inputs, Input frequency 1 mHz .. 12 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: 20 .. 90 V DC / 48 .. 253 V AC 50 .. 60 Hzpa. This signal conditioner monitors an overspeed or underspeed condition of a digital signal (NAMUR sensor/ mechanical contact) 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 startup 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.
