Rotation Speed Monitor
Описание
This signal conditioner monitors for an overspeed or underspeed condition of a digital signal (NAMUR sensor/ mechanical contact) by comparing the input frequency to the user programmed reference frequency. 1-channel signal conditioner, 24 V DC supply (Power Rail), 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 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, Power Rail 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. A unique collective error messaging feature is available when used with the Power Rail system.
