Description
This signal conditioner analyzes 2 digital signals (NAMUR sensor/mechanical contact) and functions as a rotation direction indicator, slip monitor, frequency monitor or synchronization monitor. 2-channel signal conditioner, Universal usage at different power supplies, Dry contact or NAMUR inputs, Input frequency 1 mHz .. 1 kHz, Current output 0/4 mA ... 20 mA, Relay contact and transistor output, Start-up override, Configurable by PACTware or keypad, Line fault detection (LFD), Rated voltage: 20 .. 90 V DC / 48 .. 253 V AC 50 .. 60 Hzpa. Each proximity sensor or switch controls a passive transistor output. The 2 relay outputs indicate if the input signal is above or below the trip value or the rotational direction. The analog output can be programmed to be proportional to the input frequency or slip differential. The unit is easily programmed by the use of a keypad located on the front of the unit or with the PACTware™ configuration software. Line fault detection of the field current is indicated by a red LED. For additional information, refer to the manual and www.pepperl-fuchs.com.
